Waterflow Detector Specifications <br /> Engineering Specifications <br /> Model shall be WFDNFS or WFDNFT as manufactured by System Sensor. Waterflow detectors shall be installed on a 1", 11/4"., 11/2".or <br /> 2".CPVC tee manufactured by Tyco,Spears,NIBBCO,or IPEX as designated on the drawing and/or as specified herein.Detectors shall <br /> mount on any clear pipe span of the appropriate nominal size,either a vertical upflow or horizontal run at least 6"from any fittings or valves <br /> that may change water direction,flow rate,or pipe diameter or no closer than 24in.from a valve or drain.Detectors shall have a sensitivity <br /> in the range of 4 to 10 gallons per minute and a static pressure rating of 175 psi.The WFDNFS or WFDNFT detector with incorporated <br /> time delay mechanism shall respond to waterflow in the specified direction after a preset time delay that is field adjustable.The delay <br /> mechanism shall be a sealed mechanical pneumatic unit with visual and audible indication of actuation.The actuation mechanism shall <br /> include a ethylene vinyl acetate vane inserted through a hole in the pipe and connected by a mechanical linkage to the delay mechanism. <br /> Outputs shall consist of dual SPDT switches(Form C contacts).Two conduit entrances for standard fittings of commonly used electrical <br /> conduit 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 /> Standard Specifications <br /> Static Pressure Rating 175 PSI Operating Temperature Range 32°F to 150°F(0°C to 60°C) <br /> Maximum Surge 18 Feet Per Second(FPS) Enclosure Rating* NEMA 4—suitable for indoor/outdoor use <br /> Triggering Threshold 4—10 GPM Cover Tamper Switch Optional,part no.CTS <br /> Bandwidth(Flow Rate) <br /> Conduit Entrances Two openings for thin.conduit.
