Working Principle
The alarm utilizes a photoelectric sensor with a special structural design combined with a reliable MCU to effectively detect smoke generated during the smoldering stage of a fire in its early stages or thereafter. When smoke enters the alarm, it causes scattering from the light source, and the light receiving element detects the light intensity. The received light intensity has a certain linear relationship with the smoke concentration. The alarm continuously collects, processes, and judges on-site parameters. When it confirms that the light intensity of the on-site data reaches a predetermined threshold, the alarm's red LED lights up, and the buzzer is activated to sound the alarm. When the smoke in the environment where the alarm is operating dissipates, the alarm automatically returns to its normal working state.
