Strengthen audible fire notification in commercial and public spaces with the Ajax EN54 FireProtect (Sounder) Jeweller — a standalone wireless addressable fire alarm sounder optimized for EN 54 compliance. Certified to EN 54-3 (fire alarm sounders), EN 54-25 (wireless components), and BOSEC approved, this device meets stringent European requirements for offices, retail environments, hospitality, educational institutions, municipal buildings, and other high-occupancy areas.
With a powerful 100 dB buzzer (at 1 m / 3.3 ft, adjustable via Ajax apps), it offers 32 selectable tone patterns compliant with EN 54-3 temporal standards. In a fire alarm event (triggered by EN54 detectors, manual call points, or system signals), the sounder activates in under 3 seconds and synchronizes automatically with all connected sounders for unified, high-impact evacuation alerts that overcome background noise.
Installation is effortless and wiring-free: mount on walls or ceilings using the SmartBracket (with adjustable positioning for optimal coverage), scan the QR code in the Ajax app, and configure zones, tones, volumes, and scenarios quickly. Jeweller radio protocol ensures encrypted two-way communication, frequency hopping, anti-jamming, device authentication, and up to 5,550 ft (1,700 m) range in open space (with CIE or range extender).
Battery-powered with 4 × CR123A (pre-installed, up to 5 years life), it provides advance low-battery notifications and supports tool-free replacement without disassembling the enclosure. Key protections include tamper alerts on removal/sabotage, continuous self-diagnostics, fault reporting, and full integration into the Ajax EN54 ecosystem for unified control of fire detection, audible alarms, intrusion, video, and automation via Ajax apps.
Available in sleek White (WH), Black (BL), and Red (RED) variants to blend with or stand out in any interior design while maintaining IP21C (or higher in series) protection, durable UL 94 V-0 enclosure, and operation from 32°F to 122°F for reliable indoor 24/7 use. Choose Ajax EN54 FireProtect (Sounder) Jeweller in WH/BL/RED for loud, synchronized, compliant audible alerts, fast setup, and enhanced fire safety in professional commercial settings.
