UNIT DESCRIPTION
The WattStopper DT-200 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 diffi cult
applications.
The DT-200 turns lighting systems on and off based on occupancy and ambient light
levels.
The DT-200 offers numerous operating modes that can be combined to create the
ideal custom control. The sensors can be confi gured 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 (5 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-200 operates on 24VDC supplied by WattStopper Power Packs. DT-200
sensors also have an isolated relay with Normally Open and Normally Closed
contacts for interfacing with HVAC or EMS.
COVERAGE PATTERN
The DT-200 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.
