Engineering Specifications • <br /> Vane-type waterflow detectors shall be installed on system piping as designated on the drawing and /or as specified herein. <br /> from any fittings which may change water direction, flow rate, or pipe diameter or no closer than 24" from a valve or drain. Detectors <br /> shall have a sensitivity in the range of 4 to 10 gallons per minute and a static pressure rating of 450 psi for 2" - 8" pipes. The <br /> detector shall respond to waterflow in the specified direction after a preset time delay which is field adjustable. The delay mecha- <br /> nism shall be a sealed mechanical pneumatic unit with visual indication of actuation. The actuation mechanism shall include a <br /> consist of dual SPDT switches (Form C contacts). Two conduit entrances for standard fittings of commonly used electrical conduit <br /> shall be provided on the detectors. A grounding provision is provided. Unless noted, enclosures shall be NEMA 4 listed by <br /> Underwriters Laboratories Inc. All detectors shall be listed by Underwriters Laboratories Inc. for indoor or outdoor use. <br /> Static Pressure Rating Conduit Entrances Service Use <br /> 450 PSI Two openings for 1/2" conduit.
