Enhance commercial fire protection with the Ajax EN54 FireProtect (Smoke/Sounder) Jeweller — a professional wireless addressable smoke detector integrated with a powerful fire alarm sounder. Certified to EN 54-7 (point smoke detectors), EN 54-3 (fire alarm sounders), EN 54-25 (wireless components), and BOSEC approved, this device meets rigorous European requirements for commercial, retail, hospitality, educational, and municipal environments.

The core detection technology features Ajax's patented smoke chamber with a dual-spectrum optical sensor (blue and infrared LEDs) and the advanced HazeFlow 2 algorithm. This combination analyzes smoke particle size and characteristics for swift identification of smoldering or flaming fires while effectively filtering out nuisance triggers like steam, dust, or aerosols — delivering best-in-class accuracy and minimal false alarms.

Upon smoke detection, the integrated sounder activates with up to 85 dB volume (adjustable via Ajax apps), 32 selectable tone patterns, and automatic synchronization across all sounder-equipped devices in the system — ensuring clear, unified evacuation alerts in seconds through Jeweller protocol. The sounder uses temporal patterns compliant with EN 54-3 for reliable notification.

Installation is fast and minimally invasive: no cabling required. Secure to the ceiling using the SmartBracket (with 90° rotation for precise alignment), scan the QR code in the Ajax app, and configure zones, rooms, scenarios, and tests effortlessly. Jeweller radio technology provides 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 2 × CR123A (pre-installed, up to 5 years life), it includes proactive low-battery alerts and easy tool-free replacement. Additional features encompass tamper protection (alerts on removal/sabotage), continuous self-diagnostics, fault reporting, always-on monitoring, and full integration into the Ajax ecosystem for combined fire, intrusion, video, and automation management.

With IP20/IP21C protection, robust UL 94 V-0 enclosure, and operating from 32°F to 122°F, it's engineered for dependable indoor 24/7 performance. Choose Ajax EN54 FireProtect (Smoke/Sounder) Jeweller for rapid deployment, exceptional detection reliability, synchronized alerting, and certified compliance in high-demand commercial settings.
