turning ON when the
room is adequately
illuminated by natural
light.
Switches at the zerocrossing point of the AC

The ultrasonic
technology provides
excellent minor
motion sensitivity.
• Time delay and sensitivity settings
are continually adjusted to occupant
patterns of use in auto adapt mode
• Provides increased energy savings by
not leaving the lights ON for an
extended period after only momentary
occupancy
• Provides ManualON/OFF light
switching at any time
• Fits in a standard wall box and
replaces a single pole wall switch and
can be ganged together with other
units in a multiple switch wallplate
• May be adjusted between 180° and
32° of arc by using integral blinders
located on either side of the lens
• Allows customized adjustments to
maximize energy savings
• NEMA WD7 Guide robotic method
utilized to varify coverage patterns

Overview
The OSW-DT, Dual Tech Wall Switch Occupancy Sensor is used to provide
automatic lighting control for energy savings and convenience in a variety of
commercial applications. The OSW-DT provides for automatic switching of
incandescent lamps, low voltage lighting with electronic and magnetic
transformers, and electronic and magnetic fluorescent ballasts. The OSW-DT
features a manual override switch that can be used to keep lights ON while an
area is occupied, which may be desired in conference rooms, classrooms and
other areas during video presentations. Designed to replace a single pole
Decorator wall switch, it fits in a standard wall box.
Operation
Greengate's OSW-DT combines Ultrasonic and Passive Infrared (PIR) sensor
technology to monitor a room for occupancy to deliver unrivaled performance
and reliability. The PIR is used to detect motion and turn lights ON, while either
technology is used to keep lights ON while occupied. This allows the Ultrasonic
to be set to higher sensitivity levels minimizing false OFF conditions. The PIR
portion gives immunity to false ON through a specialized lens which divides the
field of view into sensor zones. When a person passes into or out of a sensor
zone, the sensor detects motion and switches the lights ON. The Ultrasonic
sensors give maximum sensitivity and range in difficult spaces with irregular
shaped rooms and partitions that can block the PIR field of view. The Ultrasonic
sensors will detect Doppler shifts caused by motion in a space. These sensors
are more sensitive to small movements since they do not rely on zones.
Sensitivity can be field adjusted to Low-Medium-High. This feature makes the
OSW-DT perfect for a wide variety of room sizes and configurations.

Three-way wiring diagram: Lights will turn-off automatically when sensor that

Coverage
The NEMA WD 7 Guide and robotic method were utilized to verify coverage patterns.
False-ON: The sensor
incorrectly turns the
lights ON.
The sensor detects movement
in the corridor or hallway and
the room lights turn on.
False-OFF: The sensor
incorrectly turns the
lights OFF.
The sensor does not detect movement, because an occupant sits
motionless at a desk and the
lights turn OFF.
If motion is needed within a short period after the
lights go OFF, then the current delayed off-time
setting is increased.
