Overview
The Ajax ocBridge Plus is a receiver module that lets a wired or hybrid alarm panel use Ajax wireless detectors. It receives the detectors’ Jeweller radio signals and presents each one to the panel as a conventional wired zone, so an existing panel in a home, shop or office can be extended with wireless detectors without replacing it.
Is it right for you?
- Choose it to add Ajax wireless detectors to a wired or hybrid alarm panel you already have.
- It handles up to 99 detectors across 8 security areas and 4 service areas, with NO, NC, EOL and 2EOL loop types.
- If you want an Ajax system with the Ajax app, you need an Ajax hub instead.
- For software integration into a panel or smart home controller over a serial link, see the uartBridge.
