Ajax uartBridge Receiver Module for Third-Party Systems (5260)

Ajax uartBridge - Receiver Module for Third-Party Systems

uartBridge is a bare receiver board for installers and integrators who want to use Ajax wireless detectors with another security or smart home system. It receives signals from up to 85 Ajax Jeweller detectors over two-way radio and hands them to the host controller through a UART serial interface. The board runs on 5 V DC, measures 64 × 55 × 13 mm and is meant to be built into the host equipment or a suitable enclosure indoors. For a wired alarm panel with zone inputs, ocBridge Plus is the matching Ajax receiver.

Also listed as 5260. Ajax model ID UBR.Y.J.
