保特potter开关接在阀门水流报警接口配管上，根据水流监测阀门是否开启。仅需一个洒水头动作的流量压力开关就可动作。在预作用系统中接在阀门出口处，监测系统管道中气压，当气压降低时，发出低气压报警信号。动作压力能在4-20psi (0.28-1.38bar) 之间调节。开关必须直立安装。 保特PS10A 系列是压力型水流探测开关，分为PS10-1A ( 含一副SPDT 接点)，PS10-2A( 含二副SPDT 接点)，在湿式、干式和预作用系统中。The Potter PS10 Series Pressure Actuated Switches are designed for the detection of a waterflow condition in automatic fire sprinkler systems of particular designs such as wet pipe systems with alarm check valves, dry pipe, preaction, or deluge valves. The PS10 is also suitable to provide a low pressure supervisory signal; adjustable between 4 and 15 psi (0,27 and 1,03 BAR).
Potter PS10系列压力驱动开关设计用于检测特定设计的自动喷水灭火系统中的水流状况，例如带报警止回阀，干管，预作用或雨淋阀的湿管系统。FM认证压力开关 PS10也适用于提供低压监控信号; 可在4到15 psi（0,27和1,03 BAR）之间调节。
