SMOKE DETECTING FIRE WARNING SENSOR |
摘要 |
The smoke detector has a fixing socket in which a detector insert with an optical module is fitted. The optical module has a light source (6) and a photodetector (7) contained within a measuring chamber having a base (11). The module further has a labyrinth system provided by plates (9) projecting inwards from the periphery of the measuring chamber. The base of the measuring chamber has a conical or pyramid shape so that its centre lies at a greater distance from the plane containing the light source and the photodetector than its periphery. |
