Product Details
Product Overview The Potter VSR-6 is a vane-type waterflow switch designed for wet sprinkler systems. It features two single-pole, double-throw (SPDT) snap-action switches with an adjustable, instantly recycling pneumatic retard. The switches activate when water flow of 10 GPM (38 LPM) or more occurs downstream, ensuring proper signaling in compliance with NFPA-13 standards. The device is suitable for both sectional and standard sprinkler systems and is UL Listed, FM Approved, CUL Listed, CSFM Listed, and LPCB Approved.
