Wired Heat Alarm Detector

Description

• This product named Photoelectric heat detector (hereinafter called detector) detects the heat by a couple of infrared diodes.
• The principle of detecting is granule in the heat can reflect infrared light. Infrared diodes are placed in the special chamber.
• The chamber can shield external light, but doesn’t affect the heat into it. While there is no smoke, the diode can receive very weak infrared light. When the heat entering the chamber, diode can receive more and more light, and the detector can give out alarm signal when the heat 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.
