## Summary description

UART Bridge Module Ajax 000001160 provides a UART-to-RS-485 communication interface for integrating Ajax devices with RS-485 networks. Designed for signal conversion and reliable data transmission, it enables connection of compatible controllers and peripherals over differential RS-485 lines. Suitable for system integration, monitoring, and extending wired communication in security and automation setups.

## Long description

Ajax uartBridge is a module for integrating Ajax wireless detectors into third-party security and smart home systems via a UART interface. The device converts signals between the Ajax Jeweller radio network and UART, enabling connection to RS-485 controllers and other peripherals when used with appropriate converters. It supports long-range wireless communication and provides monitoring data for each connected detector.
Advantages
Jeweller radio technology provides reliable wireless links up to 2,000 meters in open space and across several floors, with support for up to 85 devices. The module employs authentication, encrypted communication and frequency hopping to protect against fraud and jamming, and it monitors detector performance, battery level and alarm states. Operation uses a UART interface at 57,600 Bd and the module receives power from the UART connection (DC 5 V), simplifying installation and integration into professional systems.
Suitable for
Integrating Ajax wireless detectors into third-party security panels and smart home controllers
Connecting Ajax networks to RS-485 systems via UART-to-RS-485 converters
Commercial and residential installations requiring remote detector placement across floors or large open areas
Key specifications

Dimensions: 64 × 55 × 13 mm (without antennas); 110 × 58 × 13 mm (with antennas)
How to use
Connect the uartBridge to the host controller via the UART interface configured at 57,600 Bd and, if required, add a UART-to-RS-485 converter to link with RS-485 networks. Place the module indoors within range of the Ajax detectors and ensure it receives 5 V DC from the UART connection. Register the module in the host system according to the controller’s integration procedure so that detector statuses, alarms and battery levels are transmitted and monitored.
Usage recommendations
Install the module in a location with minimal RF obstacles and keep antennas positioned according to the manufacturer’s guidance to achieve the stated 2,000 m line-of-sight range. Use proper grounding and follow RS-485 wiring practices when converting the UART output for differential transmission. Ensure firmware updates are applied to maintain compatibility and security.
