EN54 FireProtect (Smoke/Sounder) Jeweller – Smoke detector with integrated alarm siren

The EN54 FireProtect (Smoke/Sounder) Jeweller combines precise smoke detection with an integrated audible alarm in a single EN54-certified device. It is particularly suitable for areas where a local, immediately audible warning is required.

The patented smoke chamber with dual-spectrum sensor detects smoke early and minimizes false alarms. Additionally, the detector features an 85 dB siren with selectable alarm tones, providing immediate warning to people inside the building – independent of mobile devices or control centers.

Wireless communication ensures a stable connection to the CIE over long distances. Setup is tool-free via the SmartBracket mounting plate, and maintenance and status monitoring are fully remote. The long battery life of up to five years significantly reduces maintenance requirements.

communication

• Jeweller Communication Technology

Proprietary radio technology for transmitting commands, alarms, and events.

• • Radio frequency bands: 866.0-866.5 MHz 868.0-868.6 MHz 868.7-869.2 MHz 905.0-926.5 MHz 915.85-926.5 MHz 921.0-922.0 MHz
  • Maximum effective radiated power (ERP): up to 20 mW
  • Radio signal modulation: GFSK
  • Radio range: up to 1700 m

Between the device and a control and display unit (CIE) or a radio signal amplifier in free space.

Smoke detection

• Sensor element: optical dual-spectrum sensor

Detects smoke based on particle size in the air.

• Protection against false alarms: The device does not react to water vapor.
• Patented smoke chamber: Protects the smoke sensor from dust, dirt and insects.

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.

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.
