The Ajax FireProtect Jeweller EN54 Wireless Addressable Smoke Detector is a professional wireless smoke detector developed for reliable fire detection in commercial environments where flexible installation and dependable system communication are essential.

As part of the Ajax EN54 wireless fire alarm range, this addressable smoke detector is ideal for offices, commercial premises, refurbishment projects and buildings where traditional fire alarm cabling may be difficult, disruptive or impractical to install. Its wireless design helps reduce installation time while maintaining seamless integration with compatible Ajax fire alarm control equipment.

The detector features advanced optical smoke detection technology, using a dual-spectrum optical sensor with blue and infrared LEDs to improve smoke analysis and detection accuracy. Ajax’s patented dustproof and insect-resistant smoke chamber helps minimise maintenance requirements and removes the need for routine chamber cleaning, supporting reliable long-term performance.

The integrated HazeFlow 2 algorithm continuously analyses data from the optical sensor and compares it against recognised smoke patterns, helping distinguish genuine smoke from steam or vapour to reduce false alarm activations.

Powered by Ajax Jeweller wireless communication technology, the detector delivers stable long-range connectivity as part of a scalable wireless fire detection system. Configuration, commissioning and ongoing device management can be carried out through the Ajax ecosystem, helping installers simplify setup, maintenance and long-term system administration.

Designed for modern professional fire alarm installations, the Ajax FireProtect Jeweller EN54 Wireless Addressable Smoke Detector offers a practical and flexible solution where reliable smoke detection, simplified installation and efficient wireless communication are key priorities.
