VHFBRIDGE (WITH.CASING)
The AJAX vhfBridge is a wireless signaling module that connects Ajax security hubs (Hub 2, Hub Plus, Hub 2 Plus, Hybrid) to third-party VHF transmitters, providing reliable alarm transmission over tens of kilometers via VHF radio waves—ideal for areas with unstable internet like remote sites, mountains, or reserves.
It features 8 configurable transistor outputs (high/low potential, pulse/bistable modes) for Contact ID/SIA protocols, tamper protection, Jeweller two-way encrypted communication up to 1800m range, and backup power support with automatic notifications for jamming or failures.Key Specifications
