DT-300-U is BAA and TAA compliant (Product produced in the U.S.)
The WattStopper 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 difficult 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 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-300 operates on 24V supplied by WattStopper Power Packs. DT-300 sensors also have an isolated relay with Normally Open and
Normally Closed contacts for interfacing with HVAC or EMS.
The DT-300 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.
