Waterflow switches used for this <br /> application may result in unintended discharges caused by surges, <br /> trapped air,or short retard times. <br /> General Information Enclosure <br /> The Model VSR is a vane type waterflow switch for use on wet sprinkler The VSR switches and retard device are enclosed in a general purpose, <br /> systems. It is UL Listed and FM Approved for use on steel pipe; die-cast housing. The cover is held in place with two tamper resistant <br /> schedules 10 through 40, sizes 2"thru 8"(50 mm thru 200 mm).LPC screws which require a special key for removal. A field installable <br /> approved sizes are 2" thru 8" (50 mm thru 200 mm). See Ordering cover tamper switch is available as an option which may be used <br /> Information chart. to indicate unauthorized removal of the cover. See bulletin number <br /> The VSR may also be used as a sectional waterflow detector on large 5401103 for installation instructions of this switch. <br /> systems.The VSR contains two single pole.double throw,snap action <br /> switches and an adjustable, instantly recycling pneumatic retard. The <br /> switches are actuated when a flow of 10 GPM(38 LPM)or more occurs <br /> downstream of the device. The flow condition must exist for a period <br /> of time necessary to overcome the selected retard period. <br /> .4111 <br /> Potter Electric Signal Company, LLC • St. Louis, MO • Phone: 866-956-1211/Canada 888-882-1833 • www.pottersignal.com <br /> PRINTED iN USA MFG.#5401146-REV L PAGE I OF 4 <br /> 3/09 • <br />
