UNIT DESCRIPTION
The WattStopper DT-305 360° Dual Technology occupancy sensors combine
advanced passive infrared (PIR) and ultrasonic technologies into one unit. The
combination of these technologies helps to eliminate false triggering problems even
in difficult applications.
The DT-305 turns lighting systems on and off based on occupancy. The DT-305
provides numerous operating modes that can be combined to create the ideal
custom control. The sensors can be configured to turn lighting on, and hold it on
as long as either or both technologies detect occupancy. After no movement is
detected for a user specified time (30 seconds to 30 minutes) the lights are switched
off. A "walk-through" mode can turn lights off after only 3 minutes, if no activity is
detected after 30 seconds of an occupancy detection.
The DT-305 operates on 24V supplied by WattStopper Power Packs.
COVERAGE PATTERN
The DT-305 provides a 360° coverage pattern. The coverage shown represents
walking motion at a mounting height of 10 feet. For building spaces with lower levels
of activity or with obstacles and barriers, coverage size may decrease. The coverage
for PIR ONLY trigger mode varies with mount height. Refer to pattern below for
details. Ultrasonic coverage is roughly the same for 8-12 foot mount heights. Refer
to PIR and Ultrasonic trigger mode coverage for details.
