Surprising fact: nearly 40% of high-rise radio failures happen below grade or in stairwells, where reliable communication matters most in New York City.
When property teams search for fdny approved arcs companies, they mean a practical life-safety need: a wireless two-way building communication solution that keeps firefighters connected inside complex buildings.
We present this page as a concise service-directory guide and a technical primer. It explains how ARCS systems work, what code-driven compliance requires, and what a qualified provider does from installation to testing and maintenance.
ARCS acts as a fire protection communications layer. It ensures radio signals reach stairwells, below-grade areas, and other signal-challenged spaces during an emergency.

Why ARCS Matter for New York City Buildings and First Responders
Auxiliary radio setups bridge the gap between street-level networks and interior operations. An auxiliary radio communication system is a dedicated, wireless two-way radio link used by the fire service to send and receive portable radio frequencies inside a building.
How two-way radio coverage works
We use a transceiver or base station tied to a building-wide antenna network and a lobby console. This architecture brings the signal source closer to crews and improves indoor radio communication in real time.
Reducing dead zones in dense structures
Reinforced concrete, steel framing, elevator shafts, and mechanical rooms block or reflect signals. Those materials create stairwell, basement, and upper-floor dead zones.
A distributed antenna approach places multiple antennas where responders operate. That reduces gaps and gives measurable coverage throughout building areas that matter during an emergency.
| Challenge | Effect on Radio | ARCS Solution |
|---|---|---|
| Concrete cores | Signal attenuation | Interior antennas close to users |
| Basements & stairwells | Dead zones | Targeted antenna placement and testing |
| High-rise floors | Loss from distance | Distributed feeds and verified coverage |
- We stress engineered, tested coverage—not assumptions.
- Consistent radio links let responders coordinate evacuations, searches, and command updates.
FDNY and NYC Code Requirements for Auxiliary Radio Communication Systems
Local law ties system obligations to specific legal anchors. NYC Building Code Section 917.1.2 and Fire Code FC 511 require that auxiliary radio systems be installed, acceptance tested, commissioned, and maintained for use by the fire department.
We stress that the requirements extend beyond initial installation. Owners must support ongoing testing, recordkeeping, and prompt repairs so the system remains in service throughout building operations.
Which buildings and how the system is used
Typical triggers include high-rise buildings and any structure with known dead zones, often those 75 feet or taller. The system serves stairwells, basements, lobbies, and other areas where portable radio signals fail.
What inspectors look for
Inspectors verify measurable signal strength, reliable power and battery backup, and complete documentation of commissioning and maintenance.
| Inspection Area | What is checked | Typical evidence |
|---|---|---|
| Signals | Floor-by-floor coverage and strength | Test reports, heat maps |
| Power | Primary feed and battery backup performance | Runtime test, battery records |
| Documentation | Acceptance and maintenance records | As-built drawings, commissioning logs |
- Acceptance testing means formal verification against pass/fail criteria with FDNY-facing documentation.
- Noncompliance can delay sign-off, affect occupancy timelines, and create liability for owners.
fdny approved arcs companies: How to Choose the Right Provider
Choosing the right vendor affects safety, timing, and long-term compliance for any high-rise project. We focus on firms that pair field competence with clear, inspection-ready deliverables.
FDNY approval and technician qualifications for compliant work
Verify credentials first. Ask for technician certifications, proof of acceptance testing experience, and documented commissioning records. These items show the provider knows code requirements and acceptance criteria.
Engineering and design capabilities for coverage mapping
Good teams model and map coverage. They set measurable performance goals, place antennas strategically, and validate floor-by-floor signal strength in stairwells and below-grade areas—not just easy spots.
Experience coordinating with the AHJ for permits and acceptance
Ask how contractors handle permits, scheduling, and site access. Experienced firms prepare inspection packets, coordinate with the AHJ, and reduce surprises during acceptance testing.
“We recommend bids that include scope, testing methodology, timeline, assumptions, and a plan for ongoing services.”
- Checklist: credentials, engineering deliverables, acceptance plan, permit coordination.
- Also ask: how they interface with fire alarm and other alarm workflows to avoid conflicts in rated spaces.
ARCS System Components You Should Expect in a Compliant Installation
A compliant auxiliary radio installation combines hardware, routing, and protected spaces to deliver predictable in‑building coverage.
Base station, amplification, and control circuitry
At the heart of the system is a base transceiver that ties the outside radio source to interior equipment. We expect radio amplification hardware and control circuitry to manage gain, isolation, and alarms.
Control boards handle channel switching and fault reporting so technicians can verify performance during acceptance testing.
Distributed antenna network: antennas, cabling, and rated pathways
A practical antenna system places small antennas near stairwells, lobbies, and basements to reduce dead zones. Routed cabling must follow rated pathways and avoid conflict with other life‑safety wiring.
Good designs document antenna locations, cable lengths, and feed points for repeatable testing and maintenance.
Lobby console and protected equipment rooms
We expect a dedicated radio console in the lobby for responder access and a fire‑rated equipment room for critical electronics. Protected locations improve survivability and uptime during a fire or outage.
Power continuity is part of the installation. Backup power and battery runtime records should be listed in every proposal.
- Clear line items: base station, amplifiers, antennas, cabling, console, and power.
- Outcomes: fewer dead zones, reliable radio communication, and streamlined inspections.
| Component | Role | Inspection evidence |
|---|---|---|
| Base transceiver | Signal source and control | Commissioning report |
| Distributed antennas | Floor and stairwell coverage | Heat maps and test logs |
| Lobby console & power | Responder access and continuity | As‑built drawings, battery tests |

Installation, Testing, Commissioning, and Ongoing Maintenance Services
A clear lifecycle plan starts with a hands-on site survey that records signal levels where responders work.
Site evaluation and floor-by-floor verification
We verify signals on every floor and in each stairwell to find weak spots before design work begins.
This testing documents real coverage gaps and informs power and antenna placement requirements.
System design and documented deliverables
Our design files show antenna layout, coverage goals, and power requirements so the system meets performance targets.
Design deliverables include heat maps, cable routes, and a bill of components for inspection records.
Professional installation and integration
We install equipment with careful pathway planning and workmanship that respects fire alarm and life‑safety interfaces.
Coordination avoids conflicts in rated spaces and preserves the integrity of other alarm systems.
Commissioning, acceptance testing support, and certification
Commissioning validates the installation against the design and prepares the project for formal acceptance testing.
We provide repeatable test methods, clear reports, and on‑site support during AHJ acceptance to streamline certification.
Ongoing maintenance and periodic recertification
After acceptance, annual inspections and periodic recertification keep the system in service and compliant.
Preventive maintenance covers battery checks, component testing, and performance troubleshooting to reduce failure risk.
“A single accountable provider for installation, testing, and maintenance reduces record gaps and speeds resolution.”
| Service | Typical Activity | Inspection Evidence |
|---|---|---|
| Site evaluation | Signal surveys on floors and stairwells | Heat maps, logs |
