Ajax EN54 FireProtect (Smoke/Sounder) Jeweller – Wireless Smoke Detector with Built-in Sounder
The Ajax EN54 FireProtect (Smoke/Sounder) Jeweller is an all-in-one wireless addressable smoke detector and fire alarm sounder. Certified to EN 54-3, EN 54-12, and EN 54-25 standards, it combines Ajax's patented smoke chamber technology with a powerful integrated sounder, delivering both early fire detection and immediate audible alerting from a single device.
Advanced Smoke Detection + Powerful Sounder
The patented smoke chamber with dual-spectrum optical sensor (blue and infrared LEDs) accurately identifies smoke particles while the HazeFlow 2 algorithm filters out false triggers from dust, steam, and vapour. When a genuine fire is detected, the built-in sounder activates at up to 95 dB following an EN 54-3 compliant temporal pattern. Sounders across the entire system synchronise automatically for simultaneous, unmistakable alerting throughout the building.
Cost-Effective Two-in-One Solution
By integrating detection and alerting in one device, the Smoke/Sounder variant reduces installation time, device count, and overall system cost compared to separate detector and sounder installations. This makes it particularly attractive for projects where budget efficiency matters without compromising on safety standards compliance.
Reliable & Secure
Jeweller encrypted radio protocol provides up to 1,700 m range with two-way confirmed communication. The detector operates 24/7 and features dual tamper protection. Pre-installed CR123A batteries deliver up to 5 years of operation with advance low-battery alerts via Ajax apps.
