The principle of how the detector works is that a granules in the smoke reflect infrared light. Infrared diodes are located in a special chamber in the detector. The chamber can shield external light, but is not affected by smoke entering it. But when the smoke enters the chamber, the diodes receive more and more light.
When the smoke accumulates to a certain density, the detector will give the alarm signal. To reduce interference and lower energy consumption, the circuit adopts the heart rate signal.
With the special structured design, the detector also adopts the Application Specific Integrated Circuit (ASIC) and it has a dust-protected, moth-proof and anti-outside light interference function, etc.
The detector is suitable for office buildings, schools, banks, libraries and warehouses, etc.
