Product description (Unique text)

The AJ-EN54-FP-H-SND/B combines reliable heat detection with direct acoustic alarm in one compact unit. Thanks to support for multiple EN54-5 detection classes (A1, A1R, A1S, B, BR, BS, C, CR, CS, and fixed temperature), this detector is suitable for a wide range of project environments, such as kitchens, technical rooms, warehouses, and utility buildings.

The integrated siren (85 dB at 1 meter) complies with EN54-3 and enables local alarms without additional signal generators. Communication takes place via the encrypted Jeweller protocol (868 MHz) with a range of up to approximately 1,700 meters in open field. Continuous supervision and tamper monitoring ensure system integrity.

The black version is particularly suitable for modern interiors, hospitality applications, or visible installations where aesthetics play a role without compromising standards or performance.
