Do you know how a smoke optical alarm works?

smoke optical alarm realize fire prevention by monitoring the concentration of smoke. Our smoke detectors use photoelectric (optical)smoke sensors. Photoelectric smoke sensors are advanced technology, stable and reliable sensors and are widely used in various Fire alarm system

The smoke moved up and reached the ceiling. Smoke optical alarm detect fires through smoke. When you don't see the flame or smell the smoke, the smoke detector already knows. It works non-stop, 24 hours a day, 365 days a year. At the time of the alarm, it made a squealing noise until the smoke dispersed. In a real fire it worked until it was burned.

The photoelectric sensor measures the concentration of smoke through a beam of light and a light sensor. When the device was designed, the beam was deviated from the sensor. When the smoke enters the induction chamber, the smoke particles will scatter part of the light beam onto the sensor. As the concentration of smoke gradually increases, more light beams will be scattered on the sensor. When the beam reaching the sensor reaches a certain level, the buzzer will sound. so that means the smoke optical alarm started working...
