Ajax FireProtect Jeweller EN54 Wireless Addressable Heat Detector w/ Sounder

The Ajax EN54 FireProtect (Heat/Sounder) Jeweller is a wireless addressable point heat detector with an integrated fire alarm sounder, designed for professional fire detection applications where dependable heat detection and local audible alarm indication are required.

Combining detection and notification within a single device, this unit helps simplify wireless fire alarm installations by reducing the need for separate sounder devices, making it particularly useful where faster installation, reduced cabling disruption and cleaner system design are priorities. Suitable for commercial premises, retrofit projects and buildings where wired infrastructure may be impractical, it provides a flexible approach to modern fire detection.

The detector uses two thermistors for accurate heat detection, supporting reliable response to flaming fires and rapid temperature rise conditions. Multiple heat detection modes are supported, including A1, A1R, A1S, B, BR, BS, C, CR, CS and fixed temperature operation, allowing system configuration to suit application requirements.

Built as part of the Ajax EN54 wireless fire alarm range, the detector communicates via Ajax’s Jeweller wireless technology for stable long-range connectivity and streamlined system integration. Installation and configuration are completed through the Ajax ecosystem, helping reduce commissioning time compared with more traditional wired alternatives.

The integrated sounder provides local alarm notification directly from the device, helping improve occupant awareness and supporting effective alarm signalling within the protected area.
