Water Detectors
WFD Series Waterflow Detector
WFD Series water flow detectors are compatible with schedule 10 through 40 steel pipe, sizes 2 through 8 inch, and can be mounted in a vertical or horizontal position.
WFD Series water flow detectors are compatible with schedule 10 through 40 steel pipe, sizes 2 through 8 inch, and can be mounted in a vertical or horizontal position. WFD Series detectors consist of a rugged, NEMA 4-rated enclosure. Designed for both indoor and outdoor use, WFD Series detectors operate across a wide temperature range, from 32 to 120 °F.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 to assure reliable performance. The WFD Series detectors incorporate a mechanical retard feature, which minimizes the risk of false alarm due to pressure surges or air trapped in the sprinkler system. In addition, the mechanical retard’s unique sealed design is immune to dust and other contaminants. The WFD Series is designed to simplify installation. Two conduit openings permit easy attachment to the local alarm system. The retard mechanism and dual SPDT switches are field-replaceable.
