Marconi Technologies, a New York manufacturer of in-building emergency communication equipment, announces a numbered milestone in fire alarm arc system units shipped to New York City buildings since its founding.
NEW YORK, NY — Marconi Technologies, a Manhattan-based manufacturer of in-building emergency communication equipment, announced that it has reached a milestone in the number of fire alarm arc system units it has shipped to buildings across New York City since the company was founded. The milestone covers units manufactured in the United States and delivered to high-rise properties that are subject to Fire Department of the City of New York (FDNY) requirements. The company said the figure reflects its sustained focus on the city’s local market.
An arc system, short for Auxiliary Radio Communication System, is an in-building radio installation that gives fire personnel a dedicated channel for communicating inside large structures. In New York City, the FDNY has specified this type of system for many high-rise buildings, where dense steel and concrete construction can interfere with portable radio signals. Municipal fire departments elsewhere in the New York metropolitan region have also adopted site-specific communication requirements for certain buildings.
Marconi Technologies designs, engineers, and produces its fire alarm arc system units at its own facilities rather than reselling equipment made by other firms. The company’s product line includes the RC-108A, which incorporates active antenna monitoring and carries UL Listing under the 2524A standard, and the VC-121N, a compact dual-channel unit that supports P25, a digital radio standard used by public safety agencies. A dedicated radio console with a seven-inch touchscreen, the CMD-V1, is also part of the line.
The company has also built custom units for municipal fire departments in the region, including the NR-911V for the New Rochelle Fire Department and the VC-911YK for the Yonkers Fire Department. In addition to manufacturing, Marconi Technologies provides engineering and design work, antenna propagation studies, and as-built and shop drawings. It also offers installation guidance, commissioning support, and around-the-clock technical assistance, and it holds FDNY certification to test and commission these systems.
“Reaching this number of units in New York City buildings reflects years of work with building owners, fire safety directors, and the FDNY,” said the Owner of Marconi Technologies. “We wanted to mark the milestone publicly because every unit represents a building where responders have a dedicated communication channel, and it shows how much of our engineering and production effort has been directed at this city.”
