Product Details

Product Overview

The Potter VSR is a vane type waterflow alarm switch that detects water flow in wet pipe sprinkler systems and signals the fire alarm panel. A field replaceable retard with an easy-to-read adjustment knob delays the alarm from 0 to 90 seconds to avoid false alarms from pressure surges. The manufacturer warns that waterflow switches on wet systems must not be the sole initiating device for discharging AFFF, deluge or chemical suppression systems.
