The thermo-differential detector detects the fires that arise. It reacts to a maximum temperature and a rise in temperature. These indicators are detected reliably and reported to the alarm centre.The thermo-differential detector is mounted at the ceiling in the middle of the room. The minimum distance to the side wall is 30cm. Since the thermo-differential detectorcontrary to optical smoke detectorsdoes not detect any smoke, it is used mainly at places having a high load of dust and smoke (kitchens, smoking zones, garages). Only when the maximum temperature has exceeded 60 °C, or the temperature rises by more than 5 °C within 3 minutes, the detector triggers an alarm. By adjusting a jumper you can configure it as NO or as NC detector. As such, it fits with every wired alarm system. The thermo-differential detector is externally supplied power with 12V operating voltage and is EN54 certified.
