Product Introduction
(SMOKE DETECTOR)

This small gadget will alert and warn people stay far away from danger field when it detects smoke.

How this device works

This product named Photoelectric detector (hereinafter called detector) detects the smoke by a couple of infrared diodes.

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 don't affect the smoke into it.

While have no smoke, the diode can receive very weak infrared light. When the smoke entering the chamber, diode can receive more and more light, when the smoke attains the certain density, the detector can give out alarm signal. In order to reduce the interference and lower power consumption, the emitting circuit adopts the pulse signal.

The detector adopts the special structure design and ASIC, has the dustproof, mothproof and anti outside light interference feature etc.

The detector is suitable for detect the smoke at house, in shops, hotel, restaurant, office building, school, bank, library, computer house and storerooms etc.

 TEST THE DEVICE ATLEAST ONCE A MONTH

Please clean the detector by soft brush regularly

Install battery correctly

When the voltage is low or chamber is dirty, the detector will beep once per 40 seconds.
(In this condition, clean the air vents of the smoke detector to make sure it's dust free. If the detector still beeps after you have clean it up, the next step is to replace the 9V battery)
