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 8-12 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.
