In order to ensure stability, this product, which is a photoelectric smoke and temperature integrated detector (henceforth referred to as the detector), has a unique structure design and uses MCU intelligent processing of optical signal. It also has anti-light interference, dust-proof, insect-resistant, and other features. This product reacts well to visible smoke from open combustion or slow smoldering. This product has a temperature sensor and a photoelectric smoke sensor. The detector will sound an alarm when the ambient temperature rises above 57°C or the ambient smoke concentration reaches the alarm level. The device can be used to detect smoke in a variety of settings, including homes, factories, hotels, offices, classrooms, banks, libraries, and warehouses.
