DESCRIPTION AND OPERATION
The Wattstopper DT-205 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-205 turns lighting systems on and off based on occupancy. It offers 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 the duration of the time delay (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-205 operates on 24VDC supplied by Wattstopper Power Packs.

COVERAGE PATTERN
The DT-205 provides an eliptical 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.
