DESCRIPTION
The Leviton O2C Dual Relay Occupancy sensors
combines line voltage occupancy sensors
and photocells into a self-contained unit. The
integrated design alleviates the need for separate
power pack and occupancy sensor wiring making
it a low-cost, efficient energy solution for new
construction and retrofits. For true Daylight
Harvesting applications, an integrated photocell
provides consistent Daylight Design Levels by
actively switching the connected load(s) ON
and OFF in response to available natural light
to maximize energy savings. Vacancy timers
continually analyze and adjust to changing
conditions using the latest microprocessor-based
technology to optimize performance. Auto ON/
Auto OFF automatically turns lights ON and
keeps them ON when occupancy is detected and
automatically turns lights OFF when the space
is vacant or unoccupied. Wire terminals allow for
simple connection to a line-voltage circuit and are
ideal for existing buildings with limited access to
wiring and new construction.

FEATURES
• Sensors combine both PIR and U/S technol-
ogy for unrivaled performance and reliability
• Sensors use PIR technology to initially turn
lights ON, and use U/S technology to keep
the lights ON
• Exclusive false-detection software assures
lights are ON only when needed
• Auto temperature – adjusts tech sensitivity
for optimal detection/operation
• Auto-Adapting: Time delay and sensitivity
are continually adjusted to occupancy
pattern of use
• Vacancy Sensing Time Outs
- Delayed OFF Timer
- Exclusive Walk-through Feature
• False Detection Timer: (M/T) PIR scans for
movement and shuts lights off after 31
minutes without movement, preventing false
triggers from HVAC systems
- Time delay and saved settings are protected
during power outages and will return to the
last known state
• Output short circuit protection
• Industry-exclusive self-configuring local
manual switch input: Momentary or
maintained switches are supported
• Presentation Mode allows user to turn lights
OFF and keep them OFF while the room is
occupied
• Adjustable Time Delay: 30s, 5min, 10min,
20min, 30min
• Test Mode for simplified commissioning
• Manual Switch and Emergency Override are
Class 1 and Class 2 circuits. Class 2 circuits
provided for flexibility
• Industry-exclusive “fail-safe” circuitry: In the
event of product failure, Return-to-Closed
feature causes the relay to default ON which
eliminates life safety concerns

FEATURES
• Industry-exclusive H.I.S. (High Inrush Stability)
technology designed to handle today’s high inrush
electronic ballast loads and offer unmatched durability
and service
• Robust and reliable mechanically held latching
relay provides dependability and robust performance
for all load types and provides energy savings over
electronically held relays
• Field of View: Units from 500 to 2000 square feet
available
• Lenses are easily replaceable and color-coded red
(mid-range), black (extended range) and blue (high
denisty) for contractors and end-users to easily identify lenses from the ground
• Visual LED indicators for all states:
- Red - Blinks when infrared is detecting motion and
during photocell manual calibration; solid during
device malfunction
- Green - Blinks when U/S is detected; solid during
auto calibration
- Yellow - Blinks during test mode; solid with
emergency/BMS input
- Blue - Blinks when knob settings are changed and
during photocell override
RATINGS AND TESTING
• Zero-crossing circuitry for extended life of the relay
• Tested to exceed 1 million switching cycles under
standard loads
• Multiple compliance and regulatory UL testing -
consult factory for details
• Passed rigorous NEMA 410 testing for electronic ballast
rating
• BMS Input/Emergency Override: UL 924 listed for
Emergency and Egress lighting control
Photocell Features
• Daylight Harvesting Applications:
• Auto-Calibration (Automatic Daylight
Calibration): Photocell intelligently measures
light levels to determine optimal daylight
design levels for closed loop applications
- Closed loop: Photocell detects total
photometric light from daylight or electric
sources in the space
- Open loop: Photocell detects measurement
of natural light only (sunlight from window or
skylight)
• Adjustable daylight design levels: Normal (OFF),
Manual (ON/OFF) and Auto Calibration
• Integrated photocell tested to less than 1 Fc
accuracy
INSTALLATION
• Easy installation into junction boxes with Leviton-
exclusive screw guides, coasters and terminal
blocks
• Front cover snaps on and off for ease of
installation
