Smoke detectors are triggered when the smallest particles of smoke enter the optoelectronic sensor camera. The response rate of the device depends on their saturation. The principle of operation of smoke detectors is based on the fact that the sent beam is dispersed in the presence of smoke particles in the air. The device detects this change in radiation with a special sensor. The slightest “blurring” leads to the activation of the alarm system.

The smoke detector is very popular due to its high sensitivity, as well as rapid response to the outbreak of a fire. Its mechanism does not fail, and the number of false positives is minimized.

Classification of smoke detectors

In accordance with GOST, smoke detectors are divided according to the principle of operation into:

· optoelectronic;

· ionization;

· electro-induction.
