Ajax vhfBridge Black

The Ajax vhfBridge Black is a transponder that provides a hub with an additional channel to communicate with a monitoring station. The Ajax vhfBridge is a module for connecting Ajax security systems to third-party VHF transmitters/armed response radio transmitters.

The vhfBridge enables the use of Ajax systems in areas with an unstable or no Internet connection, such as nature reserves, mountainous and desert regions. Alarms and events of the system are transmitted via VHF radio waves over a vast distance. The vhfBridge can be used as a primary or a backup communication channel.

You can add a 12V 7ah/7.2ah/8ah backup battery inside a vhfBridge casing which can also power up the armed response radio transmitter. In the event of power failures, the vhfBridge and AR Radio Transmitter will continue operating for up to 75 hours.

Compatible with Hub 2, Hub Plus, Hub 2 Plus, ReX and ReX 2. vhfBridge does not work with Hub, ocBridge Plus, uartBridge and third-party security control panels.
