A water flow detector is an electro-mechanical device designed to send an alarm to a fire alarm panel and/or fire department when a continuous flow of water occurs through the fire sprinkler system's piping from an activated sprinkler head or leak in the system.
The Model VSR is a vane type waterflow switch for use on wet sprinkler systems. 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.
