Scale your EN54-compliant fire safety system effortlessly with the Ajax EN54 Fire ReX Jeweller — the wireless addressable range extender built for large-scale commercial, municipal, and complex sites. Part of the innovative EN54 Line, it significantly extends the radio network of the EN54 Fire Hub Jeweller, delivering stable connections through challenging obstacles like steel, concrete, or multi-level structures.

With a wireless range of up to 1,800 meters in open space and support for up to 5 extenders per system (covering up to 35 km²), it enables flexible device placement for fire detectors, sounders, manual call points, intrusion sensors, and automation modules — all within the CIE's device limits. Dual connectivity (Jeweller/Wings/TurboWings radio + Ethernet as primary wired channel) guarantees unbreakable links, with alarms reaching the CIE in just 3 seconds (exceeding EN 54-21 requirements) and full event confirmation.

Advanced security features include block encryption with dynamic keys, frequency hopping for jamming resistance, tamper alarms (two buttons for detachment/enclosure opening detection), and instant notifications. It supports photo/video alarm verification to minimize false calls and integrates seamlessly with Ajax apps for remote configuration, monitoring, and over-the-air updates — no on-site visits needed for new features.

Installation is professional yet simple: mount using the included SmartBracket (no disassembly required), connect mains power (110–240 V~), add optional EN54 Internal Battery (24h or 72h, sold separately) for blackout resilience, scan the QR code in Ajax PRO apps, and test coverage instantly. Hot-swappable batteries keep the system online during maintenance. Available in sleek white and black finishes, the EN54 Fire ReX Jeweller combines EN 54 fire compliance (EN 54-4, -18, -25) with EN 50131 Grade 2 intrusion protection — redefining reliable, future-proof fire and life safety for warehouses, offices, schools, historic buildings, and beyond.
