UNIT DESCRIPTION
The Watt Stopper DT-300 360° 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 diffi cult applications.
The DT-300 turns lighting systems on and off based on occupancy. The DT-300
provides 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 a user specifi ed or SmartSet time (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-300 operates on 24V supplied by Watt Stopper Power Packs. DT-300 sensors
also have an isolated relay with Normally Open and Normally Closed contacts for
interfacing with HVAC or EMS.
COVERAGE PATTERN
The DT-300 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.
