System Sensor WFDTH T-Tap Waterflow Detector

The WFDTH is a T-Tap waterflow detector for use with a 1" NPT connection, in residential sprinkler systems. The WFDTH fits any tee that has a 1 NPT branch, including: 1, 1, 1, and 2 NPT threaded ferrous and brass tees; 1, 1, 1 and 2 copper sweat tees; Central, Spears , and Victaulic brand 1 CPVC tees; and 1 polybutylene tees.

The design of the WFDTH makes it easy to install and simple to maintain. It can be mounted in the vertical or horizontal position. Two conduit openings permit easy attachment to the local alarm system. The retard mechanism and switch assembly are field-replaceable.

Twelve different flexible paddles fit 1, 1, 1, and 2 tees. Sizes are marked clearly on the paddle for ease of installation. Plastic paddles slip over the actuating lever and are securely fastened with one screw. The handy depth gauge insures the proper installation depth and clearance of the detector to the tee.

The WFDTH includes a durable and tamper resistant enclosure. Its sealed retard assures that the delay mechanism is not contaminated by dust and dirt when the cover is removed. The long lasting cover completely encloses the electrical components to further keep out dust and dirt. Improved self-guiding security screws and removal tools make detectors resistant to tampering and simplify field maintenance.
