Model Number: HM-612DC-4 1602250 Brand Name: HEIMAN Key Specifications/Special Features: 4-wire photoelectric smoke & heat detector (network)IntroductionThis product named photoelectric smoke and heat detector (hereinafter called detector) detects the smoke by a couple of infrared diodes, includes a built-in 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'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 product in accordance with the networking approach is divided into 2- wire and 4-wire detectors.
