保特potter開關接在閥門水流報警接口配管上，根據水流監測閥門是否開啟。僅需一個灑水頭動作的流量壓力開關就可動作。在預作用系統中接在閥門出口處，監測系統管道中氣壓，當氣壓降低時，發出低氣壓報警信號。動作壓力能在4-20psi (0.28-1.38bar) 之間調節。開關必須直立安裝。 保特PS10A 系列是壓力型水流探測開關，分為PS10-1A ( 含一副SPDT 接點)，PS10-2A( 含二副SPDT 接點)，在濕式、干式和預作用系統中。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系列壓力驅動開關設計用于檢測特定設計的自動噴水滅火系統中的水流狀況，例如帶報警止回閥，干管，預作用或雨淋閥的濕管系統。FM認證壓力開關 PS10也適用于提供低壓監控信號; 可在4到15 psi（0,27和1,03 BAR）之間調節。
