FIELD: physics, alarms.
SUBSTANCE: invention is related to computer engineering, namely to devices that perform function of fire detection at earlier stage accompanied by smoke appearance in closed premises of offices, stores, banks, warehouses, residential buildings, enterprises and institutions. In order to achieve technical result, control target is arranged on the basis of analog-digital converter that converts analog signal passing through amplifier from photodetector into digital one, and algorithmic unit controlled by units of power supply control and power reset. Device is equipped with test unit and "test" button. Algorithmic unit analyses digital signal coming from analog-digital converter and controls signal indicator and unit of alarm signal generation, and also infrared radiator is with the help of control circuit of infrared radiator.
EFFECT: reduced time of fire detection and increases sensitivity of actuation threshold correction.
