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

A wireless addressable point heat detector with a built-in fire alarm sounder, developed for professional fire detection installations where reliable heat detection and local audible alarm output are both required from a single device.

By combining detection and notification in one unit, the device helps streamline wireless fire alarm installations by removing the need for dedicated sounder devices in every location, making it a practical choice where faster deployment, minimal cabling disruption and a cleaner system layout are priorities. Well-suited to commercial premises, retrofit projects and buildings where conventional wired infrastructure is not feasible, it offers a flexible approach to contemporary fire detection.

Heat detection is achieved through dual thermistors, enabling an accurate response to flaming fires and rapidly rising temperature conditions. A range of detection modes is supported, including A1, A1R, A1S, B, BR, BS, C, CR, CS and fixed temperature, allowing configuration to be tailored to specific application needs.

As part of the Ajax EN54 wireless fire alarm range, the device communicates via Ajax Jeweller wireless technology, providing stable long-range connectivity and straightforward system integration. Installation and setup are handled entirely within the Ajax ecosystem, helping to reduce commissioning time compared with more traditional wired approaches.

The onboard sounder delivers local alarm notification directly from the detector, supporting occupant awareness and effective alarm signalling throughout the protected area.
