Occupancy Sensor
Multi-Technology Ceiling Sensor
OSC20-MOW
OSC10-MOW
OSC05-MOW
The most advanced sensor available.
Combines multi-technology with all-digital
architecture. Eliminates false triggering. The
result is a trouble-free, “install and forget”
solution for lighting control.
THE OSCxx-MOW SERIES OCCUPANCY SENSOR
• MULTI-TECHNOLOGY FOR HIGHEST RELIABLITY
INFRARED & ULTRASONIC
• SIMPLE, FAST INSTALLATION
• SELF-ADJUSTING
• ALL-DIGITAL, COMPLETE RELIABILITY
• PHOTOCELL BUILT-IN
• CEILING MOUNT
GENERAL OPERATION
Occupancy sensors have two tasks: keeping the lights on
while the room is occupied and, conversely keeping the
lights off when unoccupied. Ultrasonic (doppler shift)
motion detection gives maximum sensitivity yet can be
vulnerable to false triggering from air conditioning
currents, corridor activity and movement of inanimate
objects. Infrared motion sensing gives immunity to false
triggering, but lacks sensitivity at greater distances.
Leviton multi-technology sensors combine the benefits
of both infrared and ultrasonic technologies for unrivaled
performance and reliability.
ADAPTIVE FUNCTIONS
The OSCxx-MOW constantly analyzes and adapts to changing conditions
Corridor Activity
Air
Currents
Inanimate
objects
When unoccupied, lights stay off while air conditioning sys-
tem cycles on and off, and cleaning crews occupy corridors.
Upon room entry, the
infrared detects motion
and turns lights on.
Ultrasonic keeps lights on
even with very minor motion.

SPECIFICATION SUBMITTAL
Timer Left In Test Mode - The
sensor remains in an 6 sec.
test mode.
False-On - The sensor
incorrectly turns the lights on.
False-Off - The sensor
incorrectly turns the lights off.
An installer accidentally leaves
the sensor in the 6 sec. timer
test mode and the lights may go
off or on every 6 sec.
The sensor detects movement
in the corridor or hallway and
the room lights turn on.
The sensor does not detect
movement because an
occupant sits virtually
motionless at a desk and the
lights turn off.
The sensor automatically resets the timer
to 10 min . after 15 min of test mode..
After an initial movement is sensed,
if another movement is not sensed within
the timer setting then the delayed off time
setting is automatically reduced.
Condition Example Adaptive Reaction
If motion is sensed within a short period after
the lights go off, then the current delayed
off-time setting is increased.
