The model VSR-SG is a vane type waterflow switch for use on wet sprinkler systems using CPVC plastic fittings (manufactured by Tyco, Nibco, Victaulic, Ipex and Spears Manufacturing Company) that use 1 in, 1-1/4 in, 1-1/2 in or 2 in pipe sizes. It is equipped with a union to accommodate installation in confined spaces. The VSR-SG 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 switch. The flow condition must exist for a period of time necessary to overcome the selected retard period.
