The model VSR-S is a vane type waterflow switch for use on wet sprinkler systems that use 1 in (25mm), 1-1/4 in (32mm), 1-1/2 in (38mm) or 2 in (50mm) pipe size. The unit may also be used as a sectional waterflow detector on large systems. The unit contains 2-single pole double throw snap action switches and an adjustable, instantly recycling pneumatic retard. The switches are actuated when a flow of 10 gpm or more occurs downstream of the device. The flow condition must exist for a period of time necessary to overcome the selected retard period.
