Zusammenfassung: | To provide a smoke detector capable of suppressing generation of a non-fire report and a fire receiver.SOLUTION: A smoke detector 1 includes: light emitting elements 11, 12 for emitting light toward a smoke detection space; a light receiving element 13 for receiving scattered light when light emitted from the light emitting elements 11, 12 is scattered by a substance flowed into the smoke detection space to output an output signal for determining fire; and a signal processing unit 22 for delaying the output signal S1 output from the light receiving element 13 for a prescribed delay time. The smoke detector further includes a smoke determination unit 21 for determining whether the substance is smoke or not based on the output signal output from the light emitting element.SELECTED DRAWING: Figure 2
【課題】非火災報の発生を抑制することができる煙感知器及び火災受信機を提供する。【解決手段】煙感知器1は、検煙空間に向けて光を発光する発光素子11、12と、発光素子11、12から発光した光が検煙空間に流入した物質により散乱したときの散乱光を受光して、火災の判定を行うための出力信号を出力する受光素子13と、受光素子13から出力される出力信号S1を所定の遅延時間だけ遅延させる信号処理部22とを備える。煙感知器は、受光素子から出力された出力信号に基づいて、物質が煙か否かを判定する煙判別部21をさらに有する。【選択図】図2 |
