HC- 407A Fixed Temperature Heat Detector Hong-Chang

HC- 407A Fixed Temperature Heat Detector ( Hong-Chang ) Characteristics 1. There are two LED which can turn 360o and watch the situation of the detector at any angle 2. Joint functioning way: NO type and NC type. 3. The use of common base is advantageous to the exchange of detector. Functioning way Outside the fixed-temperature heat detector are exposed a temperature-preset sensing head and a piece of metal that can increase the heat-receiving area. When the fire makes the room temperature rise gradually until the temperature has risen and reached the preset point of function temperature, it immediately enters the alarm status. Meanwhile, LED will be turned on automatically and give alarm to the fire signal receiving machine.
