Robust Construction.
The WFDE series consists of a rugged, IP54
rated enclosure. Designed for both indoor and outdoor use, the
WFDE series operates across a wide temperature range, from 0°C to
68°C (32°F to 155°F).
Reliable Performance.
WFDE models are equipped with tamper-
resistant cover screws to prevent unauthorized entry. Inside, two sets
of SPDT (Form C) synchronized switches are enclosed in a durable
terminal block to ensure reliable performance.
False Alarm Immunity.
The WFDE series incorporates a
mechanical retard feature, which minimizes the risk of false alarm
due to pressure surges or air trapped in the sprinkler system. In
addition, the mechanical retard’s unique sealed design is immune
to dust and other contaminants.
Simplified Operation.
The WFDE series is designed to simplify
installation. Two conduit openings permit easy attachment to the
local alarm system. The retard mechanism and dual SPDT switches
are field-replaceable.
