Product Information


The Radio-To-Intercom Bridge receiver is designed to interface to an existing wired Public Address Intercom system and allow PA or intercom announcements using your Analog or DMR Digital two-way radio. Each model can operate on VHF LMR business band, UHF LMR business band, or VHF MURS 2-way radios, and can work through radio repeaters.

Wireless technology provides a cost-effective and flexible way to provide Public Address / Mass Notification coverage across your entire facility or to isolated pinpoint locations.
