Shenzhen Heiman Technology Co. Limited

Model Number: HM-612DC-4 G17051036 Brand Name: HEIMAN Key Specifications/Special Features: 4-wire photoelectric smoke and heat detector (network)Introduction:This product named photoelectric smoke and heat detector (hereinafter called detector) detects the smoke by couple of infrared diodes, includes built-in heat detectorPrinciple of detecting is granule in the smoke can reflect infrared lightInfrared diodes are placed in the special chamberChamber can shield external light, but doesn't affect the smoke into itWhile 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
Product in accordance with the networking approach is divided into 2- wire and 4-wire detectors
