Overview
The Ajax EN54 Fire ReX Jeweller is a wireless range extender that increases the coverage of Ajax fire systems. It receives signals from detectors and control panels, then forwards them to extend communication across larger buildings. It keeps the system stable by monitoring signal quality and switching channels when interference appears.
Large Area Coverage
ReX EN54 offers up to 1,800 metres of open air coverage. You can add multiple extenders to widen the protected area. A network of extenders can increase system coverage to as much as 35km², which supports projects with large or complex layouts.
Sleek Design
The AJAX EN54 Fire ReX Jeweller has a compact enclosure with a clean, modern finish. It is available in black or white, which helps it blend with different interior styles. The design supports discreet installation in commercial and residential settings.
Remote Configuration
The AJAX EN54 Fire ReX Jeweller can be monitored and configured through the Ajax apps. Installers can adjust settings, view status information and run tests without visiting the device. This remote functionality supports quicker setup and easier maintenance.
Battery Capacity
ReX EN54 includes built-in backup batteries that keep it running if the main power supply fails. This helps maintain communication across the system during outages.
Installation recommendations
ReX EN54 is for indoor use. You should use a GlandBox when power and signal cables do not run inside the wall, which gives the device suitable protection and strain relief.
Approvals
ReX EN54 meets relevant EN54 fire detection and alarm standards. These approvals confirm its performance for fire system communication and its suitability for fire protection projects in regulated environments.
