BDA Designs That Are Out of This World

BDA Designs That Are Out of This World

I read something the other day that blew my mind. Not surprising given the wide range of content available these days; however, I read it while editing a technical study guide for radio frequency communication systems. Technical study guides, by their nature, are never mind-blowing. Quite the opposite; editors struggle to make them interesting enough to ensure the reader stays awake. I was on the 25th chapter, deep into the weeds, in Section 8.7, Noise Floor and Noise Power. The section began with this icebreaker: Background noise exists everywhere as a remnant of the Big Bang. This is the leftover echo from the creation of the universe and provides us with an absolute minimum noise floor that can be calculated. I had to read that again to ensure I hadn’t drifted into the cosmos myself. Did this document, written by subject matter experts, state that the odd buzzing sound people call background noise or white noise is actually an echo from the universe’s explosive birth?

I am the Director of Communications at RF Solutions, an engineering systems integration firm specializing in radio frequency communications. In my role, I spend a lot of time reading and editing documents that describe radio frequency communications. There is no doubt that RF emissions are a fascinating topic. Humans cannot detect them with any of our five senses, yet they can be harnessed and used to transmit some of the most crucial information we possess. Discovered in the 18th century, these electromagnetic waves gave birth to wireless technology and have been used for telecommunication, military, public safety, space, and countless commercial applications ever since. But I had no idea that RF engineers used Big Bang’s echo, also known as cosmic background radiation or thermal noise floor, in their calculations. I sent Chris Godwin, our CTO, a text to get more insight. 

LJ: You design BDA systems using the leftover echo from the creation of the universe? 

CG: It’s very cool! We use it to ensure we don’t increase the noise floor at a tower site. 

You know we use amplifiers in buildings to boost signals from First Responder walkie-talkies so they can transmit to a tower or rooftop site for wide-area communications. That is known as the system’s uplink. 

LJ: Okay, but where does the creation of the universe come into play?

CG: Certain buildings require amplifiers covering a range or band of frequencies. These are known as wideband or Class B Signal Boosters. They amplify any signals within their bandwidth, including background noise, which you mentioned is the “echo from the creation of the universe.” If a system is poorly designed, the only way to get strong signals back to the donor site is to crank up the volume (system gain). The problem is that doing so also increases the background noise, sometimes making it impossible for First Responders to communicate. That is called Uplink Noise.

LJ: So, assuming we have no way to control cosmic background radiation, what do we do?

CW: When we design a system with a Class B Signal Booster, we thoroughly consider the background noise in our calculations, so we can ensure that when the signal from the amplifier reaches the donor site, the “noise” component of the signal is not above the thermal noise floor. When a BDA system is designed and installed correctly, you’ll never hear whispers from the Big Bang. 

LJ: I’m always impressed by the depth and breadth of knowledge our engineering team possesses, but on that particular day, it was otherworldly.

Does Your Building Need a Passive or Active DAS?

Does Your Building Need a Passive or Active DAS?

At RF Solutions, we design public safety and cellular enhancement distributed antenna systems (DAS) for high-rise buildings and other large venues. Cell DAS installations are almost always active solutions, but public safety systems can be passive, active, or hybrid. Before we begin to design a system, there are many factors to be considered. The optimal system design will depend on the unique characteristics of the building in which it will live and the communications requirements of local first responders. These factors include the coverage area, the design of the building, the building materials, signal source(s), and the project timeline. Once we’ve gathered the building particulars, we can determine whether the system should be passive, active, or a hybrid of the two. 

A passive system uses “passive” components like coaxial cable and splitters to distribute RF signals. Using coax to distribute the signal will produce a higher signal loss than an active solution. The further the antennas are located from the head end, the higher the signal loss, which results in lower downlink output power. These restrictions are the reasons why a passive system may not be appropriate for a specific building. 

An active system uses fiber optic cable to distribute signal between a centralized signal source (head end) and remote nodes placed strategically throughout the building. A hybrid solution is built upon an active system using fiber to distribute signal but relies on a passive DAS design for most signal distribution. Buildings with unique challenges might benefit from a hybrid solution. 

When determining if a building needs an active system, there is no magic size (square footage) number per se, but it usually falls around the 1million sq. ft. mark. However, there are many sub-1mm sq ft buildings where we’d choose an active system. You could easily have a 750,000 sq ft legacy hospital facility with dense walls and floors that will need to use an active system to meet the required coverage because RF signals will have poor penetration. Many older (pre-war) buildings present these same issues. A new, smaller building might require an active system if it’s steel reinforced. A warehouse with heavy shelving and dense stored materials may need one as well. Conversely, a +1mm sq. ft football stadium might not require an active system due to the open architecture. That’s why it’s so important to understand the propagation characteristics, like wall density, building composition, and building age, before starting the design. 

You might ask why not always use an active solution? The simple answer is cost. Active systems are expensive, but an added benefit of using a fiber DAS is that it’s future-proofed. Using fiber provides the unique ability to upgrade when new technologies or frequencies must be added to a system. Converting the radio signals to light over fiber allows the use of multiple distribution points (nodes) with little or no loss in the transport system.

So, you see, there isn’t a hard and fast rule you can use to determine which way to go with your public safety DAS but knowing all the building’s characteristics and technology requirements beforehand will steer you in the right direction. 

Don’t Let Your ARCS Approval Stand Between You and Your Building’s CO

Don’t Let Your ARCS Approval Stand Between You and Your Building’s CO

On October 1, the NY Times front cover of the Sunday Real Estate Section featured an article entitled, “New Supertalls Test the Limits, as the City Consults an Aging Playbook.” The piece highlights real estate developers’ strategy of continually renewing their NYC Department of Buildings Temporary Certificate of Occupancy (TCO). The article focuses on the city’s 25 tallest occupied buildings, but the truth is, there are hundreds of occupied buildings throughout NYC without a final CO. 

One of the requirements for receiving a final CO in a high-rise building is an FDNY Letter of Approval for the building’s Auxiliary Radio Communications System (ARCS). An ARC System provides vital communications for FDNY firefighters in an emergency, and the mandate for these systems came after 343 firefighters died on 9/11. At RF Solutions, our project managers join a project at its inception and play an integral role, providing consistent oversight throughout a project’s lifecycle. We do everything we can to ensure that our FDNY filing, testing, and certification are completed without delays. Building owners sometimes hire us mid-project when other companies have failed to get their systems approved. In the long term, it’s in everyone’s best interest to take the necessary steps to receive a final CO.

The last quote in the article seems like a harbinger for the future. “My view is, if the building doesn’t have a final C.O., there should be a public notice on the front door,” Mr. Young, the former DOB plan examiner, said. He fears that change will only come after something goes wrong. “One disaster will change all of this.”

Since our firm’s inception in 2016, we’ve received over 150 FDNY Letters of Approval for our ARC Systems. If your building requires an ARCS, reach out to find out why we are the right choice.

Superior Products Backed by Decades of Experience

An Auxiliary Radio Communications System (ARCS) provides first responders with a fail-safe method of communication via an enhanced two-way radio amplification system. The system allows firefighters to receive and transmit communications throughout a building during an emergency. There are three major components of an ARC System – the Dispatch Radio Console (DRC) at the Fire Command Center, a Radio Amplification Unit (RAU) that receives and retransmits the radio signals, and a Cable and Antenna Plant (CAP), which consists of antennas strategically placed throughout the building to ensure radio coverage. In addition to functional requirements, the FDNY has established precise standards for ARC System hardware and software and the approval of companies and technicians authorized to test and maintain these systems. 

And while all ARCS products essentially do the same thing, there are subtle differences that a client might not realize until after their building’s system has been installed. These variations in ARCS equipment relate to reliability and ease of use, directly impacting the long-term cost of operating the system. When our engineers first designed our products, they looked beyond the basic FDNY requirements to ensure that these critical, life-safety systems would be of the highest quality and reliability, while at the same time, intuitive and easy to use. Our products are built in the US by a manufacturing firm meeting ISO 9001 standards. We voluntarily complied with President Obama’s Executive Order 13636 (“Improving Critical Infrastructure Cybersecurity”) and chose to engage a certified, US-based developer. 

Our software development team understood that it was crucial to have a system that is easy to operate while maintaining exceptional reliability. All software systems are designed and supported by us here in the US.  We made sure that our user interface was intuitive so that the personnel tasked with using and monitoring our equipment, the members of the FDNY, and the building service staff, don’t need a background in software engineering to test and service them. 

As an example, all ARC Systems must indicate an alarm if the RAU door is opened. Other ARCS equipment requires a tech from the manufacturer to come on-site to reset it – an expensive and completely unnecessary task. With our equipment, if the condition that caused the alarm is remedied, it can be cleared with a push of a button. Some of our alarms reset automatically when the condition clears, such as AC Power Fail when the AC power returns. We have programmed our RAU Tamper Alarm to “latch” and stay on until manually reset by pressing the Test button on the DRC. These enhancements in our software significantly reduce the need for service calls. We know these variations in product usability exist because, as an FDNY ARCS-certified firm, we are often called in to test and service other manufacturer’s products. We believe that once an ARC System is installed and approved, a client should have the flexibility to call any ARCS-certified company to test and inspect the system and not be beholden to the manufacturer.

Our company’s experience and engineering prowess is a value-added ingredient, and we continually upgrade and refine our equipment. Recently, we enhanced our software to protect against cyber-attacks and malicious intrusions. Access is restricted to authorized personnel only. We’ve also included an event-logging feature that can be used for diagnostic and forensic purposes. Our manufacturing quality has been consistent since we first started our company five years ago. You will never see our engineers performing “field construction,” something that happens more often than you might think. Our proprietary ARC System electronics have been tested in an ETL facility to meet exacting UL standards. Simply put, all ARCS equipment may appear the same at the time of purchase, but, over time and with use, the differences will surface, costing the client valuable time and money.   

Grid Testing: You Can’t Get the Gold Without the Grind

Grid Testing: You Can’t Get the Gold Without the Grind

Grid testing emergency responder radio communication systems is mandated in the International Fire Code 510.5.3 to ensure adequate signal coverage throughout a building, including areas not typically prioritized for cellular coverage, like stairwells, escape routes, cellars, mechanical floors, and rooftops. Once a system is installed, the building owner must have the radio system tested to verify that two-way coverage on each building floor is not less than 95%, or 100% in critical areas. Grid testing isn’t complicated. Each floor of the building is divided into a grid of 20 approximately equal test areas. Two technicians are required. One stands at the control center, and the other moves throughout the building to stand in each of the 20 grids on each of the floors. The test is conducted using a calibrated portable radio of the latest brand and model used by the AHJ (Authority Having Jurisdiction). In some jurisdictions, like NYC, we must record each grid test’s audio and submit each of these files to the FDNY for review and acceptance. 

Sounds simple, and it is. What doesn’t come across in the description is the absolute tediousness of the process. The tech exchange goes something like this:

            Tech 1 (on the 25th floor): “Floor 25 Grid 1 Area 10 Channel 11.”

            Tech 2 (at the command center): “Floor 25 Grid 1 Area 10 Channel 11 DAQ 4.5.”

            Tech 1: “Floor 25 Grid 1 Area 10 Channel 12.”

            Tech 2: “Floor 25 Grid 1 Area 10 Channel 12 DAQ 4.5.”

DAQ, or delivered audio quality, is the most common signal quality measure for public safety systems. Although the minimum DAQ code requirement is 3.0, the accepted objective is to provide DAQ 3.4 over the entire service area. DAQ 3.4 is defined as speech understandable with repetition only rarely required and with some noise and/or distortion. A lower DAQ may require excessive speech repetition, while a higher value may require a prohibitively expensive infrastructure investment. 

The back-and-forth exchange between the two techs can take over a week of 8-hour days, depending on the size of the building. The techs require laser focus to ensure the system works in every nook and corner.  Our techs know their work is critical, no matter how tedious, because first responders depend on it. Any deficiencies in coverage are identified and will require remediation, or the system will not receive approval.  Delays in approval can hinder the acquisition and maintenance of occupancy permits. Mandatory yearly inspections can uncover degradation or impairment that is not yet severe enough to trigger system alarms. This deterioration could result from partial equipment failure, damage to antennas or cabling, or changes and renovations within the building. Proper testing takes time and costs money, but these systems rely on it, as do the first responders who use them to save lives. You may have heard of Malcolm Gladwell’s theory that “ten thousand hours is the magic number of greatness.” To be considered elite and truly experienced within a particular craft, you must practice it for ten thousand hours. If that’s the case, our grid testing technicians set the gold standard.

Is Your ARC System in Compliance?

Is Your ARC System in Compliance?

Building owners in NYC breathe a sigh of relief when their ARC System passes inspection because it’s one of the last steps before their building receives a Certificate of Occupancy. The 2014 NYC Building Code requirement for these systems has placed them top of mind for building owners. However, you might be surprised to find that many building owners overlook a critical section of the code that requires annual inspection and recertification. It’s important to note that when it comes to life-saving communications, they’re only as good as their last certification. A public safety system protects the public and the first responders who depend on its availability. Therefore, regular testing is vital to ensuring reliable service. A qualified public safety support team provides a building owner with peace of mind knowing they are covered in case “as and when” becomes “911, what is your emergency?” 

Just because you can’t see what lives in your building’s cable infrastructure doesn’t mean you should stop worrying about what’s in there. The space where your public safety cables live is shared with various voice and data system cables, mechanical pipes, HVAC equipment, and IT networks. All of these require ongoing maintenance and sometimes complete renovations. This buzz of activity over the life of a building significantly increases the chance that a public safety DAS cable becomes damaged. 

Many property owners might not know they are out of compliance or legally required to ensure their equipment never goes out of service, but more importantly, they might not realize this fact until it is too late. First responders rely on these systems in an emergency, but maintenance of these systems is sometimes ignored. Over time the active equipment, including the RAU and DRC, can require routine maintenance. That is why regularly scheduled maintenance and testing are so essential.  

In New York City by code, the ARC System components must be inspected and tested annually to confirm that the system is still in good working order. The certification document is then submitted to the FDNY for permit renewal. When an ARC System turns five years old, the system must be recertified. This process requires a radio coverage survey of the system, conducted in the same way the original commission test was performed. The results of the five-year recertification test are then compared to the initial commissioning test to determine whether there’s been any degradation to the system’s performance. Successful recertification results also require submission to the FDNY for permit renewal.

In many cases, especially in new construction projects, the building owner may not know about these annual maintenance and certification requirements. At RF Solutions, we are working to keep the building owner, and property managers informed to remain in compliance and ensure the system works when there is a real emergency. 

Reception Killer Quesque C’est?

Reception Killer Quesque C’est?

It seems illogical that in 2021 getting good cell reception is still an issue, even in state-of-the-art supertalls in New York City. But the reality is, five bars are never a given. Several factors adversely affect the ability of a cellular network to reach subscribers inside a building. Today’s sustainable construction materials improve structural integrity and energy efficiency but wreak havoc on the ability to propagate wireless service. Low “e” glass, thick concrete walls, and steel construction can restrict wireless signals from penetrating a building. Signals often can’t reach the higher floors of extremely tall buildings, as the surrounding cell towers are lower than the upper floors. The good news is, there is a way to counteract these reception killers; cellular enhancement using a Distributed Antenna System (DAS).

A distributed antenna system, also known as an in-building wireless system, is cutting-edge technology that provides robust, dependable cellular service throughout a building. Each design is unique and custom-tailored to the building in which it lives. The DAS signal source receives cellular signals from the wireless service providers. Using wall and ceiling mounted antennas distributed throughout the building, the signal is amplified and disbursed throughout the structure. 

As a wireless system integrator, we perform benchmark surveys of the physical site to determine existing signal strength and propose the best possible solutions. Once it’s determined that a DAS is required, we use the building’s CAD files to create a custom design using iBwave®, the industry standard for inbuilding wireless communications. Accommodations are made for the building’s other radio systems, like public safety, to account for the coexistence with additional frequency transmissions. We also coordinate activities during the DAS implementation between the carriers, property owner, and installation team. Our Project Managers are well versed in the NFPA, IFC, electrical, and building codes required for in-building systems for cellular enhancement and public safety. They join a project at its inception and play an integral role over the project’s lifespan. A building’s lifecycle is long and justifies careful and informed design when it comes to communications. There are many reasons you can have poor cell service in a building, but that shouldn’t be an excuse. 

2020 Foresight

2020 Foresight

I want to think that when we started our company in 2016, we were anticipating events like a global pandemic because that would make us an incredibly visionary group of people. However, it wasn’t the fear of contracting a virus that motivated us to create an entirely mobile company. It had more to do with the fact that we anticipated that our employees would need to be mobile and able to communicate with clients and colleagues from our multiple offices. As a team of engineers, we are always looking for creative solutions, especially when it comes to technology. The tools that we put in place to make work an activity, not a location, allowed for a seamless transition when construction halted in New York, and we no longer worked out of our office spaces. 

For example, we have always held our Monday morning meetings via Zoom, bringing staff together, no matter where they were physically located. When we all started working from home in mid-March, that weekly meeting became a vital tool for collaboration for pre and post-sales tracking and project management. Again, other web-based applications like Mondayand BuilderTrend are the source of our discussions.  Our talented engineering team uses iBwave daily.  Remote access to this tool enables them to create accurate designs of indoor wireless networks. MS Office 365’s online productivity tools, including SharePoint  allow for easy file sharing and storage. Microsoft’s Teams has become our company’s go-to method of communication, and everyone in our firm keeps it open on their desktop at all times. In many ways, this “always-on” access has improved our communication and response time. All of our cloud and web-based apps are accessible from our phones and tablets as well. We recently built a mobile app in Microsoft’s PowerApps to give our engineers and project managers access to vital project information while visiting construction sites. 

We’ve found that our employees can be just as productive or even more so when working from home. The foresight we had in 2016 has made our firm nimble, accessible to our clients, vendors, and one another, and helps with efficiency and improved response time. The one thing these systems can’t do is replace the banter I enjoyed over lunch with my colleagues. I look forward to sharing meals with them in the not so distant future. 

A Firehouse Chat

Posted on by rfsolutions

A Firehouse Chat

Today, October 28th, is National First Responder Day. Congress designated the day in 2017 to honor the firefighters, police officers, and EMTs that rush into a crisis when the rest of us run out. Living and working in NYC, I have many opportunities to stand and watch in awe at first responders’ unimagined bravery. I’ve often wondered what they think when the alarm goes off. Do they worry about what they’ll encounter? 

“No, I don’t even think about it. It’s my job. It’s what I’ve been trained to do,” explained Pat Parrott, a member of FDNY’s Engine 54, Ladder 4, Battalion 9 in the heart of NYC’s Theater District. 

Pat was kind enough to meet me at the end of his shift to answer my questions about a NYC firefighter’s life. Firefighter Parrott started with the FDNY in 1995, assigned to a house in College Point Queens, but was transferred two months into his “probie” year to the “Pride of Midtown,” where he’s been ever since. His firehouse is well-loved in the neighborhood, and even received a Tony award in 2019 – The FDNY Engine 54, Ladder 4, Battalion 9 are more than deserving of the Tony Honor — they are an integral part of our industry, conducting inspections in our theaters, keeping thousands of theater fans and industry members safe every single day — and they have never missed a performance!

I asked Pat about two aspects of the FDNY that I’ve read a lot about; tradition and innovation. 

“Mealtime is very big in the firehouse. Everybody gets involved in cooking for the officers, and it brings everybody together. Dinner is the biggest, but we do lunch too.” I asked what was on tap for lunch, and he said he heard rumblings about sausage and peppers. Is everyone a great cook? “It depends on who’s on duty.” For Thanksgiving and Christmas, they go all out. Turkey, prime rib, the works. 

I was happy to hear that when asked about innovation, Pat mentioned that one of the most significant improvements, since he’s been on the job, is communication – namely, the Auxiliary Radio Communication Systems (ARCS) that the FDNY mandated after 9/11. “The new systems help a great deal, compared to what we worked with when I first started. Back then, you could have somebody a couple of floors above you, and you couldn’t communicate. You’d actually have to communicate with the firefighters in the street, and they’d relay the information to them. It gives us a better understanding of what we’re dealing with.”

I asked what affects the pandemic has had on firefighting, and he said, “Of course, there are the obvious changes, like wearing masks around the public, but fighting fires in NYC, we are always dealing with traffic. These days, the volume of traffic is nothing like it was so we can respond much quicker.”

Brandon joined us at one point in the conversation, a young member of the FDNY who started in November of 2016. I asked him his thoughts on his career choice. “It’s the best job in the world. It gets serious at times, but I like it. It’s great camaraderie, being part of a team, we’re really a family—great guys and girls. You can’t beat it. Other people might say, ‘I have to go to work today, I say, I get to go to work today.'” 

I asked Pat about the attributes that make a great firefighter. “Being outgoing helps a lot. You’re always interacting with the public. But being a good person is the most important thing. And being in good shape helps.” 

What does a typical shift entail? “We start with roll call in front of the rigs. We have three companies, and each company has five members and an officer working on the tour. We go over our assignments for the day; for example, today, I’m operating on the outside, so if there were a fire on the third floor, I’d go up the fire escape and vent the windows. There is also an interior team responsible for forcible entry. Then, we’ll do committee work, which is cleaning the house and washing the rigs. We’ll go food shopping and prepare for the meal. We do drills with apparatus on the truck, like the Jaws of Life. We’ll check all our tools to make sure everything is squared away.” 

Are there days when nothing happens? He laughed. “No. Around here, something is always going on.” “The Pride of Midtown” is one of the busiest firehouses in Manhattan. They answer around 14,000 calls a year from Broadway theaters to restaurants and hotels, skyscrapers, and even assist with rescues in the Hudson River. 

When our conversation was coming to a close, I asked about 9/11. “Everything seems to go back to that,” Pat said. The 2001 terror attacks took the lives of 15 members of the hook and ladder crew who were among the very first responders at the World Trade Center. Pat showed me the tribute wall in the firehouse with the images of the members they lost that day. No firehouse in the city paid a heavier price on 9/11. “The whole house. We lost every member that was working that day from this firehouse.”

I thanked Pat for his time and walked out of the firehouse into the busy midtown morning. I had an appointment at a nearby blood bank. Later in the day, I got an email thanking me for being a hero and a first responder. All I could think was “not even close.” 

Project Managers Are the Electromagnetic Force of Our Organization

Project Managers Are the Electromagnetic Force of Our Organization

The hats our Project Managers must wear are many; the skills they must have are diverse. In-building public safety systems can take years to complete and include various sub-contractors and local authorities throughout a project’s lifecycle. They require consistent oversight over long periods, which is why excellent project management skills are so crucial in our business. Any delay in the timeline could mean a delayed Certificate of Occupancy for the building’s owner. Our rapid growth since our firm’s inception in 2016 wouldn’t have been possible without their technical expertise and steady hands on the tiller. 

Jude Fauteux, the first Project Manager we hired, started with RF Solutions in June 2017. Since then, he’s been responsible for getting many of our Auxiliary Radio Communication Systems (ARCS) over the finish line and receiving their FDNY Letter of Approval. Some of his recent successes include three projects in the Bronx, a mixed-use project in the Soundview neighborhood, an affordable senior housing rental apartment building, and the redevelopment of a long underutilized manufacturing district, overlooking the Sheridan Expressway and the Bronx River, as well as a 32 story tower in Brooklyn. 

Neil Shore started with us in August 2018, having spent decades working as a product specialist at Mercedes Benz, USA. Neil is known for surpassing expectations to receive the sought after FDNY Letter of Approvals. Some of his recent projects include a 10-story affordable housing building developed by L+M Development Partners and B&B Urban in Brooklyn, a distinguished new property with 11 boutique residences built by Extell Development Company in Manhattan, a 14-story building with 82 apartments, part of Locust Manor Estates in Queens, a new apartment development by Velocity Management in Brooklyn, a unique, state of the art office building in Noho developed by CBSK Ironstate, and a 25-story residential tower developed by SHVO, in the up-and-coming Hudson Square bordering Soho. Many of these projects are repeat clients. Neil says, “I will go to any length to get the job done. The show must go on!”

These are just two members of our project management team. Our PMs have many years of construction management experience and have acquired substantial knowledge of RF propagation and principles. They are well versed in NFPA, IFC, electrical and building codes required for in-building systems in public safety and cellular enhancement. Our PMs join a project at its inception and play an integral role over the project’s lifespan. The PM begins with a top-level project review with clients to discuss the design and the proposed implementation. They’ll ensure all of the system’s components on the Bill of Materials arrive safely at the job site. They take the time to train the installers on reading blueprints and proper cable installation. They return to the job site to confirm the installed system meets our firm’s expectations so that when the time comes for the inspection, there are no surprises. And finally, the PMs submit the necessary documents to the FDNY for filing. Our PMs are on the frontline, managing all aspects of the project, ensuring adherence to all regulations and requirements. They see the big picture, and they are excellent prioritizers. And, they almost always do it with a sense of humor and a smile. At RFS, we take pride in the work we do, and it’s incredibly rewarding for our PMs to know that they play a part in making NYC safe for the people who live and work there.

…And This Dragon Eats Fire

…And This Dragon Eats Fire

Installing coaxial cable for public safety deployments may never be the same.

Radio Frequency Systems (RFS), a world leader in indoor RF coaxial cables, recently announced the launch of its revolutionary new product, DragonSkin™, the first and only in-building coaxial cable certified by UL to survive two hours under fire conditions without any additional protection. DragonSkin™ cable continues to support cellular and public safety radio communications in temperatures up to 1832°F for two hours. 

How Would We Use It?

RF Solutions is very excited by this new product, especially when it comes to retrofits. Installing in-building communication systems in occupied legacy buildings can be quite challenging. Often, we don’t know what we’re going to find until we do the initial site walk. It’s not unlikely to find a slew of existing cables in a low hanging ceiling, leaving little to no room to find viable cable routes, let alone the space to build soffits or add fire barrier wrap. This type of project would be the perfect utilization of DragonSkin™. At only half an inch in diameter, 

DragonSkin™ is thin and lightweight. It’s also flexible, maintaining its seven-inch bend radius, and can be installed and connected like any standard RF coaxial cable, saving considerable time, effort and money compared to alternatives.

Another example of where DragonSkin™ would be a game-changer is a retrofit of a landmarked high-rise where aesthetics is of great import. Coop boards and building owners can have precise demands regarding the appearance of installed systems, even when they are in the basement. Soffits and fire barrier wrap are bulky, and to many, unsightly, however up until now, they were the only options. Going forward, I can see a lot of clients requesting this groundbreaking new cable. 

And then there’s the late in the project situation when we get a call, and the contractor is looking for a small run, perhaps 20-30 feet of fire-resistant cable to solve a problem with less mess in a less intrusive manner. Once again, DragonSkin™would slay it. 

Sounds Amazing, But What Does It Cost?

This is the product we’ve all been waiting for, but I worried it would be cost-prohibitive. So, I reached out to Tom Kuklo, Global Product Manager – Indoor Solutions, at Radio Frequency Systems, to find out. “We did a study and found that the two viable options for retro-fits available on the market today, custom metal soffits, and fire wrap, can be up to 2.5 – 3.5 times the cost of installing DragonSkin™ due to labor-intensive construction and additional materials required. These additional measures increase cable size, weight, and cost. They also reduce the cable’s bend radius, making installation more difficult, time-consuming, and expensive — especially in cases where existing buildings are being retrofitted to meet standards. And only DragonSkin™ carries the official UL 2196 certification.”

Coming to A Distributor Near You

“Our methodology for going to market is through our key channel partners. We are finalizing our first products, and plan to ship to distribution this week. We are in start-up mode and expect to get to full production this quarter. Shipments to distribution for orders will begin in volume in May,” explained Tom. 

At RF Solutions, we are taking a look at all of our projects coming down the pipe, looking to see where we can best utilize this pioneering technology.

That’s An E-Wrap!

Some of the most challenging projects in the public safety arena involve older, occupied buildings, and the planning and implementation of bringing them up to code. These retrofit installations are even more challenging when it comes to healthcare facilities. 

RFS recently implemented an ARCS project at a top-tier medical research facility located in the medical corridor of Manhattan’s Upper East Side. This facility was undergoing an extensive renovation, which triggered the requirement for an FDNY ARC system. The RFS engineering team was able to overcome some of the cable installation challenges on the upper floors with a unique design that allowed for overlapping antenna coverage. This plan negated the need for two-hour fire rating protection of the horizontal cable runs. However, the next problem we faced was the two lower floors. The parking garage was open and exposed without ceilings, leaving us no option to build a soffit to protect the cables. Fortunately, we found a perfect solution to our problem when we brought in Specified Technologies (STI), and their E-Wrap Endothermic Wrap product line. E-Wrap is a protective wrap designed for fire protection of critical circuits and infrastructure such as fire pumps, signaling equipment, elevators, alarms, process control equipment, or emergency responder radio communications systems (ERRCS). When installed around Electrical Metallic Tubing (EMT), conduits, or cable trays, E-Wrap™ releases chemically bound water, which has a cooling effect providing up to 2 hours of circuit integrity ensuring continued operation under fire conditions. 

The job was significant in size, requiring several hundred feet of cables and E-Wrap, but STI worked within the construction schedule. STI provided engineered solutions for the protection of over 900 linear feet of conduit as well as dozens of junction boxes throughout this retrofit ARCS project. STI’s proprietary E-wrap provides a fire-resistant enclosure, where traditional means of enclosure was simply impossible.  “With the help of the RFS and the installation team, STI was able to identify many conditions and custom tailor engineered solutions backed by real-world testing to ensure the best possible deliverable to the client.  Having a partner like RFS, with their deep commitment to quality, is invaluable to the process,” said Dan DeSantis, Territory Manager, STI.

ARC systems are custom designed for each building in which they reside. At RFS, we continually look for creative, cost-effective strategies to meet the rigorous requirements of the FDNY. Our systems save lives, and we take pride in the work we do. It’s incredibly rewarding to know that we play a part in making NYC safe for the people who live and work here. 

The Call for Robust, Reliable Communications for First Responders Nationwide

Posted on by rfsolutions

The Call for Robust, Reliable Communications for First Responders Nationwide

In 2005, the US National Institute of Standards and Technology (NIST) issued its Final Report on the Collapse of the World Trade Center Towers (NCSTAR1). This comprehensive report included 30 detailed recommendations for improving the safety of buildings, occupants, and emergency responders. One of the essential elements addressed the need for robust, reliable radio communications for first responders. The general public had a misconception that such in-building coverage already existed when, in fact, it was inadequate in almost every circumstance.

National Standards Created for ERRCS

In response to this report two standards organizations, the International Code Council (ICC) and the National Fire Protection Association (NFPA), created standards for the design and installation of Emergency Responder Radio Communications Systems (ERRCS). These standards are similar in scope and are incorporated into the statewide building “Fire Code.” A few major cities (such as NYC, Boston, Philadelphia, District of Columbia) have developed their own, more stringent requirements based on comprehensive planning for various response scenarios. Outside of these cities, the national codes empower local AHJs (Agencies Having Jurisdiction) – typically the local fire departments – to regulate specific in-building radio coverage. These regulations are based on planned first responder operations within their communities. Under the enacted codes, building owners are responsible for installing infrastructure within their buildings to meet the requirements set forth by the local AHJ.

A Failure to Communicate

Public Safety Agencies (PSA) typically have their own radio communications system for coverage throughout their area of operation. Unfortunately, radio signals do not penetrate buildings well. Large buildings typically have many “dead areas,” especially in the center of the building, on floors housing mechanical and electrical equipment, and in below-ground levels. These are critical areas where firefighters and other first responders must have reliable wireless communications, in addition to areas that have incidental coverage from transmitter sites outside of the building. It’s a fact; failure to communicate effectively puts lives at risk.  

We Have the Solution 

When RF Solutions starts a project, we begin by first consulting with the AHJ and any other known stakeholders. We identify the types of communication that may be required – internal communications between responders inside the building, and external communications to allow responders to talk back to their dispatcher. Once the specific requirements are confirmed, it is necessary to visit the actual building’s location and measure signal levels for each system to determine what enhancements (if any) are required. A 3-dimensional propagation model of the building is constructed to optimize antenna placement and determine what signal amplification is needed and where to locate the amplification equipment. Our experienced and certified engineers perform design work using iBwave software. iBwave is the global industry-standard technology for developing accurate wireless propagation. The result is an efficient design which complies with local, state, and national code requirements, and ensures that no “dead areas” will hinder effective communication. 

Leaders in the Public Safety Field

RF Solutions was founded in 2016 by experienced telecom professionals who wanted to use the best available technology and engineering services to make buildings safer and to protect critical infrastructure. Starting in the New York Metro area and branching out to adjoining states and beyond, we have received recognition for our leadership in the industry. In New York City and other locations with more stringent codes, we adhere to the established requirements and processes. In all other instances, RF Solutions takes a consultative approach because each municipality has a unique combination of first responder communications systems utilizing various frequencies and technologies. Additionally, every building has its requirements depending on the building’s construction and its location relative to transmitter sites of these systems. 

RF Solutions Serves New Jersey and Beyond 

As a result of our strict adherence to local and state ordinances, we have received many Letters of Authorization from FDNY as well as approval for numerous systems in New Jersey. Our systems are often approved on the first inspection, allowing the owners to obtain their Certificates of Occupancy without delay. RF Solutions currently has over a hundred projects underway in the Tri-State Metropolitan Area including overseeing one of the largest two-way radio projects in Manhattan and consulting on a large and complex Emergency Responder Radio Communications System in New Jersey.

FDNY’s Loss Will Be NYC’s Gain

FDNY’s Loss Will Be NYC’s Gain

Henry Nazar may not be a well-known name in the public safety private sector, but that’s all about to change. For the past four years, Henry’s played a crucial role behind the scenes, training fire alarm and electrical inspectors at the FDNY and then as an Auxiliary Radio Communication System (ARCS) inspector himself. As one of the few electrical engineers in the inspection unit, he brought a unique perspective to his team. “I provided a clear understanding of how the electrical code needed to be reflected in fire alarms.” 

A Fresh Start  

Last month, Henry resigned from the FDNY to start his new venture, Nazar Engineering. The firm’s offerings will include designing and filing ARC systems, performing pre-inspections, providing TCO affidavits and VO removals, as well as code consulting. And although he’ll now be using his background and experience to help those in the private sector, he plans to continue to work with the FDNY, to find solutions to problems, interpret code changes, and to provide insight. In this way, Henry can expand his reach, helping vendors design and implement better systems before they fail inspections. “As a professional engineer, I am excited to help the public with life safety issues and to utilize the experience gained with the years spent at the FDNY Fire Alarm Inspection Unit and the NYC Department of Building Electrical Code Committee.” 

A New Type of Collaboration

RF Solutions is excited to announce a new alliance with Nazar Engineering. Henry will play an important part in the design, submission, and filing of our proprietary ARC systems, working as an adjunct FDNY specialist. Having someone look at our projects through an FDNY lens will add another layer of security and assurance for our clients. 

A Fond Farewell

“Even though I’m leaving the FDNY, there are plans in the works for me to continue to collaborate, teach, and inform inspectors on electrical installations and code changes. It’s important for me to keep my long-standing relationships at the FDNY. The chiefs and inspectors are some of the best, and after hearing of my plans, I’ve received wonderful support.” 

We, at RF Solutions, wish Henry the best of luck! 

Why Process Is Critical When Lives Are At Risk

Posted on by rfsolutions

Why Process Is Critical When Lives Are At Risk

From Sub-Basement to the 104th Floor

When a fire alarm is activated, people rush from a building, desperate to escape. That’s when our end user, the brave members of the NYFD race inside. Providing the most robust, long-lasting, wireless two-way in-building communications systems is our company’s mission, and we take it very seriously. In New York City, new construction over seventy-five feet tall, and existing buildings undergoing a renovation of a legacy safety system require the installation of an Auxiliary Radio Communications Systems or ARCS. These systems provide in-building radio communications for the FDNY, ensuring vital connectivity between the Fire Chief in the Fire Command Center and his or her firefighters. The ARC system must function uniformly no matter where the firefighter is in the building from the sub-basement to the 104th floor.

RFS – Subject Matter Experts

That’s why RFS gets involved at the earliest stages of a building’s lifecycle, often requested by the engineering or consulting firms working on the project. They look to us as subject matter experts in the field of wireless communications. RFS will perform a complete building structure analysis to determine accurate radio frequency (RF) propagation. From there, we’ll discover the most cost-efficient antenna placement and cable routes, verifying coverage against code requirements. We’ll thoroughly review the plan with our client and installers for acceptance. Once installed, we return to the job to test the installed cable plant before commissioning, identifying any known issues or problems. Finally, we’ll commission the system as operational. 

iBwave 

iBwave is the global industry-standard technology for developing accurate wireless propagation. At RFS, we’ve raised the bar for engineered designs by using iBwave models since our inception. When we started our company, we specifically hired iBwave certified engineers that already had years of experience with the technology. We are proud to say that we are the most proficient ARCS users of iBwave, with the greatest experience in the business. We are not satisfied with providing estimates for placement of antennas, so we run propagation analysis, and provide heat maps that depict wireless coverage in a building. 

FDNY Approvals Through Teamwork

An ARCS project is a collaborative effort between a wireless system integrator, such as RFS, the electrical contractors responsible for the installation of life safety and security systems in a building, and at times the fire alarm and security company whose systems are installed simultaneously with an ARCS and follow the same strict code requirements from the Department of Buildings (DoB) and the FDNY. We take great pride in our high-level of communication amongst our strategic partners. We work together to assure a smooth and successful installation. Many of our ARCS are getting approval on the first inspection due to our eye for detail, which reduces problems and minimizes the time to completion of a project. 

Predictive Analysis Ensures Adequate Coverage

    At RFS, our ARCS pass inspections, allowing our building owners to receive their Certificate of Occupancy. We do this by using predictive analysis to ensure adequate coverage. Other companies without this level of sophistication risk not having their systems meet the stringent coverage requirements. They will try to overcome design deficiencies by turning up the power, in many cases making the situation worse. It’s always financially beneficial to do the right thing from the start; instead of taking the chance that a failed FDNY inspection delays the receipt of a Certificate of Occupancy.

‘First Do No Harm’ Applies to Installing Public Safety Systems in Hospitals Too

Posted on by rfsolutions

‘First Do No Harm’ Applies to Installing Public Safety Systems in Hospitals Too

Installing in-building wireless communication systems inside existing hospitals adds several layers of complexity and comprises some of the most challenging construction environments. The factors involved include uninterrupted patient care, significant infection risk control measures, and high levels of hygiene, which are considerably more critical in a medical facility than a commercial or residential building. These public safety installation projects require extra steps to be taken to minimize the interaction between construction activity and caregiving operations. To ensure a safe environment for their patients, nurses, doctors, and staff, hospitals have developed industry-standard project management tools such as life safety plans and physical requirements like tenting to ensure patients’ safety during construction.
 
Every Project Begins With ICRA 
Construction projects in occupied hospitals require specialized procedures and equipment as they can negatively affect patients and possibly spread infection. Before any work begins, hospitals use a system called Infection Control Risk Assessment (ICRA). It’s a roadmap a project manager follows, which delineates proactive environmental undertakings such as protective barriers, negative air pressure, dust control, and protective apparel. An Interim Life Safety Plan (ILS) is put in place to protect the safety of patients, staff, and visitors during construction activity. Every aspect of a cable installation must be reviewed in advance to identify hazards and specify preventative measures. In many cases, the setup time may take longer than the actual work itself. 
 
The Infection Control Cube aka the Popemobile
Work takes place within an infection control cube; a four-sided Plexiglas workspace often referred to as a Popemobile, which connects to ceiling tiles and contains the work and debris inside. It minimizes the possibility of patient contamination. The work takes longer to complete and is significantly more complicated than installing a system in a residential building. It takes an incredible amount of coordination, but it’s the cost of doing business in an occupied hospital. 
 
Challenges Are Not Limited to Installation
Hospitals have unique design challenges, too, as they are often constructed using concrete, steel, and low-E glass. Radiology labs use lead lining in walls, and many hospitals have subfloors, up to 60 feet below ground level. These hospital-specific characteristics can all degrade hospital communications. The age of the building and the presence of lead-lined rooms and walls result in obstructions to RF signal propagation. These factors need to be considered when designing a new system for a hospital. The reliability of in-building public safety systems is even more critical in healthcare facilities due to the confinement of its residents. 

DAS to the Rescue of the IoMT
The Internet of Medical Things (IoMT) involves connected devices used within a medical facility that allows doctors and nurses the ability to check on and monitor patients without physically being in the same room, allowing for significant increases in productivity. About 70 percent of health care organizations now utilize technology for monitoring practices. The influx of monitoring devices can put a strain on a hospital’s network, which is where the installation of a distributed antenna system (DAS) comes into play. A DAS draws in signals from a macro network and evenly distributes it using multiple antennas placed throughout a medical complex, ensuring uninterrupted service. A DAS can support various wireless carriers, making it the obvious choice for hospitals today. DAS are flexible, robust, cost-effective solutions for private enterprises. 

What Happens When the Market Lacks the Tools You Need?

What Happens When the Market Lacks the Tools You Need?

The need for reliable in-building radio coverage for first responders became imperative in the aftermath of September 11th. In the 9/11 Commission report, communication failures were a critical element that undermined the response to the attacks. The FDNY developed stringent requirements for newly constructed buildings, to support their high-rise firefighting model. Well over 100 firefighters may respond to an incident and ensuring their ability to communicate is of utmost importance. Every building has a “Fire Command Center” where the FDNY establishes onsite command and control. The newly mandated operations plan requires the installation of a wireless two-way building communications system to receive and retransmit firefighter communications throughout the building. 

What Is an ARC System?

There are three major components of an ARC System (Auxiliary Radio Communications) – the Dispatch Radio Console (DRC) at the Fire Command Center, a Radio Amplification Unit (RAU) that receives and retransmits the radio signals, and a Cable and Antenna Plant (CAP), which consists of antennas strategically placed throughout the building to ensure radio coverage. In addition to functional requirements, FDNY has established precise standards for ARC System hardware and for approval of companies and technicians who would be authorized to test and maintain these systems. 

Commitment to the Highest Standards

RF Solutions LLC launched in 2016 with a commitment to excellence in implementing in-building wireless communications systems including those for first responders. FDNY’s unique specifications meant no “off the shelf” equipment existed in the marketplace. Although a couple of companies were producing devices which did meet the published FDNY requirements, their offerings fell far short of our expectations for product design, stability, and overall quality. An entirely new system would have to be custom-designed and built for this application, and the resulting system would require proprietary software for proper operation as well as self-monitoring capabilities. We knew the only viable option was to design and produce our own ARCS equipment.

Designed and built in the USA

After making a list of what is considered to be essential system qualities beyond the basic FDNY requirements, we set out to ensure that these critical, life-safety systems would be of the highest quality and reliability. So it was not up for debate; we’d only build our products in the US by a manufacturing firm meeting ISO 9001 standard.  We decided to comply voluntarily with President Obama’s Executive Order 13636 (“Improving Critical Infrastructure Cybersecurity”) and chose to engage a certified, US-based developer.  The software development team understood that it was crucial to have a system that is easy to operate while maintaining exceptional reliability. Again, all software systems are designed and supported by us here in the US.  

Going Above and Beyond

Once we had a production-ready system, we submitted our proprietary equipment (the Radio Command Series – RAU and DRC) to a NRTL (Nationally Recognized Testing Laboratory).  Here it was certified for full compliance with UL Standard 60950-1 (“Information Technology Equipment Safety”) as well as with FCC Part 15 (“Electromagnetic Compatibility”). We are the first (and so far the only) company whose ARC System components have been tested to these specifications. Our company is always thinking ahead, and with our approach and local teams, we will be quick to meet future requirements. Modifications to the NYC code are coming soon, and we are already implementing adaptations to our equipment, ensuring our equipment leads the way with best in class solutions. 

Setting the Bar for Life Safety

As of today, RF Solutions has installed (or are in the process of installing) our Radio Command Series equipment in over 100 buildings in NYC.  We are happy to report that our systems are getting FDNY approvals, often passing on the first inspection. The decision to manufacture our products provides us with complete control, and it is the foundation of our firm’s mission: to develop and install the highest quality wireless communications system so that first responders can do their job and save lives. 

A City Full of Heroes

Posted on by rfsolutions

A City Full of Heroes

Although my title at RF Solutions is Director of Communications, I would prefer it was Chief Story Teller. I love a good story; I think most people do. Before this job, my writing experience focused on travel, culture, and global adventures. So, when an opportunity to work for a firm that installed in-building wireless solutions came about, I made sure there was a story to tell. And, after digging a little deeper, I found there were many. 

In Search of the Missing Link: an FDNY Firefighter

For the past few months at RFS, I’ve spent a great deal of time reading documentation, attending webinars, and asking a ton of questions. I wanted to ingest the world of in-building life safety systems; specifically, FDNY mandated ARCS (Auxiliary Radio Communication Systems) post 9/11. These are complex networks that require engineers with years of experience to undertake and design. As my knowledge increased, and I reached a point where I thought I was ready to write about the company’s accomplishments, it hit me. Some pretty essential people were missing from my stories: the firefighters themselves. That’s when I made it my mission to meet a few of the brave members of the FDNY. 

The Source: Facebook

I didn’t know any firefighters personally, so I went to my most trusted source: Facebook. My network hasn’t failed me yet, and I was excited to find many of my friends had connections to an FDNY firefighter. I was honored to sit and talk with two exceptional members of the force, to hear their stories, and share their wisdom. They have both been an FDNY firefighter for many years, and have seen the evolution of fireground communications. 

Bureau of Operations Deputy Assistant Chief Rich Blatus spoke to me about the changes he’s witnessed over the past four decades. He believes recent advancements in technology have led to safer environments for firefighters. 

We’ve Come a Long Way, Baby

“I started my career in 1980 as a firefighter in the Bronx. Back then, if you had a fire on the 32nd floor, they’d find a telephone number of a company located on that floor, and once upstairs, you’d use that phone to call down to the Chief Officer command in the lobby. That was the only method of solid communications available. From there we moved on to using a cross band repeater where we’d extend the range of our handheld radios by using a dual-band mobile or base radio located in the truck outside the building.”

The Days of Walkie-Talkie Relays are Coming to an End

After 9/11, there were changes made to the FDNY fire code regarding new high-rise construction 75 feet or higher, and existing buildings with fire alarm panel upgrades. A fire department fixed auxiliary radio communication system (ARCS) with multiple channel capability is now required. The days of relying on walkie-talkie relays are soon coming to an end. “I’ve been in fires in buildings with ARC systems. They are a more reliable way for firefighters to communicate in a building. I can get the information that I need to know. The code changes regarding communications are a tremendous step in the right direction. Anything that improves communications on the fireground and can help us effectively communicate our tactics, can help save lives,” said Deputy Assistant Chief Blatus. 

You Might as Well be on the Surface of the Moon

Deputy Assistant Chief Bronx Borough Commander Christopher Boyle, currently serving as Chief of Tactical Communication for FDNY, charged with coordinating and developing all tactical communication projects, and one of the writers of the ARC system fire code spoke with me about life before and after ARCS. “When fighting a fire in a building without an ARC system, as soon as you went above the 15th floor, depending on the size of the building it could happen sooner, the firefighters you are trying to communicate with might as well be on the surface of the moon. You can’t talk to them. Communication in a fire is critical, and if I can’t find out what they have or what they’re seeing – it’s very frustrating. Having an ARC system is phenomenal. It took us from having no communication to being able to talk to whoever I need to speak with.” It was an incredible opportunity to speak with one of the writers of the fire code. I had so many questions, and Chief Boyle patiently answered every one of them. Chief Boyle sits on an ARC system task force that works on continually improving the code specifications for the radio communication in-building systems. New changes to the code are expected first quarter 2020. 

Can You Hear Me Now?

It was a gift to be able to speak directly with the men who use ARC systems in their daily lives. My knowledge base expanded to include the perspective of the 32nd floor. I can see Chief Boyle and Chief Blatus picking up a 2-way radio handset and getting the information they need to make the most educated decisions. And I’m even prouder of the work we do at RF Solutions. And firefighters are modern-day warriors with the most incredible stories, and I feel privileged to have the opportunity to tell them.  

Made in the USA

Posted on by rfsolutions

Made in the USA

Three years ago, we started RF Solutions with a mandate to design and implement state of the art ARC (Auxiliary Radio Communication) System hardware and software. ARC Systems were a newly required FDNY mandate, and a quality product that met all NYC code requirements didn’t yet exist in the marketplace. We needed to manufacture proprietary equipment and software and decided to build in the US. It was the right decision, and we have no regrets; it has enabled us to drive our business very far in a short amount of time. 

Taking Extra Steps to Ensure Reliability

The specialized hardware required for Auxiliary Radio Communications (ARC) Systems deployed in New York City, provides onsite command and control communications throughout every new building. First responders in emergencies use our products when lives are on the line. Our products must be reliable at all times.  To maintain this reliability, we have taken extra steps that no one in the marketplace has taken.  Our electronics are tested in an ETL facility and meet exacting UL standards. We maintain these high standards in every system we produce. By insisting the product is built in an ISO 9001 facility, we ensure ongoing quality control, unlike our competitors that have chosen to build their products onsite at their integration job. 

We Manufacture with Integrity

At RF Solutions, we were crazed about the integrity of our manufacturer.  We selected an operator that maintained an environmentally friendly facility as well as providing extensive support for their local community. We are proud to say we found such qualities when vetting our manufacturer. Better yet, we were able to satisfy one additional mandate. The company was in America. Having a local manufacturer that is nimble has offered us significant advantages. The proximity of the plant gives us a competitive advantage because we can quickly respond to customer feedback. In Q4 we will be rolling out new upgrades to our hardware.  More information will be coming out in the next few weeks.  

Customized Options

With engineering and manufacturing resources nearby, we can develop customized solutions for special situations. Any questions or concerns are answered in real-time. We can stay ahead of upcoming code changes required by federal or local government agencies, as well as leverage advancements in technology.

Proximity to the NY Market

Manufacturing near our market allows us to schedule production and delivery to meet the challenges of changing customer timeframes. We can maintain short order lead times along with reduced cost and time for deliveries. Our products are not subject to tariffs or duties and will never get held up in customs. This rapid turnaround time gives us the ability to provide outstanding customer service.

Maintaining a Closed Network

And lastly, and maybe most importantly, we were concerned with the possibility of cyber threats if we built our products outside of the United States. Our custom control and monitoring system consist of microcontrollers and custom circuit boards, as well as proprietary software. We determined that the risk of system hackers would be minimized using local electrical and software engineering services that were ISO 9001 certified. Knowing we’ve done everything we can to ensure that our systems are 100% operational at go time was a mission-critical factor. Our systems are built to support the brave work that our first responders do to save lives. At RFS, we take our mission very seriously. 

Your ARCS Passed Inspection! Now What?

Posted on by rfsolutions

Your ARCS Passed Inspection! Now What?

As a building owner or property manager, you pray the public safety system you’ve installed will never get used. But what if it does? How can you ensure that it’ll work at go time? This “what if” is not something you’re legally allowed to leave to chance, as per the specifications in the FDNY regulations. Life safety equipment can go “Out of Service” without anyone realizing it. There is only one way to make sure that when the time comes, and you need your ARC System to work, it does. There is no substitute for regular testing and inspections, also known as Day Two Support. 

At RF Solutions, we offer our clients a complete monitoring and support package that begins the day you receive your Letter of Approval. As specified in the FDNY FC511, an approved ARC System must be operated and maintained in good working order and allows for remote monitoring and maintenance of the system. In addition, the FDNY fire code requires annual testing and fault mitigation of the system, as well. 

Maintain Systems in Good Working Order

According to NYC FDNY requirements (3 RCNY 511-01), a daily inspection of the Auxiliary Radio Communications System (ARCS) is required. At RF Solutions, we can provide a secure remote connection to the system to perform this function.  We provide a recordkeeping log at regularly scheduled intervals, no less than once a day.  If the system fails to meet the performance standards, RFS will repair or replace warranted system components to maintain FDNY standards. 

The ARC System components must be inspected and tested annually to confirm that the system is still in good working order. The certification document is then submitted to the FDNY for permit renewal. RFS performs the mandated testing and submission of the materials to the FDNY. 

Your ARC System is Five Years Old. It’s Time to Recertify. 

FDNY FC R511-01(f) requires a radio coverage survey of the system, conducted in the same manner as the commission test. The results of the five-year recertification test will be compared to the original commissioning test to determine whether there’s been any degradation to the system’s performance. Successful recertification results also require submission to the FDNY for permit renewal. RFS performs the five-year test and submits all applications for a permit renewal as directed by the FDNY. 

We Guarantee It

At RFS, we manufacture our proprietary Radio Command Series, which includes the Dedicated Radio Console (DRC) and Radio Amplification Unit (RAU).  As the manufacturer, we provide a hardware and software warranty that covers these units for repair or replacement.  This warranty begins with the initial one-year warranty included at the time of purchase and up to the 5-year recertification date.

Support Outside of NYC

Our Day Two support services work similarly outside of New York City. RFS offers testing and support for Emergency Responder Radio Communications Systems (ERRCS) regardless of its location and irrespective of who designed or installed it. A public safety system protects the public, but the protection only works if the system works. A reliable public safety support team provides a building owner with peace of mind knowing they are covered in case “as and when” becomes “911, what is your emergency?”
