WFDN Series waterflow detectors use a tough NEMA 4-rated enclosure that resists damage better than earlier metal designs, and they are rated for indoor and outdoor use from 32°F to 150°F.\u003c\/p\u003e\u003cp\u003eA mechanical time delay helps prevent false alarms from pressure surges or air trapped in the sprinkler system. The large timer dial has high-contrast markings, a larger tab at roughly 60 seconds and a notch at roughly 30 seconds, which makes it easier to set in poorly lit areas.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTwo synchronized SPDT (Form C) switches in a terminal block laid out for easy wiring\u003c\/li\u003e\n\u003cli\u003eCOM terminals on a separate level, a large barrier between switches and raised lettering\u003c\/li\u003e\n\u003cli\u003eUL-listed models have tamper-resistant cover screws\u003c\/li\u003e\n\u003cli\u003eOptional cover tamper switch snaps in without tools\u003c\/li\u003e\n\u003cli\u003eDesigned for accurate, repeatable operation and better vibration performance in risers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eWFD25N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eVane-type waterflow detector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePipe size\u003c\/td\u003e\n\u003ctd\u003e2.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries pipe schedules\u003c\/td\u003e\n\u003ctd\u003e2\" through 4\" sizes approved for schedules 7 through 40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSwitches\u003c\/td\u003e\n\u003ctd\u003e2 x SPDT (Form C), synchronized\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure\u003c\/td\u003e\n\u003ctd\u003eNEMA 4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating temperature\u003c\/td\u003e\n\u003ctd\u003e32°F to 150°F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUse\u003c\/td\u003e\n\u003ctd\u003eIndoor and outdoor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTime delay\u003c\/td\u003e\n\u003ctd\u003eMechanical, adjustable dial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"System Sensor","offers":[{"title":"Default Title","offer_id":68073076981973,"sku":"WFD25N","price":272.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/5826\/3253\/files\/712CP998ezL._AC_SL1500.jpg?v=1793582794","url":"https:\/\/fireservicesgroup.com\/products\/system-sensor-wfd25n-2-5-waterflow-detector","provider":"FSG - Fire Services Group","version":"1.0","type":"link"}
