Zusammenfassung: | To allow an apparatus abnormality of a fire detector that has happened before the power source is input again to be recognized, even after a power source of a detector of an abnormality is input again.SOLUTION: An alarm system 1 has a master machine 10b and an alarm signal transmission device 20. The master machine 10b includes: a storage unit for storing state information of the master machine 10b; an initiation unit for initiating the state information so that the state information shows a normal state, when the power source of the master machine 10b is input again; a notification unit for notifying the alarm device 20 that the power source is input again when the power source is input again; and a transmission unit for sending state information to the alarm signal transmission device 20 at a predetermined timing. The alarm signal transmission device 20 includes: an alarm output unit for outputting an alarm signal to an external apparatus 30 according to the received state information; and a restriction unit for restricting processing in the alarm output unit according to the state information received within a predetermined length of time from when notifying that the power source is input again.SELECTED DRAWING: Figure 4
【課題】異常を検知する検知器の電源の再投入後においても、電源が再投入される前に発生した火災検知器の機器異常を認識できるようにする。【解決手段】警報システム1は、親機10bと、移報装置20とを備える。親機10bは、親機10bの状態情報を記憶する記憶部と、親機10bの電源が再投入されると、状態情報を正常状態を示すものに初期化する初期化部と、電源が再投入されると、電源の再投入を移報装置20に通知する通知部と、所定のタイミングで状態情報を移報装置20に送信する送信部とを有する。移報装置20は、受信された状態情報に応じて外部機器30に移報信号を出力する移報出力部と、電源の再投入が通知された時点から所定時間内に受信された状態情報に応じた移報出力部の処理を制限する制限部とを有する。【選択図】図4 |
