1 / 2 page Agency Listings T-Tap Waterflow Detectors System Sensor T-Tap Waterflow Detectors are designed for primary signaling in residential systems and branch line signaling in larger systems. Features Sealed retard mechanism (Model WFDT) 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 100 percent synchronization activates both alarm panel and local bell Accommodates up to 12 AWG wire • • • • • • • • • Both the WFDT retard model and the WFDTNR non-retard model fit any tee that has a 1˝ NPT branch, including: 1˝, 1¼˝, 1½˝ and 2˝ NPT threaded ferrous and brass tees; 1˝, 1¼˝, 1½˝ and 2˝ copper sweat tees; Central, Spears®, and Victaulic® brand 1˝ CPVC tees; and 1½˝ 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˝, 1½˝, 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. S739 167-93-E 7770-1209:149 CS169 |
