It can detect a large amount of smoke generated during a fire and send out an alarm signal in time. The detector is controlled by MCU, which can intelligently judge the smoke generated during a fire and give an alarm. The alarm adopts photo-inductive smoke devices and excellent production technology. It is stable in work, beautiful in appearance, simple to install, and requires no debugging. It can be widely used in hotels, stores, Internet cafes, song and dance halls, cafes, leisure halls, residential and other places for fire safety monitor. The alarm has a built-in buzzer and emits a strong sound after the alarm. The alarm is powered by a 9V laminated battery, which consumes little electrodes, and can last for more than one year.
The working principle of the smoke detector:
The infrared beam of the infrared emission tube is scattered by the soot particles, and the intensity of the scattered light is proportional to the smoke concentration. Therefore, the intensity of the infrared beam received by the photosensitive tube will change, converted into a point signal, and finally into an alarm signal.
Smoke detector: It is a collective name for smoke fire alarm. There are two types of smoke detectors, ionic smoke detectors and photoelectric smoke detectors. There are mainly three types of smoke detectors in terms of use: independent, networked, and wireless.
