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.
The sensor's receiver identifies any change in frequency
as motion and either turns the lights on or maintains
lights on.
appLicationS
• Cafeterias • Classrooms
• Filing rooms • Open areas
• 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.
• Hallways
• Ambient Light Recognition: A Light Sensor prevents
• Restrooms
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).
Adaptive Reaction
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.
If motion is sensed within a short period after
the lights go o , then the current delayed
o -time setting is increased.
