| Zusammenfassung: | To reduce a development cost in a case of increasing the number of output terminals and the number of connectable district acoustic devices to expand a model of a fire receiver.SOLUTION: While output terminals B 1 to B 5 are grouped in a fire receiver 10, the fire receiver comprises district acoustic control blocks 13#1 and 13#2 configured by a power supply circuit 11 for driving a district acoustic apparatus and a switch circuit 12 for controlling driving of the district acoustic apparatus by the power circuit with respect to each of the groups. The current circuit has different capacities according to the number of output terminals.SELECTED DRAWING: Figure 1
【課題】火災受信機を、出力端子の数や接続可能な地区音響装置の数を増やして機種展開しようとする場合の開発コストを抑える。【解決手段】火災受信機１０は、出力端子Ｂ１〜Ｂ５はグループ分けされており、そのグループの各々に対して、地区音響装置を駆動するための電源回路１１と、その電源回路による地区音響装置の駆動を制御するスイッチ回路１２とからなる地区音響制御ブロック１３＃１、１３＃２を備える。その電流回路は、その出力端子の数に応じて容量が異なる。【選択図】図１ |
