PRODUCT DATA
ODC Series Ultrasonic Occupancy Sensors
FEATURES
• Robust and reliable mechanically held 10A 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
• Visual LED indicators for all states:
• Green - Blinks during U/S detection and is 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 - con-
sult 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
• Meets Energy Star® Requirements for multi-tech
and ultrasonics
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 natural light or
electric sources in the space
• Open loop: Photocell detects daylight or
electric light only; requires manual calibration
• Adjustable daylight design levels: Normal (OFF),
Manual (ON/OFF) and Auto Calibration
• Integrated photocell tested to less than 1 Fc
accuracy
• Open and closed loop photocell included
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
