• Learned and adjusted settings saved in protected memory.
• Select the approximate area needed. Units from 500 to 2000 sq. ft. available.
• Accurate, consistent sw: occupant complaints are eliminated; lights are on when room is occupied, off when empty. Annoying false-offs are minimized and lights on at night is eliminated..
• Ambient light re: the photocell prevents lights from turning on when room is adequately lit by natural light..
• Fast simple installation: easy ceiling , three wire connection (low voltage) and twist-lock sensor attachment.
• Maximum reliability, low cost: all digital circuitry uses a minimum of components..

Product Description ------------------- MOTION DETECTOR, SELF-ADJUSTING TYPE; 4.2 INCH DIA X 1.57 INCH D SIZE; OFF-WHITE FINISH; UL, CUL, CSA, FCC, NOM APPROVAL .com ---- Light Your Space the Smart Way ------------------------------ Leviton’s ceiling occupancy sensor offers users a smart way to save energy in larger spaces, up to 2,000 square feet in area. Using both passive infrared (PIR) and ultrasonic (U/S) detection technologies, the OSC20-M0W occupancy sensor is perfect for commercial applications such as cafeterias, classrooms, warehouses, offices with cubicles and more. Leviton’s ceiling occupancy sensors require a Leviton OSP-series power pack, which is sold separately. Save Energy with Multi-Technology Sensors ----------------------------------------- The Leviton ceiling occupancy sensor utilizes a complementary mix of passive infrared and ultrasonic protection to provide the best detection of new motion in a room as well as small motions of occupants already in the room. Passive infrared technology is ideal for initially turning lights on upon the detection of new motion in a room. Ultrasonic technology offers greater sensitivity, utilizing continuous reflective high frequency waves, optimal for keeping lights on in an occupied room. Leviton’s sensor uses multiple technologies to combine the benefits of both PIR and U/S for unsurpassed performance and dependability. Advanced Features for Optimal Performance ----------------------------------------- Leviton’s OSC20-M0W occupancy sensor utilizes advanced technology to provide the best performance and optimized energy savings, as well as substantial customizability. The occupancy sensor features ambient light re, an internal light sensor that prevents electric lights from turning on when the room is lit by natural light, for further energy savings. An internal timer can be set to automatic, 30 seconds, or 30 minutes. An internal microprocessor within the occupancy sensor constantly analyzes, adjusts, and evaluates the sensitivity and time delay of the sensor, ensuring the best performance for each room it is installed in. Both manual settings and learned adjustments are safe and will not be lost, even in the event of a power outage. To save additional power, the sensor has a walk-through setting that decreases the time delay to two-and-a-half minutes when someone momentarily walks through an area. Easy Installation, Wide Compliance, and Leviton Quality ------------------------------------------------------- With only three low-voltage wire connections necessary and a twist-lock sensor attachment, the OSC-20 occupancy sensory is easy to install. The sensor is cUL/US-certified and is compliant with both the California Title 24 Energy Code and the ASHRAE Standard 90.1 requirements. Backed by more than a century of Leviton quality, the OSC-20 is supported by a five-year limited warranty. What's in the Box? ------------------ One Leviton OSC20-M0W ceiling occupancy sensor and manual. At a Glance: ------------ * Automatic lighting control with 360-degree coverage for up to 2,000 square feet. * Save energy by ensuring lights are turned on only when rooms are occupied. * Ambient light override saves additional energy by keeping lights off when sufficient natural light is available. * Works in conjunction with the Leviton OSP-series power packs. * Flexible timing options.
