Scattered light detector for detection of smoke, particularly for fire recognition, has detector and radiation source and control and evaluation electronic unit, where scattering range, particularly stray line lies outside scattered light

摘要

The scattered light detector (1) has a detector and a radiation source and a control and evaluation electronic unit (4), where a scattering range, particularly a stray line (8) lies outside of the scattered light smoke detector. The detector has a tube (10) and a scattering angle smaller ten degrees between transmission radiation (6) and a detector radiation (9).
