AJ-EN54-FP-H-SND Heat/Sounder Wit

Ajax Systems AJ-EN54-FP-H-SND – FireProtect Heat/Sounder (white)

The AJ-EN54-FP-H-SND is a professional, wireless thermal fire detector with an integrated siren, developed for EN54-certified fire alarm systems. This detector combines accurate heat detection with direct acoustic alarms, making it ideal for environments where smoke detection is less effective, such as kitchens, technical rooms, and storage locations.

Technical positioning

The detector operates in accordance with EN 54-5 (heat detection) and EN 54-3 (acoustic alarm) and communicates with the central fire hub via the secure Jeweller protocol. Thanks to dual thermistor monitoring, the system detects both rapid temperature rises and exceeding a fixed temperature threshold. This minimizes false alarms and increases reliability in professional applications.

Key features

• Detection type: Thermal detection (fixed threshold + rate-of-rise)

• Integrated siren: Powerful acoustic alarm in accordance with EN 54-3

• Wireless communication: Up to approximately 1,700 meters in open field

• EN54 certified: Suitable for certified fire alarm systems

• Tamper protection: Built-in tamper switch to prevent removal

• Long battery life: Multi-year autonomy with pre-installed batteries

• Quick installation: SmartBracket mounting and configuration via QR code

Area of application

The AJ-EN54-FP-H-SND is used in professional fire alarm projects where reliability, standard compliance, and ease of installation are key. The integrated siren enables local alarms without additional wired signal transmitters, reducing installation time and infrastructure costs.

This detector functions within an Ajax EN54 fire alarm system and requires a compatible fire hub for full integration, monitoring, and reporting.
