EN54 FireProtect (Heat/Sounder) Jeweller – Heat detector with acoustic alarm

The EN54 FireProtect (Heat/Sounder) Jeweller combines reliable heat detection with an integrated audible alarm function . It is ideal for areas where both temperature-based fire detection and direct on-site warning are required.

Dual thermistor technology detects dangerous heat build-ups early, while the integrated 85 dB alarm immediately alerts people inside the building. The alarm parameters can be precisely adjusted to the specific environment to ensure maximum safety with minimal false alarms.

The detector communicates wirelessly with the fire alarm control panel via the Jeweller protocol and maintains a reliable connection even in large buildings. Its simple installation, addressable device assignment, and long battery life make it the ideal solution for professional EN54 installations.

Detection of dangerously high temperatures

• Sensor element: 2 × thermistor

In accordance with the requirements of EN 54-5 for heat detectors of classes A1, B and C with response types temperature rise (R) and static (S).

• Heat sensor modes: A1, A1R, A1S, B, BR, BS, C, CR, CS, Set temperature

For improved fire hazard detection, depending on the device's installation location. Can be selected in the device settings.

Announcement of the alarm

• Alarm type: acoustic
• Volume: up to 95 dB at a distance of 1 m

Adjustable by PRO users or users with administrator rights in an Ajax app.

• Tone pattern: 32 tones
• Sound synchronization: An acoustic alarm is automatically synchronized with all devices that have a signal transmitter and are connected to the same CIE.
• Alarm announcement test: A check of the audible alarm to ensure that the fire alarm is clearly audible in the premises.

--- Installation Recommendations ---

This device is only suitable for indoor use.

The SmartBracket mounting plate allows the detector to be rotated by up to 90° even after installation.
