Overview
For reliable, code-compliant detection of sprinkler water movement, the Potter Electric Signal, LLC VSR-S vane type waterflow alarm switch delivers precise, field-proven performance for wet sprinkler systems and sectional detection on large risers. The VSR-S actuates at 10 gallons per minute and fits common 1" to 2" pipe sizes, giving you straightforward compatibility with CPVC, copper, brass or iron piping. Its adjustable 0–90 second pneumatic retard reduces false alarms by requiring sustained flow before signaling, while two SPDT (Form C) contacts let you integrate directly with fire alarm panels, security monitoring or BMS platforms. The rugged die-cast housing uses tamper-resistant screws and offers an optional cover tamper switch for added physical security and auditability. Designed for quick field setup — including easy-to-read retard adjustment and terminal designations — the VSR-S lowers installation time and maintenance effort. Ideal for fire protection contractors, facilities managers and security integrators who need dependable waterflow monitoring that supports surveillance and alarm systems. Specify the VSR-S for your next wet sprinkler project or contact us for application support and ordering.
