Claims (1)
かれることによる検出用圧縮空気管の圧力低下を
圧力スイツチで検出して信号を出力する空気圧式
緊急警報装置において、上記空気管に適宜間隔で
挿入された区分用オリフイスと、上記区分用オリ
フイスによりほぼ仕切られた上記空気管の小区画
にそれぞれ付設された上記圧力スイツチとを具え
たことを特徴とする空気圧式緊急警報装置。 In a pneumatic emergency alarm device that uses a pressure switch to detect a pressure drop in a detection compressed air pipe due to opening of an attached manual relief valve or fusible plug and outputs a signal, a pressure switch is inserted into the air pipe at appropriate intervals. A pneumatic emergency alarm device comprising: a dividing orifice; and the pressure switch attached to each of the small sections of the air pipe substantially partitioned by the dividing orifice.
