PRODUCT DATA
OSCxx-M0W
Multi-Technology Ceiling
Occupancy Sensor
BASIC OPERATION
Occupancy sensors have two tasks: 1) Keeping the
lights ON while the room is occupied, and 2) Saving
energy by keeping the lights OFF while the room is
unoccupied.
Passive Infrared (PIR) is an excellent and precise
technology for initially turning the lights ON, but lacks
sensitivity for minor motion at distances. Ultrasonic
(U/S) technology provides maximum sensitivity with
continuous reflective high frequeny waves. This is
opitmal for keeping the lights ON.
Leviton’s multi-technology sensor combines the
benefits of both PIR and U/S technologies for unri-
valed performance and reliability.
APPLICATIONS
• Cafeterias • Classrooms
• Computer rooms • Conference rooms
• Day care centers • Filing rooms
• Workspaces • Open warehouses
• Offices with cubicles • Open areas
• Restrooms • Stairwells
• Storage rooms • Executive, open,
and private offices
Timer Left In Test Mode - The
sensor remains in an 6 sec.
test mode.
False-On - The sensor
incorrectly turns the lights on.
False-O - The sensor
incorrectly turns the lights o.
An installer accidentally leaves
the sensor in the 6 sec. timer
test mode and the lights may go
o or on every 6 sec.
The sensor detects movement
in the corridor or hall way 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 o.
The sensor automatically resets the timer
to 10 min . after 15 min of test mode.
After an initial movement is sensed,
if another mov ement is not sensed within
the timer setting then the delayed o time
setting is automatically reduced.
Condition Example Self-Adaptive Reaction
If motion is sensed within a short period after
the lights go o, then the current delayed
o-time setting is increased.
HOW THE OSCxx-M AUTOMATICALLY ADAPTS
FEATURES
• Self-Adjusting: Internal microprocessor con tin u al ly
analyzes, evaluates and adjusts the sensitivity and
time delay. Performance is kept at a maximum and
user complaints are eliminated.
• Custom off-white color matched for shaded ceilings.
• Fast, Simple In stal la tion: Easy ceiling mount, three
wire con nec tion (low voltage) and twist-lock sen-
sor attachment for 360° rotation and flexibility.
• Maximum Reliability, Low Cost: digital circuitry uses
a minimum of components.
• Small Motion Sensitivity: The ultrasonic tech nol o gy
provides excellent small motion sensitivity.
• Timer Setting Feature: Automatic – 30sec – 30min.
Test mode – 6sec with auto exit programming.
• Non-Volatile Memory: Learned and adjusted set-
tings
saved in protected memory are not lost dur-
ing power outages.
• Walk-Through: Provides increased energy savings
by decreasing the time delay to 2.5min when some-
one momentarily walks through the monitored
space.
• Wide Coverage: Units from 500 to 2000 sq. ft. avail-
able.
• Power base (OPB 15) available for line voltage appli-
cations
• Ambient Light Recognition: A Light Sensor prevents
lights from turning on when the room is adequately
lit by natural light.
• Ultrasonic (U/S) Components: One or two U/S
transducers and one or two narrow bandwidth
receivers each 16mm in diameter. Frequency --
Crystal controlled to ±.005%.
• Device: Rug ged, high-im pact, in jec tion molded plas-
tic, off -white. Col or coded leads 6” (16.24 cm).
