{"product_id":"potter-vsr-sg-vane-type-waterflow-alarm-switch","title":"Potter VSR-SG Vane Type Waterflow Alarm Switch","description":"The Model VSR-SG is a vane type waterflow switch for use on wet sprinkler systems using CPVC plastic fittings (manufactured by Tyco, Nibco, Victaulic, Ipex, and Spears Manufacturing Company) that use 1”, 1 ¼”, 1 ½”, or 2” pipe sizes. It is equipped with a union to accommodate installation in confined spaces.\n\nThe VSR-SG 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 GPM (38 LPM) or more occurs downstream of the switch. The flow condition must exist for a period of time necessary to overcome the selected retard period.\n\nThe VSR-SG switches and retard switch 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\u003eUL, CUL and CSFM Listed, CE Marked\u003c\/li\u003e\n  \u003cli\u003eService Pressure: Up to 175 PSI (12,07 BAR)\u003c\/li\u003e\n  \u003cli\u003eFlow Sensitivity Range for Signal: 4-10 GPM (15-38 LPM) – UL\u003c\/li\u003e\n  \u003cli\u003eMaximum Surge: 18 FPS (5.5 m\/s)\u003c\/li\u003e\n  \u003cli\u003eContact Ratings: Two sets of SPDT (Form C), 10.0 Amps at 125\/250VAC, 2.0 Amps at 30VDC Resistive, 10 mAmps min. at 24VDC\u003c\/li\u003e\n  \u003cli\u003eConduit Entrances: Two openings provided for 1\/2\" conduit.
