Photoelectric GL61-PHS INTELLIGENT ADDRESSABLE SMOKE CUM HEAT DETECTOR (MOQ3nos)

GL61-PHS is addressable photoelectric smoke and heat combination detector (hereinafter called detector) detects the smoke and heat. The principle of detecting smoke is granule in the smoke can reflect infrared light, Infrared diodes are placed in the special chamber. The chamber can shield external light, but doesn’t affect the smoke into it. While there is no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light. and the detector can give out alarm signal when the smoke attains the certain density. In order to reduce the interference and lower power consumption. The emitting circuit adopts the pulse signal. The principle or detecting heat Is the Impedance of thermistor can change following the temperature. The thermistor reads the temperature from the air it takes in and transmits signal to the control IC. If the temperature reaches or exceeds the point. the detector is triggered. This detector Is used together with the Addressable Fire Alarm Control Panel produced by our company. It employs the electroencoding method. The encoding method can refer to the Instruction of address encoder.
