Abstract

Operation method for an optical smoke detector, in which in order to detect smoke at least one light- sensitive receiver measures the useful scattered radiation which proceeds from an element in space, which is situated in the region of intersection of the directed field of view of the light-sensitive receiver and the directed beam of a light source, in order to detect the extraneous scattered radiation generated by contamination of the measurement chamber the light- sensitive receiver or a second light-sensitive receiver detecting the radiation which proceeds from a surface element of the measurement chamber, characterised in that the reflection radiation of an illuminated surface element is measured. <IMAGE>
