The product is a photoelectric smoke detector, which works according to the principle of sensing smoke particles. With unique structural design and light processing technology, it has the functions of dust-proof, insect-proof, anti-external light interference, etc., which ensures the stability of the product from the design. This product has a good response to visible smoke caused by slow smoldering or open combustion. It is suitable for indoor environment smoke monitoring such as residence, shopping mall, hotel and warehouse. This product is a non-coded smoke detector, with a pair of switching output contacts, you can choose to normally open or normally closed output according to actual needs. When working normally, the indicator flashes once every 9 seconds; When alarm, the indicator light is on, and the alarm output contact action makes the intelligent window open automatically. 1.
