This product detects smoke with a pair of infrared diodes. The detector is suitable for office buildings, schools, banks, libraries and warehouses etc.

The principle of how the detector works is that a granule in the smoke reflects infrared light. Infrared diodes are placed in a special chamber in the detector. The chamber can shield external light, but is not affected by smoke entering it. When there is no smoke, the diodes receive very weak infrared light. But as the smoke enters the chamber, the diodes receive more and more light.

When the smoke accumulates to a certain density, the detector will emit an alarm signal. To reduce interference and provide lower power consumption, the circuit adopts the pulse signal.

With the special structured design, the detector also adopts ASIC (Application Specific Integrated Circuit) and it has a dust-proof, moth-proof and anti-outside light interference function, etc.

The detector is suitable for office buildings, schools, banks, libraries and warehouses etc.
