Smoke and Heat Detector
Model: HM-612PC-4
This product named Photoelectric smoke and heat detector(hereinafter called detector) detects the smoke by a couple ofinfrared diodes, includes a built-in +57 °C heat detector. The principle of detecting 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'taffect the smoke into it. While there is no smoke, the diode can receive very weak infrared light. W hen the smoke entering thechamber, diode can receive more and more light, and the detector can give out alarm signal when the smoke attains thecertain density. In order to reduce the interference and lower power consumption, the emitting circuit adopts thepulse signal. The product in accordance with the networking approach is divided into 2- wire and 4-wire detectors.
