Smoke detectors work according to the light scattering principle caused by smoke particles
present in the air. The smoke detector features an automatic gain 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.
