The WFDTH fits 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˝

and 1½˝ polybutylene tees.

Design. 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.

Features. Twelve different flexible paddles fit 1˝, 1¼˝, 1½˝, 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 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.
