The smoke detector produced by our company (Product Model: XKCON-GQQ5) is developed based on optical scattering technology and is classified as intrinsically safe detection equipment for mining use. 

Operating Principle:
When smoke particles in the air enter the detection chamber, they scatter infrared light of a specific wavelength. The built-in photoelectric components in the sensor capture changes in the intensity of the scattered light, convert it into electrical signals, and transmit them to the control system.

Industry Applications:
1. Can be connected to power-off devices and audible-visual alarm devices to achieve alarm and power-off control.
2. Can be installed in underground coal mine belt conveyor tunnels, electromechanical rooms, goaf areas, and working faces.
3. Complies with explosion-proof requirements for mines and other flammable and explosive environments, and can be linked with belt comprehensive protection devices and other systems to form a multi-level safety protection network.
4. Can be used in conjunction with various production and safety monitoring systems.

It is used to monitor fire incidents in underground coal mines caused by mechanical friction, cable overheating, spontaneous combustion of coal seams, and other reasons.
