RF Receiver Ajax uartBridge Smart Home 868 MHz Black Grey

The Ajax uartBridge Smart Home RF Receiver operates on the 868 MHz band and is intended for integration of Ajax wireless detectors into wired security systems and smart home solutions. Its compact housing (55 mm x 13 mm x 64 mm) and 5 V input voltage allow installation inside the enclosure of wired control panels and hubs. The device receives radio signals from compatible Ajax detectors and forwards event information to the host system so the central unit can process alarms and status updates.

Advantages

The uartBridge provides a simple method to bridge Ajax wireless devices with wired control systems via a UART interface, enabling flexible configuration and custom integrations. Its small form factor supports discreet installation inside existing control units without requiring additional mounting space. Operating at 868 MHz ensures stable connectivity with devices designed for that frequency band, while the 5 V power input fits standard electronics inside control panel enclosures.

Suitable for

• Integrating Ajax wireless detectors with wired alarm control panels
• Adding Ajax sensors to smart home hubs that accept internal receiver modules
• Custom home automation projects that require a compact RF receiver module

Key specifications

• Operating frequency: 868 MHz
• Dimensions: 55 mm × 13 mm × 64 mm
• Power input: 5 V DC
• Interface: UART for device configuration and data exchange
• Color options: black and grey

How to use

Install the uartBridge inside the enclosure of the wired central unit or hub where it will be connected to the host’s UART port and 5 V power supply. After physical installation, configure the module through the UART interface according to the integration requirements of the control panel or hub. Pair Ajax wireless detectors with the receiver so that detector events are relayed to the central unit, which will then raise alarms or update system status as configured.

Recommendations

Place the receiver inside the control unit away from large metal objects or sources of electromagnetic interference to preserve radio signal quality. Verify UART pinout and power connections against the host device documentation before applying power. Use proper enclosure ventilation if the host unit requires it, and follow local regulations for radio equipment installation and wiring.
