The Model VSR-FE-2 is a vane type waterflow switch for use on wet sprinkler systems. It is UL Listed and FM Approved for use on steel pipe; schedules 10 thru 40, sizes 2" thru 8" (50mm - 200mm). The unit may also be used as a sectional waterflow detector on large systems.
The unit contains an output relay and an adjustable electronic retard. The relay is actuated when a flow of 10 gallons per minute (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.
The unit is 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 fi eld installable cover tamper switch is available as an option which may be used to indicate unauthorized removal of the cover.
