Photoelectric smoke detection

Meggitt's photoelectric smoke detector reacts to the visible, mainly light-colored smoke which generally occurs in the early stages of slow, smoldering fires, making it suitable for the surveillance of premises with high electrical risks.

The detector works on the light-scattering principle, whereby a photocell is positioned in relation to a labyrinth chamber so that only light scattered by smoke particles can influence the evaluating electronics of the detector. When the concentration of smoke increases beyond a particular threshold, the detector shall signal alarm.
