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 covec See bulletin number <br /> The VSR may also be used as a sectional waterfiow detector on lazge 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 /> Potter Electric Signal Company, LLC • St. Louis, MO • Phone• 866-956-12ll/Canada 888-882-1833 • www pottersignal.com <br /> PRINTED 1N USA MFG.#5401146-REV L PAGE 1 OF 4 <br /> 3/09 <br />
