Visual-Sound Fire Detector Ajax EN54 FireProtect VAD Sounder black, Jeweller, EN54, wireless, black

Upon receiving a fire alarm signal, the device activates an audible alert of up to 100 dB at 1 meter, using a temporal sound pattern that complies with EN 54-3. Simultaneously, the red LED frame flashes at a frequency of 0.5 Hz, fully compliant with EN 54-23. Both sound and visual signals are triggered within 3 seconds after receiving the alarm command from the system.

Communication with the central unit is ensured via the secure Jeweller radio protocol (868 MHz), providing stable two-way communication at distances of up to 1700 meters in open space. The device constantly monitors its status, transmitting events such as low battery, tamper activation, connection loss, or malfunctions to the control panel or monitoring station with precise zone and device identification.

The device is powered by pre-installed CR123A batteries (main) and a CR2032 (backup for tamper protection), providing up to 5 years of autonomous operation with a 36-second polling interval.

Installation is simplified through the SmartBracket mount, allowing setup without disassembling the device. Adding it to the system is quick via QR code and mobile application. LED indicators (green, yellow, red) on the device body provide instant visual feedback on its status.
