System Sensor WFD50 WATERFLOW DETECTOR 5

Description

The System Sensor WFD50 is a waterflow detector for use with 5" pipe.

The System Sensor WFD series is compatible with schedule 10 through 40 steel pipes, sizes 2" through 8", and can be mounted in a vertical or horizontal position.

The WFD series consists of a rugged, NEMA 4-rated enclosure. Designed for both indoor and outdoor use, the WFD series operates across a wide temperature range, from 32°F 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 incorporates 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 retardÂ’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.
