The DHA-1L, 2L line type heat detectors is pneumatic detectors when the ambient temperature increases in the event of fire, the volume of heated air also expands. Air-filled sensing tubes transmit this pressure increase to a sensor in the tube terminal processor. The system triggers an alarm as soon as a defined limit is exceeded. DHA-1L type is highest sensitivity.<\/p>\n
