Pipe Size\n\nThe Model VSR-S is a vane type waterflow switch for use on wet sprinkler systems that use 1” (25mm), 1¼” (32mm), 1½” (38mm) or 2” (50mm) pipe size. The unit may also be used as a sectional waterflow detector on large systems.\n\nThe unit contains two single pole double throw snap action switches and an adjustable, instantly recycling pneumatic retard. The switches are actuated when a flow of 10 gallons per minute (38 LPM) or more occurs downstream of the device. The flow condition must exist for a period of time necessary to overcome the selected retard period.\n\nThe VSR-S switches and retard device are enclosed in a general purpose, die-cast housing. The cover is held in place with two tamper resistant screws which require a special key for removal. A field installable cover tamper switch is available as an option which may be used to indicate unauthorized removal of the cover.\n\u003ch4\u003e\u003cstrong\u003eMain Features\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAssembled in USA\u003c\/li\u003e\n  \u003cli\u003e0-90 second field replaceable time delay retard\u003c\/li\u003e\n  \u003cli\u003eEasy to read retard time delay adjustment knob\u003c\/li\u003e\n  \u003cli\u003eFits 1” to 2” CPVC, copper, brass, or iron pipe\u003c\/li\u003e\n  \u003cli\u003eComes with all necessary paddles\u003c\/li\u003e\n  \u003cli\u003eTwo SPDT (form C) contacts\u003c\/li\u003e\n  \u003cli\u003eWeatherproof\u003c\/li\u003e\n  \u003cli\u003eEasy to read wire terminal designations\u003c\/li\u003e\n  \u003cli\u003e5 year warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Potter","offers":[{"title":"Default Title","offer_id":43250692390977,"sku":"PL-VSRS","price":169.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0700\/2465\/9009\/files\/7002634b-pl-vsrs_lg.jpg?v=1770771306","url":"https:\/\/www.fireandsafetyplus.com\/products\/potter-vsr-s-vane-type-waterflow-alarm-switch","provider":"Fire and Safety Plus","version":"1.0","type":"link"}
