Instant alarm transmission without Internet
vhfBridge is a transponder that provides an Ajax 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 / does not have the Ajax software installed on their servers.
vhfBridge can be used as a primary or a backup communication channel.
Elaborate autonomy - up to 75 hours battery backup
The vhfBridge casing has been designed to accommodate a 7Ah battery which can also be used to 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.
