Marconi Technologies clarifies how FDNY ARCS approved installations differ from BDA systems used elsewhere, addressing NYC-specific fire code requirements for building owners.
-- NEW YORK, NY — Marconi Technologies, a Manhattan-based manufacturer of in-building emergency communication systems, is publishing guidance this week explaining how FDNY ARCS approved installations differ from bi-directional amplifier systems required in most other American cities. The clarification is intended for property managers, fire safety directors, and developers navigating New York City's distinct code requirements for high-rise buildings. The distinction matters because a system that satisfies fire code in another jurisdiction will not necessarily meet FDNY standards for auxiliary radio communication.
Most municipalities across the country rely on bi-directional amplifiers, sometimes called BDA or ERCES systems, to strengthen emergency responder radio signals inside large structures such as hospitals, malls, and office towers. New York City takes a different approach for many high-rise buildings, requiring an Auxiliary Radio Communication System, or ARCS, that is engineered specifically around FDNY's operational protocols and the city's dense concrete-and-steel construction. Building compliance officers who assume national BDA standards apply uniformly can face delays during inspection, a risk that has grown as more commercial towers undergo life-safety system upgrades.
ARCS installations differ from typical BDA setups in several respects, according to Marconi Technologies. Where BDA systems primarily amplify existing radio frequencies across UHF, VHF, 700MHz, and 800MHz bands, FDNY-approved ARCS configurations establish dedicated, resilient communication channels intended to function independently during emergencies, with monitoring requirements tailored to FDNY's testing and commissioning procedures. These systems must also pass inspection protocols specific to the department, which can include active antenna monitoring and documentation standards not universally required elsewhere.
Marconi Technologies manufactures both categories of equipment domestically, including ARCS models built for FDNY jurisdiction as well as BDA systems used in markets outside New York. The company said its engineering team works directly with authorities having jurisdiction, including FDNY, to track code updates and testing requirements as they evolve. Its product line includes systems with active antenna monitoring capability, along with dedicated radio consoles used during commissioning and ongoing system checks in FDNY-regulated buildings.
“Building owners outside New York are often surprised to learn that a BDA system compliant in their city would not satisfy FDNY requirements here,” said the Owner of Marconi Technologies. “Clarifying that distinction upfront helps compliance teams avoid inspection delays and unnecessary redesign work.”
