COMMERCIAL OCCUPANCY SENSORS & CONTROLS
UW-100 Ultrasonic Wall Switch Sensor
Low profile design
High sensitivity for
exceptional performance
• Detection Signature Processing eliminates false
triggers and provides immunity to RFI and EMI
• Zero-crossing for long relay life
• Choice of Auto-ON or Manual-ON operation
• Selectable walk-through mode turns lights off
three minutes after the room is initially occu-
pied if no motion is detected after the first 30
seconds
• Test mode allows quick and easy adjustments
• Selectable audible and/or visual alerts for
impending shutoff
The UW-100 ultrasonic wall switch sensor turns
lights ON and OFF based on occupancy. It is
characterized by high sensitivity to small and large
movements, appealing aesthetics, and a variety of
features.
Auto Set
Applications
The UW-100 sensor is ideal for applications where
the sensor may have a partially obstructed line
of sight on the occupant. Common applications
include individual restrooms, restrooms with two
stalls and utility/storage rooms.
Operation
The UW-100 fits in a single junction box. It uses
high frequency (40kHz) ultrasound to detect occu-
pancy and turn lighting ON. Once the space is
vacated and the time delay elapses, lights auto-
matically turn OFF. DIP switch settings allow for
a variety of control options such as Auto-ON or
Manual-ON operation, walk-through, and test
modes.
Description
Product
Overview
Features
• In automatic mode, sensor returns auto-
matically to Auto-ON after lights are turned off
manually; ideal for presentations
• LED indicates occupancy detection
• Optional light level sensing with simple setup
• Override mode allows sensor to operate as a
service switch in the unlikely event of a failure
• Sensor coverage tested to NEMA Guide
Publication WD 7-2000
Part of a comprehensive line of PIR,
Ultrasonic and Dual Technology wall
switch sensors
Selectable auto set, walk-through, test
and presentation modes for increased
energy savings and convenience
With auto set enabled, the UW-100 continuously
monitors the controlled space to identify usage
patterns and automatically adjust the time delay
for optimal energy efficiency. The sensor assigns
short delays (as low as seven minutes) for times
when the space is usually vacant, and longer
delays (up to 30 minutes) for busier times. Auto set
is also able to differentiate electrical noise from
human motion for better performance.
