The Flood Control Integrated System(FCIS) shall consist of a Reduced Pressure Principle Assembly (RP) (Model 375MS, 375AMS, 375ASTMS, or 975XL2MS), a Solenoid Control Valve(SCV) (Model ZW206), and an Electric Solenoid Timer (Model EST) and shall be constructed and tested at the factory as a complete assembly. The RP shall be certified to NSF/ANSI 372, and shall be ASSE 1013 Listed. The RP shall be furnished with full port, resilient seated shut-off valves, and shall be equipped with an integral Relief Valve Monitor Switch that monitors the Relief Valve in a closed position. The seat ring and the check valves shall be Noryl, the stems and springs shall be Stainless Steel, and the elastomers shall be EPDM. The SCV shall be a single seated, line-pressure-operated, diaphragm-actuated, pilot-controlled valve. The SCV shall seal by means of a corrosion resistant seat and a resilient, rectangular seat disc. The stem of the SCV shall be guided top and bottom by integral bushings, and shall contain no packing glands or stuffing boxes. The SCV shall be protected with internal and external FDA approved epoxy coating, and the diaphragm shall not be used as a seating surface. The EST shall have an input voltage of 120 VAC, and shall
be provided with outputs of 24 VAC and 120 VAC controlled by a user adjusted time delay relay. The EST shall be housed in a water-tight fiberglass NEMA enclosure, and shall have both normally open and normally closed outputs. The three components, the RP, SVC, and EST, when combined together, automatically shut off the water supply in the event of catastrophic relief valve discharge. The Reduced Pressure Principle Assembly, Solenoid Control Valve, and Electronic Solenoid Timer assembled as a complete unit shall be the Zurn Wilkins FCIS.
