Potter – VSR-ST Waterflow Alarm Switch with Union – in Saudi Arabia

Elite Fire Trading Company is the authorized distributor of Potter products in Saudi Arabia, offering advanced fire protection solutions such as the VSR-ST Waterflow Alarm Switch with Union. The VSR-ST is a reliable vane-type waterflow switch designed for use on wet sprinkler systems with pipe sizes ranging from 1″ to 2″. Its unique feature is the union design, which makes it ideal for installation in confined spaces where standard switches may not fit.

The VSR-ST includes two single-pole double-throw snap-action switches and an adjustable pneumatic retard, which helps to prevent false alarms due to temporary water pressure variations. This switch activates when 10 GPM (38 LPM) or more of water flows downstream, ensuring that alarms are only triggered when needed. The retard feature ensures that the flow condition persists long enough to confirm the alarm’s validity.
