Product Introduction:
<br />
<br />    This small gadgets will alert and warn people stay far away from danger field when it detected smoke.
<br />
<br />    This product named Photoelectric detector (hereinafter called detector) detects the smoke by a couple of infrared diodes.
<br />
<br />    The principle of detecting is granule in the smoke can reflect infrared light. Infrared diodes are placed in the special chamber.
<br />
<br />    The chamber can shield external light, but does not affect its smoke. Although there is no smoke, but the diode can receive very weak infrared light.
<br />
<br />    When the smoke enters the chamber, the diode can receive more and more light, when the smoke reaches a certain density, the detector can send an alarm signal.
<br />
<br />    In order to reduce the interference and reduce the power consumption, the sending circuit adopts the pulse signal.
<br />
<br />    Detector using a special structural design and application-specific integrated circuits, with dust, moth, anti-interference characteristics of the light source.
<br />
<br />    The detector is suitable for detecting smoke in rooms, shops, hotels, restaurants, office buildings, schools, banks, libraries, computer rooms and warehouses.
