Low-profile photo-optical smoke detector, complete with teach-in circuit and short-circuit isolator

Smoke detectors work according to the light scattering principle caused by smoke particles present in the air. The smoke detector features an automatic ga in control function; a microcontroller calculates reading compensation to keep constant sensitivity and corrects any level increase due to dust depositing into the analysis cell. Smoke detectors should be installed in places protected against draughts which may divert the flow o f combustion particles and in places where the common activities performed do not cause the combustion of gases.
