Overview
The Ajax uartBridge is a receiver board that lets a third-party alarm panel or smart home controller use Ajax wireless detectors and key fobs. It receives the detectors’ Jeweller radio signals and hands them to the host system over a wired UART serial interface. It is a component for manufacturers and integrators building Ajax detectors into their own systems, not a finished device for a home.
Is it right for you?
- Choose it if you build or integrate a wired alarm panel or smart home system and want it to receive Ajax detectors directly.
- It handles up to 85 detectors.
- If you want Ajax detectors to appear as ordinary wired zones on an existing panel, the ocBridge Plus does that without software integration.
- For a complete Ajax alarm with an app, you need an Ajax hub rather than this module.
Key features
- Receives up to 85 Ajax detectors over Jeweller radio, with two-way communication up to 2,000 m in open space.
- Supported devices: MotionProtect, MotionProtect Plus, CombiProtect, DoorProtect, FireProtect, FireProtect Plus, LeaksProtect, GlassProtect and SpaceControl key fob.
- Alarm signals delivered in 0.15 s.
- UART interface to the host system.
- Block encryption based on the AES algorithm, jamming detection and protection against spoofing.
- Detector polling period adjustable from 12 to 300 s.
- Runs on 5 V DC.
- Bare board, 64 x 55 x 13 mm, 32 g, for indoor fitting inside the host enclosure.
What else you need
A host alarm panel or controller with a UART interface and firmware written to talk to the uartBridge.
A 5 V DC supply from the host.
Ajax detectors from the supported list.
Installation
An integrator or the host system’s developer fits it inside the host enclosure, connects the UART and 5 V DC lines and implements the protocol in the host firmware.
Before you buy
Only the listed Ajax devices are supported.
Rated from -10 to 40 °C and up to 90% humidity, indoors only.
The box holds the uartBridge board only.
