Type
Integrated photocell prevents lights
from turning ON when the room is
adequately illuminated by natural light
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.
Features
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
Switches at the zerocrossing point of the AC
power curve to ensure
maximum contactor life
and compatibility with
electronic ballasts
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

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-MediumHigh. This feature makes the OSW-DT perfect for a wide variety of
room sizes and configurations.

How the OSW-DT Automatically Adapts
Condition
Example
Adaptive Reaction
False-ON: The sensor
incorrectly turns the
lights ON
The sensor detects
movement in the corridor or
hallway and the room lights
turn on
Afer an initial movement is
sensored, if another movement is
not sensed within the timer setting
then the delayed off-time setting is
automatically reduced
False-OFF: The sensor The sensor does not detect
incorrectly turns the
movement, because an
lights OFF
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
