PRODUCT DETAILS
The Ajax vhfBridge is a transponder that provides a hub with an additional channel to communicate with a monitoring station. With vhfBridge you can use Ajax systems located where Internet connection is unstable.
The device is powered from 100-240V~ mains and can be operated from a 12V⎓ backup battery.
The vhfBridge operates as part of the Ajax security system by connecting via the Jeweller secure radio communication protocol to the hub. The hub communication range is up to 1800 meters without obstacles.
The communication channel with the CMS created using vhfBridge can be used as the only or as a backup channel for communicating with the CMS (more reliable option). This means that the hub can simultaneously transmit all events and alarms to the monitoring station of the security company not only through SIA (DC-09), ADEMCO 685, SurGard (Contact ID), and other proprietary protocols but also using vhfBridge.
The transponder receives information about alarms and events from the hub via the Jeweller radio channel. vhfBridge then transmits it to a third-party VHF transmitter over the wires. The VHF transmitter, in turn, transmits all events and alarms to the CMS via a radio channel.
