General Information
The Model VSR 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 through 40, sizes 2" thru 8" (50 mm thru 200 mm). LPC approved sizes are 2" thru 8" (50 mm thru 200 mm). 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.

Enclosure
The VSR switches and retard device 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.

In most cases, the installation or expansion of a commercial fire alarm system is determined by code requirements. There is federal, state, and local codes that come into play, specifying who must install fire alarm equipment, what type of equipment must be installed, where and how it must be installed. Failing to comply fully with any of these codes can result in denial of occupancy permits, fines, legal and financial liability.

Sorry we do not offer technical support for these products because of local codes that come into play specifying who must install fire alarm equipment and where and how it must be installed. To read more, visit the National Fire Alarm and Signaling Code website.
