PRODUCT DATA
OSCxx-UOW
Ultrasonic Ceiling Occupancy Sensor
BASIC OPERATION
The OSCxx-U is a low voltage occupancy sensor that
controls indoor lighting. The sensor fills the room
with continuous reflective high frequency (ultrasonic)
sound waves. Any movement within the sensor’s
range causes a shift in the original emitted frequency.
T
he sensor’s receiver identifies any change in frequency
as motion and either turns the lights on or maintains
lights on.
APPLICATIONS
• Cafeterias • Classrooms • Hallways
• Filing rooms • Open areas • Restrooms
• Storage rooms • Open warehouses
• Workspaces • Executive offices
• Offices with cubicles
FEATURES
• Self Adjusting: An internal microprocessor automati-
cally analyzes, evaluates and adjusts time delay and
U/S settings for maximum energy savings
• 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 sensor
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.
• Non-Volatile Memory: Learned and adjusted settings
saved in protected memory are not lost during
power outages.
•
Timer Setting Feature: Automatic – 30sec – 30min.
Test mode – 6sec with auto exit programming
• Walk-Through: Provides increased energy savings by
decreasing the time delay to 2.5min when someone
momentarily walks through the monitored space.
• Wide Coverage: Units from 500 to 2000 sq. ft. available.
• Ambient Light Recognition: A Light Sensor prevents
lights from turning on when the room is adequately
lit by natural light.
• Power base (OPB 15) available for line voltage applica-
tions
• Ultrasonic (U/S) Components: One or two U/S trans-
ducers and one or two narrow bandwidth receivers
each 16mm in diameter. Frequency -- Crystal con-
trolled to ±.005%.
• Device: Rug ged, high-im pact, in jec tion molded plas-
tic, off -white. Col or coded leads 6” (16.24 cm).
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 Adaptive Reaction
If motion is sensed within a short period after
the lights go o, then the current delayed
o-time setting is increased.
