OSF10
DESCRIPTION
Leviton’s OSF10, Integral Occupancy Sensor, is designed to be
mounted directly into a luminaire. The OSF10 offers a sensor and
relay in one device. The wiring and housing of the sensor is installed
adjacent to the ballast and hidden from view behind the reflector
cover. Only the PIR detector dome lens and locking ring are visible on
the exterior of the fixture.
APPLICATIONS
Leviton’s Integral Fixture Mount Occupancy Sensor is designed
specifically for pre-wiring and installing inside of luminaire fixtures.
• Small offices
• Cubicles
• Task lighting
• Cabinet lighting
• Small bathroom lighting
FEATURES AND BENEFITS
• Easy installation with longer 38” leads allows for easy connection
to any ballast and eliminates the need to splice additional wiring
• Passive infrared detection technology for accurate sensing
• True Zero-Cross relay technology provides maximum contact
life and compatibility with electronic ballasts
• Adjustable Time Delay located on sensor housing for easy access
• Aesthetically pleasing design
• Compact size for tight spaces
• 8’ mounting heights for indoor use
• Internal fixture mount reduces number of devices on ceiling

OPERATION
The OSF10 utilizes passive infrared (PIR) technology
with Auto-ON/Auto-OFF operation and an adjustable
Time Delay to detect motion within its field of
view. A small semiconductor heat detector resides
behind a multi-zone optical lens, making the sensor
sensitive to the heat emitted by occupants.
This Fresnel lens establishes dozens of zones of
detection. In order to initially trigger the sensor,
the source of heat must move from one zone of
detection to another. The OSF10 is most effective in
sensing motion across its field-of-view.
Once the device senses motion, the sensor will
automatically turn the lights ON. When motion is
no longer detected, the sensor will conclude that
the space is unoccupied. This will initiate the Delay
Timer. If the delay timer expires and no motion
is detected, the lights will turn OFF. If motion is
detected, the delay timer will stop and the lights will
remain ON.
INSTALLATION
The OSF10 is designed to mount directly into a
light fixture, with only the PIR lens being visible.
The wiring and housing of the sensor is installed
adjacent to the ballast, hidden from view behind the
reflector’s cover.
