System Sensor T-Tap Waterflow Detectors are designed
for primary signaling in residential systems and branch
line signaling in larger systems.
Features

• Visual switch activation (Model WFDT)
• Twelve different flexible plastic paddles
• Vertical or horizontal mount
• Durable tamper resistant enclosure
• Dual SPDT switches in durable terminal block
• Sizes marked on flexible plastic paddles

Both the WFDT retard model and the WFDTNR non-retard model fit
any tee that has a 1˝ NPT branch, including: 1˝, 1¼˝, 1�½˝ and 2˝ NPT
threaded ferrous and brass tees; 1˝, 1¼˝, 1�½˝ and 2˝ copper sweat
tees; Central, Spears

polybutylene tees.
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˝, 1¼˝, 1�½˝, and
2˝ tees. Sizes are marked clearly on the paddles 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.
