New York DAS Installer Network — ERRCS & Cellular Coverage
Public-safety radio coverage your fire marshal will sign off on, and cellular coverage your tenants will stop complaining about — surveyed, engineered and installed by licensed New York DAS crews statewide.
- ERRCS / public-safety DAS
- Cellular DAS (carrier-grade)
- RF benchmark surveys
- BDA and fiber DAS head-ends
- NFPA / IFC code compliance
- AHJ acceptance testing
Two very different problems get solved by antennas in ceilings, and it pays to keep them straight. ERRCS — the Emergency Responder Radio Communication System, often called public-safety DAS — exists so firefighters' and police radios work in your stairwells, basements and interior corridors, and it's mandated by fire code for many buildings. Cellular DAS exists so your tenants' phones work, and while no code requires it, leasing agents will tell you dead zones show up in renewal conversations. Low Voltage New York scopes both across New York State and matches each project with partner crews that hold the right certifications for the system and the jurisdiction.
The code pressure is real and growing. Modern building and fire codes — following IFC Section 510 and NFPA standards — require minimum in-building radio coverage for emergency responders, typically demonstrated floor by floor, with critical areas like stairwells, fire command centers and elevator lobbies held to a stricter standard. New York City goes further, requiring Auxiliary Radio Communication (ARC) systems in new high-rise construction with FDNY plan approval and acceptance testing. Elsewhere in the state, county and municipal AHJs enforce their own versions, usually triggered at permit time for new construction, major renovations, or a change of occupancy.
Whether you're a developer who just got flagged at plan review, a property manager with a violation notice, or an owner getting ahead of the requirement, the path is the same: benchmark survey, engineered design, installation, and acceptance testing with the AHJ. We manage it end to end.
ERRCS and public-safety code compliance
An ERRCS project starts with an RF benchmark survey: technicians walk the building with calibrated equipment and measure existing public-safety radio signal on the frequencies your county's first responders actually use. If coverage falls short of the code threshold, the fix is an engineered system — a donor antenna on the roof, a signal booster (BDA) or fiber-fed head-end, and a distributed antenna network sized to bring every required area up to signal. Code typically demands high coverage percentages in general areas and stricter coverage in critical areas, along with survivability requirements: two-hour fire-rated enclosures or pathways for key components, NEMA-rated equipment, battery backup, and annunciation to the fire alarm panel.
Partner crews design to the local AHJ's amendments — which vary meaningfully between, say, FDNY's ARC rules in New York City and a county fire coordinator's requirements upstate — and carry the FCC licensing coordination with the frequency license holder that BDA deployments legally require.

Cellular DAS systems for tenant coverage
Cellular DAS solves a business problem instead of a code problem: modern glass, LEED-driven low-E coatings, concrete and below-grade space kill carrier signal, and tenants judge the building on their phones' bars. Solutions range from carrier-approved signal boosters for mid-size buildings to full multi-carrier DAS with dedicated head-end equipment for towers, campuses and venues. The economics differ from ERRCS too — carrier participation, rebroadcast agreements and equipment tiers shape the budget, and we'll be straight with you about which class of system your square footage and tenant profile actually justify.
Every cellular deployment includes the carrier coordination that legality requires: rebroadcasting a carrier's licensed spectrum needs their sign-off, and reputable integrators handle that paperwork rather than quietly skipping it.
From survey to acceptance testing
DAS projects fail at handoff points, so we manage the full sequence: benchmark survey and report, engineered design submitted for AHJ or carrier review, installation coordinated with the GC or building operations, commissioning, and the final walk test — often grid-by-grid with the fire marshal present for ERRCS. You get the survey data, design documents, test results and licensing paperwork as a package, which matters again at every annual retest.
Speaking of which: ERRCS isn't install-and-forget. Codes require periodic testing and the AHJ can demand proof, so we set up the recertification schedule before closeout instead of leaving it to the violation notice.
What a New York DAS installer actually delivers
Searching for a New York DAS installer usually means one of two triggers: a plan review or certificate-of-occupancy hold on emergency responder radio coverage, or tenants and clinical staff reporting dead zones that leasing and operations can no longer ignore. The right installer owns the full sequence — RF benchmark survey on the frequencies that matter, engineered design, pathway and head-end install, carrier or AHJ coordination, and a documented acceptance test — not just hanging antennas after someone else guessed at coverage.
Low Voltage New York is not a single shop swinging ladders under one license. We scope the building, then match you with partner DAS crews that already work your jurisdiction's rules: FDNY ARCS process in New York City, county fire coordinator criteria on Long Island and upstate, and carrier rebroadcast agreements on cellular systems. That matching step is how a statewide network beats a generalist electrician who treats DAS as a side skill.

FDNY ARCS vs statewide ERRCS
In New York City, new high-rise construction and many major alterations trigger Auxiliary Radio Communication System (ARCS) requirements under the Building Code and FDNY Fire Code rules — a dedicated Fire Department radio path with its own plan approval, commissioning test, and certificate-of-fitness supervision. Elsewhere in the state, Emergency Responder Radio Communication Systems (ERRCS) are driven by the Fire Code of New York State Section 510 and the local AHJ's amendments. Same problem class, different paperwork and acceptance rituals.
We keep the two tracks separate in scoping so budgets and schedules reflect the authority that will actually sign the system.

FAQ
DAS & ERRCS Installation — Common Questions
Does my building actually need an ERRCS?
It depends on your jurisdiction, building size, construction type and occupancy — the trigger is usually new construction, substantial renovation or change of occupancy, at which point the AHJ requires proof of in-building responder radio coverage. In New York City, new high-rises must install ARC systems under FDNY oversight. The honest first step is a benchmark survey: if your building already meets coverage thresholds, you may need documentation rather than a system, and we'll tell you which.
What does a DAS or ERRCS installation cost?
Square footage, construction type and required coverage drive it. A single BDA with a modest antenna network in a mid-size building is a very different project from a fiber-fed system in a concrete tower with two-hour rated pathway throughout. Survivability requirements — rated enclosures, battery runtime, annunciation — add real cost to ERRCS that cellular systems don't carry. We survey first, then quote from measured data instead of assumptions.
Who signs off on an ERRCS, and what does acceptance involve?
Your local authority having jurisdiction — FDNY in New York City, typically the fire marshal or county fire coordinator elsewhere in the state. Acceptance usually means a grid-based walk test demonstrating required signal strength in general and critical areas, verification of survivability features like battery backup and rated enclosures, and confirmation of alarm panel annunciation. We schedule and attend the acceptance test and deliver the documentation package the AHJ keeps on file.
Do carriers have to approve a cellular DAS?
Yes — rebroadcasting a carrier's licensed spectrum requires their consent, formalized in a rebroadcast or retransmission agreement, and larger systems involve carrier engineering review of the design. Timelines for carrier approval vary and can be the longest item on the schedule, so we start that coordination at design time. Skipping it isn't an option we offer; unauthorized rebroadcast creates FCC exposure for the building owner.
How long does an ERRCS project take from survey to sign-off?
The survey and report are quick — typically a couple of weeks including scheduling. Design, AHJ review, equipment procurement and installation follow, with total timelines commonly running a few months depending on building size, AHJ review queues and equipment lead times. If you're facing a certificate-of-occupancy deadline, tell us the date up front: sequencing the AHJ submittal early is the single biggest schedule lever.
What is a DAS system?
A DAS (Distributed Antenna System) is a network of spatially separated antenna nodes connected by fiber or coax to a central signal source, designed to distribute cellular and radio signals throughout a building or campus where outdoor signals can't penetrate. Large concrete-and-steel structures — high-rises, hospitals, stadiums, underground garages, warehouses — block RF signals, creating dead zones for both cell phones and public-safety radios. A DAS solves this by capturing signal from donor antennas or carrier feeds and rebroadcasting it through indoor antennas on every floor. There are two types: cellular DAS (improves cell coverage for tenants, requires carrier approval) and public-safety DAS/ERRCS (ensures first responders' radios work inside, mandated by fire code).
What is a distributed antenna system and how does it work?
A distributed antenna system works by taking a signal source — either an off-air donor antenna on the roof, or a direct carrier feed via fiber — and distributing it through a network of remote amplifier units (RAUs) to indoor antennas placed throughout the building. The system actively amplifies and balances signal so that coverage is uniform across all floors, not concentrated near windows. In a typical installation, fiber runs from the head-end equipment room to RAUs on each floor, and coax or plenum-rated cable connects each RAU to several ceiling-mounted antennas. The result is that a phone or radio works the same in the core of the building as it does near a window.
How do I choose a New York DAS installer?
Ask who performs the RF survey, who engineers the system, who holds the relationship with the AHJ or carriers, and who shows up for acceptance testing. A qualified New York DAS installer can name the frequencies and code path for your building type — FDNY ARCS in NYC high-rises, Section 510 ERRCS elsewhere — and will not skip donor coordination or survivability details to win the bid. Request a free estimate and we match a licensed DAS crew from our network that already works your region.
What is the difference between FDNY ARCS and ERRCS?
ARCS is New York City's Auxiliary Radio Communication System framework for Fire Department in-building radio, with FDNY plan approval and commissioning rules. ERRCS is the broader emergency responder radio coverage concept used in state fire code (Section 510) and many suburban/upstate jurisdictions. Both exist so first-responder radios work in stairwells, basements, and deep floor plates; the filings, test agents, and hardware details differ by AHJ.
Do you install DAS in New York City high-rises?
Yes. Our network includes NYC DAS crews experienced with high-rise pathway, building-management logistics, and the FDNY ARCS approval track alongside cellular DAS for tenant coverage.
