Rate of Rise Heat Detector

Characteristics:

  • Heat-sensing diaphragm can operate for unlimited number of times and is not affected by room temperature. The conducting parts use gold coating to avoid oxidation.
  • Uses glass tube to avoid humidity and stabilize the ventilation function. Glass tube also can expel non-fire heat to avoid false alarms.
  • The unit is completely sealed; its function is not affected by humidity, dust or insects.
  • This detector has passed strict quality control through automatic repetitive testing and been calibrated automatically under stable temperature and humidity conditions. This, quality and reliability are consistent from the first detector produced to millionth.
