Unit Description; Coverage Pattern - wattstopper DT-355 Installation Instructions Manual

UNIT DESCRIPTION

The WattStopper DT-355 360° 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-355 turns lighting systems on and off based on occupancy and ambient
light levels. The light level feature can be used to keep lights from turning on if
the ambient light level is sufficient.
SmartSet™ technology allows the sensor to be installed with minimal
adjustments. SmartSet automatically adjusts the time delay and PIR sensitivity
to usage patterns in the controlled space.
The DT-355 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 user-specified time or the SmartSet time (5 to 30
minutes) the lights are switched off. A "walk-throug h" mode can turn lights off
after only 3 minutes, if no activity is detected after 30 seconds of an occupancy
detection.
The DT-355 operates on 120VAC, 230VAC, 277VAC, or 347VAC line voltage.

COVERAGE PATTERN

The DT-355 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.
