## Summary description

Ajax Heat Detector FireProtect EN54 is a wireless, addressable heat detector with an integrated sounder in a black housing. Compliant with EN54, it detects thermal events and provides local audible alerting. Designed for installation in buildings to monitor for fires where smoke detection is unsuitable, it offers quick heat-based alarm signaling and integration with Ajax security systems.

## Long description

Ajax Heat Detector FireProtect EN54 wireless addressable sounder in black is a compact heat detector with an integrated audible alerter designed for environments where smoke detectors are impractical. Compliant with EN54 standards, the device monitors temperature changes and triggers a local sounder to notify occupants of a thermal event. It is intended for use as part of an Ajax security and fire-detection ecosystem, enabling wireless communication with a central hub and allowing addressable placement within a monitored zone.
Advantages
The detector combines heat sensing and a built-in sounder in a single unit, reducing the need for separate alarm devices. Wireless connectivity permits flexible placement without additional cabling, while addressable operation supports precise localization within a monitored area. EN54 compliance ensures the sensor meets recognized European performance and safety requirements for fire detection devices. The black housing provides a discreet appearance suitable for commercial and residential interiors where visual integration is important.
Suitable for
 Rooms with high dust, steam or fumes where smoke detectors produce false alarms
 Kitchens, boiler rooms and garages where heat rise is a primary indicator of fire
 Commercial premises requiring EN54-certified heat detection
 Integration into Ajax wireless security and fire systems for zoned monitoring
Key specifications
 Detection type: fixed temperature and rate-of-rise heat sensing
 Integrated audible alerter: built-in sounder for local alarm signaling
 Mounting: ceiling or wall mount in a compact surface enclosure
 Housing color: black for low-visibility installation
 Standards compliance: manufactured to meet EN54 requirements for fire detection
 Compatibility: works with Ajax hubs and addressable wireless system architecture
How to use
Install the unit on a ceiling or wall following the spacing guidelines appropriate for heat detectors and the installation recommendations of the building code. Pair the detector with an Ajax hub or compatible control unit using the system’s addressable device enrollment procedure. After mounting and pairing, verify detector operation by running a built-in test or using the hub’s test function to confirm wireless connectivity and local sounder operation. Position the detector so it monitors the intended zone and avoid placing it too close to direct heat sources that may cause nuisance alarms.
Usage recommendations
Regularly test the detector through the Ajax system and inspect mounting locations for obstructions. Maintain the device according to manufacturer guidelines, replacing batteries or components as specified. Use heat detection in areas where smoke detection is unreliable, and coordinate placement with other detectors in the system to ensure full coverage and minimize false alarms.
