Description Ajax vhfBridge White - Module for connecting Ajax security systems to third-party VHF transmitters
Elaborate autonomy You can build in a 7 Ah backup battery inside a vhfBridge casing. It will feed a VHF transmitter with up to 2A current consumption. Therefore, the transmitter doesn't need to have a separate battery, which makes maintenance less frequent. In case of a power outage at a facility, the transponder and the transmitter operate on a backup battery for up to 75 hours4 while still transmitting events to a central monitoring station. Hassle-free installation Similar to other Ajax devices, vhfBridge connects to a hub in the app by scanning a QR-code. The transponder casing has perforated areas for more organized wiring. Outputs are configurable with Ajax apps for smartphones and computers.
