Ajax vhfBridge

Instant alarm transmission without Internet

vhfBridge is a transponder that provides a hub with an additional channel to communicate with an armed response company.

With vhfBridge, you can use Ajax systems where the Internet connection is unstable or if your preferred armed response is not Ajax ready.

Alarms and events of the system are transmitted via VHF radio waves over tens of kilometres1. vhfBridge can be used as a primary or a backup communication channel.

Elaborate autonomy – up to 75 hours battery backup

You can add a 7a/h 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

  • Up to 75 hours of autonomous operation
  • Place for a 7 Ah backup battery


Adjustable signalling

Get only events you need. You can configure each vhfBridge output in the Ajax app: set an event or disable it.
