WFD water flow detectors
WFDT retard and WFDNT non-retard t-tap waterflow detectors are designed for primary signaling in residential systems and branch line signaling in larger systems. Both models fit any tee that has a 1" npt branch, including: 1", 1-1 / 4", 1-1 / 2" and 2" npt threaded ferrous and brass tees; 1", 1-1 / 4", 1-1 / 2 and 2 copper sweat tees; Central, spears, and victaulic brand 1" cpvc tees; and 1-1 / 2" polybutylene tees.

Advantages:
Sealed retard mechanism (model WFDT)
Assures that the retard is not contaminated
By dust and dirt when the cover is removed.
Visual switch activation (model WFDT)
Permits installer to accurately set the retard even under extremely noisy conditions.
100% synchronization activates both alarm panel and local bell simultaneously accommodates up to 12 AWG wire.

Design:
The design of the WFDT and WFDTNR makes them easy to install and
Simple to maintain. Either can be mounted in the vertical or horizontal position.
Two conduit openings permit easy attachment to the local alarm system. The
Retard mechanism (model WFDT only) and switch assemblies are field-replaceable.

Features:
Twelve different flexible plastic paddles fit 1", 1-1 / 4", 11 / 2", 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.

Construction:
The WFDT and WFDTNR include a durable tamper resistant enclosure and rugged switch assembly. The long lasting covers completely enclose the electrical components to keep out dust and dirt. Improved self-guiding security screws and removal tools make detectors resistant to tampering and simplify field maintenance. Dual SPDT switches are enclosed in a durable terminal block for added strength.
