Product Description:
This product named Photoelectric smoke detector (hereinafter called detector) detects the smoke by a couple of infrared diodes. The principle of detecting is granules 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 enters the chamber, the diode can receive more and more light, and the detector can give out an alarm signal when the smoke attains a 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.
Features:
*LED indicator connecting is available
*Insect proof and dust-free
*Detecting Green LED flash, Led turn on when the alarm
*Compliant for any 2 wire conventional fire alarm system
This smoke detector when it is triggered sends the signal to the fire alarm system it is working with LED flashing and sends out the sound to warn the end users on time.
