IPC: G08B17/10
Filed: 1980-07-14
Abstract: PURPOSE:To remove noise owing to scattered light and eliminate the possibility for failure in announcement by utilizing the difference in arrival times at a photodetector based on the optical path difference between the measuring light arriving at the same by reflecting on a retroreflective plate and the scattered light by smoke. CONSTITUTION:Pulselike measuring light is emitted from a light emitting device 1 by the periodic pulses of a pulse oscillator 4. This measuring light reflects on a retroreflective plate D, and is detected after a constant time t0. Here, the delay time of a delay circuit C connected to the oscillator 4 is set at t0, and a switch 6 is closed after the t0 time since the generation of the pulses.
