Ajax EN54 FireProtect (Heat/Sounder) Jeweller
Summary
The Ajax EN54 FireProtect Heat/Sounder Jeweller detector combines advanced wireless heat detection with an integrated fire alarm sounder, delivering a comprehensive fire safety solution specifically designed for challenging environments where smoke detection may not be suitable. This wireless addressable point detector meets EN54 certification standards whilst providing both heat detection and audible alarm capabilities in a single device.
Featuring dual thermistor sensors with multiple configurable detection modes including A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature options, the detector provides precise heat detection tailored to specific environmental requirements. The integrated sounder delivers up to 85dB alarm output with 32 selectable tone patterns, ensuring effective alarm notification across the protected area. This makes it ideal for kitchens, garages, boiler rooms, and dusty industrial environments where traditional smoke detectors might cause false alarms.
With up to 5 years of battery life, alarm synchronisation across all connected devices, and seamless integration with Ajax PRO Desktop, the EN54 FireProtect Heat/Sounder Jeweller detector provides long-term reliability and simplified maintenance for professional fire safety installations requiring both heat-based detection and local alarm notification.

FAQs
What makes this detector different from a standard heat detector?
The EN54 FireProtect Heat/Sounder Jeweller combines wireless addressable heat detection with an integrated 85dB sounder, eliminating the need for separate detection and alarm devices whilst maintaining full EN54 certification compliance for challenging environments.
What heat detection modes are available and how loud is the alarm?
The detector offers multiple configurable heat detection modes (A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature) selectable via the Ajax app, with an integrated sounder producing up to 85dB at 1 metre distance and 32 different tone patterns.
Where is this heat/sounder detector most suitable?
This detector is ideal for kitchens, garages, boiler rooms, dusty industrial environments, or any location where smoke detectors might cause false alarms but where both heat detection and local alarm notification are required.
Do multiple detectors sound together during an alarm?
Yes, the system features alarm synchronisation across all connected devices, ensuring coordinated alarm notification throughout the protected area when any detector is triggered by heat conditions.
How quickly does the detector respond and sound the alarm?
The detector responds rapidly to dangerous temperature conditions and transmits alarms with integrated sounder activation within 3 seconds of heat detection, ensuring immediate local and system-wide alarm notification.
What certifications does the heat/sounder detector have?
The detector is certified to EN54-5 and EN54-25 standards and complies with Directive 2014/53/EU (RED), ensuring it meets European fire safety regulations for commercial heat detection and alarm installations.
