Wireless signal transmitter Ajax 000007487 — range up to 1300 m, compatible with Ajax systems

Ajax Transmitter is a wireless module for integrating third-party wired detectors into Ajax security systems. The device connects detectors with a wired output to an Ajax Hub, enabling protection of indoor and outdoor areas. It supports one wired detector and operates as part of the Ajax ecosystem to transmit alarms and service events to the hub.

Advantages

The transmitter provides a long radio range (up to 1,600 m in open space) and works across floors and outdoors. It uses the Jeweller protocol with frequency hopping, encrypted communication and authentication to protect against tampering and replay attacks. Jamming detection and an accelerometer-triggered tamper alarm increase security. The device reports battery level and supports remote connection quality testing and interactive installation guidance for straightforward professional setup.

Suitable for

• Connecting a single wired detector (alarm input) to an Ajax Hub
• Protecting indoor and outdoor premises where wired detectors must be integrated
• Extending or relaying signal coverage across several floors or separate buildings

How to use

Install the Ajax Transmitter near the wired detector so that cable connections to the transmitter's +/- connectors are secure. Pair the transmitter with an Ajax Hub following the interactive installation manual in the Ajax mobile application. Configure the polling interval and verify connection quality remotely through the app. After installation, monitor battery level and event history from the hub or mobile app.

Usage recommendations

The transmitter works best when placed with a clear radio path to the Ajax Hub; avoid large metal obstacles and dense structures. Test the signal strength after installation and set a shorter polling interval if faster detection is required. Replace the pre-installed CR123A battery according to the device status shown in the app and follow local regulations for outdoor installation.
