Zusammenfassung: | To provide a smoke alarm board for informing an alarm-transfer destination, when a concentration of smoke measured by a smoke sensor reaches an alarm level desired by a user, to that effect.SOLUTION: A smoke monitoring system is arranged in a fire prevention object such as a server room, a data center, or a clean room. In the system, a smoke alarm board 200 to which a plurality of subordinate smoke sensors are connected via signal lines includes: an acquisition section for acquiring an alarm level corresponding to a concentration of smoke measured by the smoke sensor among the plurality of alarm levels; an alarm-transfer circuit having contact points to be connected to alarm-transfer destinations; an assignment section for assigning to the contact points the alarm levels selected by a user among the alarm levels; and an alarm-transfer control section for controlling the alarm-transfer circuit to output a signal to the alarm-transfer destination by switching the connection state of the contact point when the acquisition section acquires the alarm level assigned to the contact point.SELECTED DRAWING: Figure 3
【課題】煙センサにより測定された煙の濃度がユーザの所望の警報レベルに達したことを契機に、移報先にこの情報を伝達する煙警報盤を提供する。【解決手段】サーバー室、データセンター、クリーンルーム等の防火対象物に設置される煙監視システムにおいて、信号線を介して複数の従属型煙センサが接続されている煙警報盤200は、複数の警報レベルのうち煙センサにより測定された煙の濃度に応じた警報レベルを取得する取得部と、移報先に接続される接点を有する移報回路と、ユーザにより複数の警報レベルの中から選択された警報レベルを接点に割り当てる割当て部と、接点に割り当てられた警報レベルが取得部により取得されると、この接点の接続状態を切り替えて移報先に信号を出力するよう移報回路を制御する移報制御部と、を備える。【選択図】図3 |
