Abstract
A smoke detection device comprises a housing, a control unit with a power unit, and a scattered light sensor. The sensor comprises an optical chamber having a first emitter, a second emitter, and a photoreceiver therein. The optical chamber is within a filtration chamber having output openings that are coupled to the optical chamber via a labyrinth that terminates as a ring slit between the optical chamber and the filtration chamber. The control unit constantly provides power impulses to the first emitter, and connects the second emitter to the power unit at a moment when a threshold signal arises at the photoreceiver, determines signal levels of the photoreceiver that arise during providing of the power impulses to the first and the second emitters, and initiates an alarm if the level within the second emitter connection period is at least 20% greater than the level within the first emitter connection period.
