Introducing the WFDN Series Waterflow Detector
from System Sensor.
WFDN Series Waterflow Detector is fully redesigned
to meet the needs of todayís fire sprinkler
professional. The new features of the timer dial,
cover, and terminal block add convenience and save
on installation time.
The new timer dial is a first for waterflow
detectors with a built-in time delay. Not only is it
large and easy to turn, but its high-contrast,
pad-printed markings and tactile features make it
easy to set by feel in dimly lit or hard-to-reach
locations. The detectorís built-in time delay
mechanism is still immune to dust and other
contaminants, but now itís also designed for
improved timer accuracy and repeatability.
directional cover is molded so it can only be
installed in one orientation, allowing the building
owner or installer to see the direction of waterflow
at a glance. The new non-metallic material is UV-
and damage-resistant, and it helps provide a better
seal while maintaining a NEMA 4 enclosure rating.
The cover also acts as an insulator, resists
corrosion and arching, and resists damage and
electric shock more effectively than current metal
designs on the market.
The wire-ready terminal block is designed for
intuitive wiring. The new terminal layout places the
common terminal on a different elevation, making it
easy to determine how to properly wire the switch.
The more robust paddle assembly allows the detector
to perform better in applications where a dramatic
in-rush of water causes a lot of vibration.
