VHFBRIDGE (WITHOUT.CASING)
The AJAX vhfBridge without casing is a compact PCB-only version of the wireless signaling module that connects Ajax security hubs to third-party VHF transmitters, transmitting alarms over long distances without internet dependency for remote or unstable coverage areas.
It provides the same 8 configurable transistor outputs (Contact ID/SIA protocols), Jeweller encrypted communication up to 1800m, and backup power support as the cased version but requires custom enclosure installation for production deployments.Key Specifications
