The New York City Building Code requires that an in-building auxiliary radio communication (ARC) system be installed and maintained in all newly‑constructed high-rise buildings.  An ARC system is a wireless two-way building communication system for Fire Department use only that receives and transmits Fire Department portable radio frequencies within the building.  An ARC system typically consists of a transceiver (base station) connected to a building-wide antenna system, with a radio console in the building lobby. Please reach out to Captain Fire Protection for the design, installation, operation, and maintenance of ARC systems, including the testing necessary to confirm that the ARC system is providing adequate radio coverage in the building in all areas accessible for firefighting operations.
