Waterflow switches used for this application may result in unintended discharges caused by surges, trapped air,or short retard times. Important: This document contains important information on the installation and operation of the VSR waterflow switches. Please read all instructions carefully before beginning installation. A copy of this document is required by NFPA 72 to be maintained on site. General Information Enclosure 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, systems.It is UL Listed for use on a steel pipe;schedules 5 through 40, die-cast housing. The cover is held in place with two tamper resistant sizes 2"-6"and is UL Listed and FM Approved for use on steel pipe; screws which require a special key for removal. A field installable schedules 10 through 40, sizes 2"thru 8"(50 mm thru 200 mm). LPC cover tamper switch is available as an option which may be used approved sizes are 2" thru 8" (50 mm thru 200 mm). See Ordering to indicate unauthorized removal of the cover. See bulletin number Information chart. 5401103 for installation instructions of this switch. The VSR may also be used as a sectional waterflow detector on large systems.The VSR 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 device. The flow condition must exist for a period of time necessary to overcome the selected retard period.
