Elevate commercial fire safety with the Ajax EN54 FireProtect (Smoke) Jeweller — a professional-grade wireless addressable smoke detector engineered for precision and compliance. Fully certified to EN 54-7 (smoke detectors), EN 54-25 (wireless components), and BOSEC approved, this device delivers unmatched reliability for offices, retail spaces, hotels, schools, and municipal buildings where EN 54-compliant systems are mandatory.

At its core is Ajax's patented smoke chamber paired with a dual-spectrum optical sensor (blue and infrared LEDs) and the proprietary HazeFlow 2 algorithm. This advanced technology analyzes smoke particles across different wavelengths to distinguish real fire smoke from nuisance sources like steam, dust, or cooking vapors — minimizing false alarms while ensuring rapid detection of smoldering and flaming fires. The detector remains always active, continuously monitoring for smoke presence.

Installation is effortless and non-disruptive: no wiring needed. Mount using the included SmartBracket (with 90° rotation for optimal positioning), scan the QR code via the Ajax app, and configure zones, rooms, and scenarios in minutes. It communicates securely over Jeweller radio protocol — encrypted, two-way, with frequency hopping, anti-jamming, and up to 5,550 ft (1,700 m) range in open space. Tamper protection alerts on unauthorized removal, and built-in self-diagnostics report faults instantly.

Powered by 2 × CR123A batteries (pre-installed, up to 5 years life), it provides early low-battery warnings and supports tool-free replacement. With IP21C rating, durable UL 94 V-0 enclosure, and operating range from 32°F to 122°F, it's designed for consistent indoor performance. Fully integrates into the Ajax ecosystem for unified control of fire, security, video, and automation — all manageable remotely via Ajax apps.

Opt for Ajax EN54 FireProtect (Smoke) Jeweller for swift deployment, superior detection accuracy, reduced false alarms, and certified peace of mind in demanding commercial environments.
