WFDNF water flow detectors are designed for primary signaling in systems that use CPVC fittings. WFDNF water flow detectors consist of a rugged, NEMA 4 rated enclosure that is more damage resistant than previous metal designs. The water flow detector is designed for both indoor and outdoor use, with the widest available temperature range, from 32 to 150 °F. Clearly marked plastic paddles are included to fit different installation configurations. UL-listed models are equipped with tamper-resistant cover screws to prevent unauthorized entry. Inside, two sets of SPDT (Form C) synchronized switches are enclosed in a durable terminal block with a layout designed to make wiring easy. The wire-ready COM terminals are on a different elevation with a large barrier between switches and easy-to-read, raised, textured lettering. An optional cover tamper switch securely snaps into place, no tools required. WFDNF detectors incorporate a mechanical time delay feature that minimizes the risk of false alarms due to pressure surges or air trapped in the fire sprinkler system. The large and easy-to-turn timer dial makes setting the water flow detector easy with high-contrast, pad-printed markings. The dial offers three tabs to help with turning: the largest tab is located on the dial position for approximately 60 seconds and a notch in the dial indicates approximately 30 seconds, making the detector easy to set in dimly lit locations. The detectors are designed for accuracy and repeatability. They also offer improved performance during vibration in riser applications where detectors are exposed to a large in-rush of water. Features & Benefits:

Directional cover allows installers and inspectors to easily see the direction of flow

UL-listed models are NEMA 4/IP 54 rated

Cover is lightweight, unpainted, and corrosion resistant

Sealed retard mechanism immune to dust and other contaminants

Less exposed metal reduces shock hazard, plastic cover acts as insulator and is resistant to arcing
