EN54 FireProtect (Heat) Jeweller – Precise heat detector for demanding environments

The EN54 FireProtect (Heat) Jeweller is a wireless EN54 heat detector specifically designed for environments where smoke detectors are unsuitable, such as kitchens, technical rooms or industrial areas.

Two integrated thermistors continuously monitor temperature changes and detect both rapid temperature increases and static threshold exceedances. The detection modes A1R, A1S, BR, BS, CS, or a fixed temperature can be flexibly configured via the Ajax apps.

The secure wireless connection enables reliable alarm transmission within seconds. The detector is ready for immediate use, can be installed in minutes, and offers an autonomous operating time of up to 5 years thanks to energy-efficient technology.

Sabotage protection

• Tamper contact: Error notification if an attempt is made to remove the device from the mounting plate.
• Slot in front of SmartBracket: for attaching the device to the SmartBracket mounting plate

When locked, the lock secures the device and prevents it from being removed without special tools.

• Protection against device spoofing: Device authentication
• Detection of connection loss: after 36 seconds

The detection time depends on the jeweler's settings.
