Ajax FireProtect Jeweller Smoke Detector w/ Sounder - Wireless Addressable EN54

The Ajax FireProtect Jeweller EN54 Wireless Addressable Smoke Detector with Sounder integrates optical smoke detection and an audible alarm output into a single wireless unit, offering a compact and efficient approach to professional fire alarm system design.

As part of the Ajax EN54 wireless fire alarm range, the device is well-suited to commercial buildings, refurbishment projects, and installations where laying dedicated fire alarm cabling would be disruptive or cost-prohibitive. Combining detection and sounder functionality within one housing reduces the total number of components needed on site, supporting tidier system layouts and quicker commissioning.

Smoke detection is handled by an optical sensor housed within a patented chamber engineered to resist dust ingress and insect interference, helping to sustain reliable long-term performance with reduced maintenance demands. A dual-spectrum sensor using both blue and infrared LEDs works in conjunction with the HazeFlow 2 algorithm to assess smoke characteristics and differentiate genuine smoke from steam or vapour, lowering the likelihood of unwanted alarm activations.

The built-in sounder delivers a local audible warning directly from the detector itself, extending alarm coverage within the protected space without the need for a separately installed sounder device. Wireless connectivity is provided through Ajax Jeweller radio technology, giving stable, long-range communication with compatible Ajax fire alarm control equipment.

All configuration and ongoing device management take place within the broader Ajax ecosystem, allowing installers to handle commissioning, routine maintenance, and system adjustments through a consistent and familiar set of tools.
