EN54 FireProtect (Smoke/Sounder) Jeweller in Black is a wireless fire detection device designed for professional fire alarm installations where both rapid detection and local audible warning are required. Combining smoke detection, temperature monitoring, and an integrated alarm sounder in a single addressable device, it helps simplify system design while maintaining compliance with EN54 standards.

Built around Ajax's advanced fire detection technology, the detector uses a dual-spectrum optical sensor to identify smoke particles while reducing the likelihood of false alarms. Two precision thermistors continuously monitor temperature changes, enabling the device to react to developing fire conditions even when visible smoke is minimal.

The black finish makes this model particularly suitable for modern commercial interiors, hospitality environments, architectural projects, and design-conscious spaces where standard white detectors may be visually intrusive. The discreet appearance allows the device to blend more naturally into darker ceilings and contemporary décor schemes.

As part of the Ajax wireless fire system, the detector communicates using secure Jeweller radio technology, eliminating the need for extensive cabling and enabling faster installation in both new-build and retrofit projects. Long battery life helps minimise maintenance requirements, while remote configuration and diagnostics through Ajax software provide installers with a streamlined commissioning and servicing experience.

Regular system health monitoring, automated notifications, and detailed maintenance reporting help ensure ongoing reliability throughout the life of the installation. Whether used as a standalone fire detection point or as part of a larger Ajax fire safety network, the EN54 FireProtect (Smoke/Sounder) Jeweller Black delivers dependable performance, straightforward deployment, and an aesthetically refined finish.

Offered in both black and white. Find the white version here.
