uartBridge — is the module for integration with third-party wireless security and smart home systems.
A wireless network of smart and secure Ajax detectors can be added to a third-party security or smart home system through the UART interface. The module has a WH-4 connector (4-pin plug) on the board and requires a matching HU-4 connector (4-pin socket) for the wire-to-board connection.
Connection to Ajax hubs is not supported.
Supported devices:
- MotionProtect Jeweller
- MotionProtect Plus Jeweller
- DoorProtect Jeweller
- Ajax SpaceControl Jeweller
- GlassProtect Jeweller
- CombiProtect Jeweller
- FireProtect Jeweller
- FireProtect Plus Jeweller
- LeaksProtect Jeweller
Integration with third-party detectors is implemented at the protocol level.
