Manufacturer overview

Wireless module for connecting an Ajax system to third-party VHF transmitters

Instant alarm transmission without Internet. 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 in cities where Internet connection is unstable, in nature reserves, mountain and desert areas.

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.

Adjustable signalling. Get only events you need. You can configure each vhfBridge output in the Ajax app: set an event or disable it.

Unique wireless technology. Jeweller is Ajax’s proprietary radio protocol for secure two-way communication. It provides block encryption and device authentication during each communication session with an Ajax hub or radio signal range extender. Jeweller prevents sabotage, spoofing, and data theft.

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.

Technical information. In an Ajax system, you can combine devices of all product categories: Intrusion protection, Video surveillance, Fire and life safety, or Comfort and automation. Create the system to suit your needs and manage it in a single interface.
