Zusammenfassung:To provide a smoke monitoring system that makes it possible to change sensitivity of a smoke sensor depending on a time even if the smoke sensor does not manage a threshold before and after the sensitivity is changed.SOLUTION: In a smoke monitoring system including: a monitor device; a smoke alarm board connected to the monitor device; and a subordinate smoke sensor connected to the smoke alarm board, the monitor device is configured to transmit a threshold different depending on a time to the smoke sensor via the smoke alarm board. The subordinate smoke sensor has: a storage unit; an acquisition unit that acquires the threshold via the smoke alarm board from the monitor device via the smoke alarm board; a change unit that, when the threshold is newly acquired by the acquisition unit, changes the existing threshold stored in the storage unit to the newly acquired threshold; a measurement unit that measures the density of a smoke; and a transmission unit that transmits a detection result of the smoke indicative of a result of comparing the smoke density with the post-changed threshold stored in the storage unit to the smoke alarm board. The smoke alarm board is configured to output an alarm in accordance with the detection result of the smoke received from the smoke sensor.SELECTED DRAWING: Figure 4 【課題】煙センサが変更前後の閾値を管理しなくても、煙センサの感度を時間によって変更できるようにした煙監視システムを提供する。【解決手段】監視装置と、監視装置に接続されている煙警報盤と、煙警報盤に接続されている従属型煙センサと、を備える煙監視システムにおいて、監視装置は、時間によって異なる閾値を煙警報盤を介して煙センサに送信する。従属型煙センサは、記憶部と、監視装置から煙警報盤を介して閾値を取得する取得部と、取得部により閾値が新たに取得されると、記憶部に記憶された既存の閾値を新たに取得された閾値に変更する変更部と、煙の濃度を測定する測定部と、煙の濃度と記憶部に記憶された変更後の閾値とを比較した結果を示す煙の検出結果を煙警報盤に送信する送信部と、を有する。煙警報盤は、煙センサから受信した煙の検出結果に応じた警報を出力する。【選択図】図4
