Surprising fact: nearly 30% of high-rise incidents see critical signal gaps inside key zones, slowing response and risking lives.
We introduce what an fdny auxiliary radio communication system does for New York life safety and why building owners assess it for public preparedness. This service boosts in-building RF coverage so incident teams can coordinate clearly when conditions are chaotic and time-sensitive.
We explain why coverage fails, how ARCS works, what codes and permits typically require, and which components are involved. We position Marconi Technologies at 55 Broadway, 3rd floor, New York, NY 10006 with inspections-ready documentation and a local contact at (212) 376-4548.
Our goal is simple: deliver dependable in-building performance that helps emergency teams maintain clear coordination at the fire command location and reduce gaps in critical areas.

Why in-building radio coverage fails during emergencies in New York
During an emergency, dense building materials can turn dependable signal paths into dead zones. “When crews enter stairwells and basements, their handhelds can go silent — and that silence costs time.”
How concrete, glass, and metal weaken signals
Concrete, coated glass, and steel absorb or reflect radio signals. Mechanical rooms and elevator shafts make unpredictable reflections. These factors create pockets where in-building radio performance drops dramatically.
What an auxiliary radio communication solution is designed to do
We design an engineered distribution approach to strengthen and redistribute RF so hand-held devices can transmit and receive reliably. The goal is consistent two-way communications throughout the structure, not just on the roof.
Who relies on reliable two-way communications inside buildings
First responders, building security, engineers, and maintenance crews depend on continuous communication during fire or other incidents. Improving coverage is both a safety step and a permit-driven requirement in New York.
“Address signal loss with an engineered in-building distribution approach rather than hoping handheld radios ‘push through’ structure attenuation.”
FDNY auxiliary radio communication system: what it is and how it works
A focused distribution strategy turns a strong rooftop signal into reliable coverage on every floor.
What we install is an engineered in-building solution that receives tactical channels, amplifies them, and delivers consistent coverage where first responders operate. The RPT-1 Repeater Cabinet (RAU) handles receipt and transmit of Tactical Channel 11 and Channel 12 and links to the ARCS-2000 OC-1 Operator Console for station-level control.
How ARCS supports tactical channels for first responders
We tune the design to the channels crews use during search, evacuation, and fire attack. That means clearer transmit and receive performance across floors and in critical areas.
Radio frequency amplification and distribution
Signal is received from outside, conditioned, and amplified. Then the energy is routed through a controlled path of antennas and cabling so coverage is predictable rather than random.
In-building vs. rooftop: where performance is won or lost
Rooftop strength alone does not ensure interior success. Stairwells, basements, and core interiors commonly cause loss points without an engineered distribution plan.
“Design, installation, and testing matter as much as the hardware for predictable results.”
| Component | Role | Operational Benefit | Location |
|---|---|---|---|
| RPT-1 Repeater Cabinet (RAU) | Receive/transmit tactical channels | Reliable channel handover and power | Equipment room / closet |
| ARCS-2000 OC-1 Console | Operator interface at the command station | Centralized monitoring and control | Fire command station |
| Distributed Antenna Array | Spread conditioned RF across the building | Consistent coverage in stairwells and basements | Floors, shafts, and cores |
Code, permitting, and requirements for ARCS in high-rise buildings
Permits, inspections, and local codes often dictate when an in-building booster must be added to high-rise properties.
When local ordinances and public safety permits trigger installation
In New York, ARCS installation is frequently driven by ordinance reviews, site inspections, or public safety permits. A new permit or a renovation can prompt a building review and an expectation to fix coverage gaps.
Emergency Responder Radio Coverage (ERRC) compliance considerations
ERRC compliance requires documented proof that required areas meet acceptable performance. We test, record results, and provide inspection-ready reports so the authority having jurisdiction can close the loop.
Aligning ARCS, fire alarm interfaces, and life safety expectations
Integration matters. We coordinate power, supervision, and alarm interfaces so the installed solution meets fire alarm and life safety requirements without surprises.
Construction and renovation scenarios that commonly require an upgrade
- Major tenant fit-outs or lobby/core renovations
- Infrastructure modernization that changes RF paths
- New certificates or permit-driven remodels
“Early evaluation reduces rework, schedule delays, and inspection surprises late in the project.”
Risk management takeaway: Compliance-driven communication systems lower the chance of loss during a fire event and help protect occupants and response teams. We recommend early assessment and coordinated design to meet codes and requirements without project delays.
Core ARCS components we design and install
We assemble engineered components so command staff get consistent connections where it matters most.
Our approach breaks the architecture into clear, inspectable pieces so owners know what they buy and where it is placed.
OC-1 Operator Console for organized incident communications
The Firecom OC-1 Operator Console sits at the fire command station. It streamlines message flow and supports coordinated incident control.
We mount the OC-1 in OC-1BBxx enclosures that provide neat PEMs and standoffs for clean wiring and inspection-ready presentation.
RPT-1 Repeater Cabinet (RAU) for receiving and transmitting tactical channels
The RPT-1 is a NEMA-4 RAU housing RF amplifiers. It facilitates receipt and transmission for TAC Channel 11 and Channel 12 and adds supervised paths to reduce silent faults.
Distributed antenna layout for consistent coverage
Planned antenna spacing, shaft pathways, and floor placement give predictable coverage across stairwells, basements, and cores.
We design the antenna array to eliminate ad hoc signal bleed and to lower dead-zone risk during a fire response.
Equipment enclosures and integration hardware
OC-1BBxx enclosures are 16 gauge cold-rolled steel with a black baked finish. They accept the OC-1, RIB-1, and RCP-1 for a tidy, durable installation.
- Predictable results: supervised connections and quality enclosures reduce surprise failures.
- Inspection ready: layout and documentation match authority expectations.
- Complete scope: we deliver console, RAU, antenna layout, and integration hardware as one coordinated package.
Our ARCS services for buildings across New York City
We perform a building walk-through to map weak spots, document dead zones, and gather signal readings for a clear remediation plan.
On-site evaluation
We survey stairwells, basements, cores, and tenant spaces to pinpoint where handhelds lose contact.
Deliverable: floor-by-floor reports with measured loss points and recommended interventions.
Design for high-rise challenges
We translate findings into a tailored plan for tall buildings where vertical penetration and dense cores cause failures.
Our designs balance performance, inspection needs, and maintainability.
Installation and coordination
We schedule installations with building teams and fire alarm contacts. This reduces shutdown windows and avoids surprises.
Testing, commissioning, and documentation
We verify performance with on-site tests and provide inspection-ready records that list what was installed, where, and how it performed.
Maintenance and monitoring
Ongoing service: regular checks, supervised fault reporting, and timely replacements to prevent surprise outages.
Monitoring options show system state and faults so staff can act before an emergency reveals issues.
“Proactive maintenance and clear documentation save time, reduce re-tests, and keep responders connected when it matters.”
