Overview
Give command, crew and dispatch instant communication with each other when crucial seconds count. The FHW505 uses the latest DECT7 wireless technology to connect your crew in the apparatus and on scene. New Stereo Listen-Through microphones provide situational awareness and face-to-face communication without removing your hearing protection. Directly connect any portable radio with a PR interface cable (sold separately). Improved voice clarity, advanced hearing protection and a “set-and-forget” automatic noise gate make the FHW505 an indispensable communication and safety tool.
