Leviton PIR Ceiling Occupancy Sensor 120–277V

Leviton ODC0S-I1W is a self-contained ceiling-mounted PIR occupancy sensor that automatically switches lighting on and off for commercial small spaces without a separate control pack. The ODC0S-I1W combines motion sensing, a built-in switching relay, and ambient-light detection in a compact white enclosure designed for retrofit or new installations where a recessed fixture or external control module is impractical. Rated for 120–277V and up to 1000W incandescent/1000VA fluorescent, this sensor covers roughly 530–570 square feet from an 8-foot ceiling and includes adjustable time-out and daylight thresholds for energy-conscious lighting control.

How does the sensor detect people and avoid false triggers?

The unit uses passive infrared (PIR) technology with a segmented Fresnel lens that divides the ceiling view into detection zones. When infrared energy shifts across those zones, the sensor registers motion and turns lights on. It’s optimized for small rooms and corridors where cross-zone movement is common.

• Passive infrared detection with segmented Fresnel lens for reliable motion sensing
• 360-degree coverage when ceiling-mounted for broad zone monitoring
• LED indicator confirms motion detection and proper wiring

What installation and electrical specs should an electrician expect?

The ODC0S-I1W is self-contained, meaning the switching relay and sensor are inside one housing—no external power pack required. It’s compatible with standard 120–277VAC circuits and supports up to a 1000W incandescent or 1000VA fluorescent load, simplifying wiring in retrofit and new commercial jobs.

• Self-contained sensor and relay—reduces labor and material needs
• 120–277VAC operation, 60Hz, 1000W incandescent / 1000VA fluorescent rating
• Compact footprint (about 4.3 in. diameter × 2.15 in. depth) for ceiling mounting

How can I adjust settings for energy savings and daylight?

The sensor provides a user-adjustable time delay from about 20 seconds up to 15 minutes to match traffic patterns and avoid premature shutoff. It also includes an ambient-light override (daylight threshold) that can be set roughly between 0.5 to 500+ foot-candles so lights won’t turn on when natural light is sufficient.

• Delayed OFF time: adjustable 20 seconds to 15 minutes
• Ambient-light override prevents unnecessary switching in daylight
• Toggle override option to force lights OFF during presentations

Is the sensor compliant with codes and backed by warranty?

The ODC0S-I1W is UL listed and CSA certified, meeting common electrical and safety standards used in commercial projects. It complies with California Title 24 energy requirements and carries a five-year limited warranty for added confidence in long-term installations.

• UL and CSA certifications and FCC compliance
• Title 24 compatible for energy-code installations
• Five-year limited manufacturer warranty

Who is this for This Leviton ceiling-mount occupancy sensor is aimed at contractors, facility managers, and building owners who need a compact, easy-to-install motion control for storage rooms, small bathrooms, copy rooms, closets, and other small commercial spaces without wall switches. It’s particularly useful for retrofit projects where installing recessed units or external control packs would add cost or complexity, offering straightforward energy savings and reliable automated lighting control.
