Occupancy Sensor
Infrared Ceiling Sensor
OSC04-IOW
OSC15-IOW
The all-digital & microprocessor based OSCxx-I
is the most advanced infrared ceiling sensor
available. Self-calibrating sensitivity and timer
allow the installer to “install & forget.”
THE OSCXX-I OCCUPANCY DETECTOR
• PASSIVE INFRARED TECHNOLOGY (PIR)
• SIMPLE, FAST INSTALLATION
• SELF-ADJUSTING
• DIGITAL TECHNOLOGY, COMPLETE RELIABILITY
• PHOTOCELL CONTROL
• IMMUNITY TO AIR CURRENTS
GENERAL OPERATION
The OSCxx-IOW Infrared Ceiling Sensor is a low voltage occupancy
detector that works in conjunction with the Leviton OSPxx power
pack to control lighting. The detector’s main function is to turn the
lights on or maintain the lights on while movement is detected
within the sensor’s range and to turn the lights off when the space
is left unoccupied.
The sensor uses a small semiconductor heat detector that resides
behind a multi-zone optical lens. This Fresnel lens establishes
dozens of zones of detection. The sensor is sensitive to the heat
emitted by the human body. In order to trigger the sensor, the
source of heat must move from one zone of sensing to another.
Non-moving hot objects will not cause the lights to turn on.
HOW THE ODC04-I AUTOMATICALLY ADAPTS
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.
A dedicated internal microprocessor continually analyzes
the room environment and adjusts itself automatically.
The internal timer and infrared sensitivity are automatically
adjusted. Once installed, the OSCxx does not require
manual adjustment or calibration.
At a distance close to the sensor,
slight movement can be sensed.
As the distance away from the sensed
increases, the space between the
zones of sensitivity increases, and
therefore the amount of motion
required to trigger the sensor
increases.

FEATURES
Small Size: Installed sensor appears almost invisible.
Fast, Simple Installation: Easy ceiling mount, three wire connection
(low voltage) and twist-lock sensor attachment.
Self-Adapting: An internal microprocessor continually analyzes, evaluates
and adjusts settings. Performance is kept at a maximum and user
complaints are eliminated.
Maximum Reliability, Low Cost: All digital circuitry uses a minimum of
components.
Timer Setting: Automatic - 30s to 30 min. Manual and Automatic.
Test mode - 6 sec.
Ambient Light Recognition: A photocell prevents lights from turning on
when the room is adequately lit by natural light.
Non-Volatile Memory: Learned and adjusted settings saved in protected
memory are not lost during power outages.
