Overview

  • Replaces a regular wall switch and automically turns lights on when someone enters a room
  • Increases energy savings by turning lights off after only momentary occupancy
  • Integrated photocell prevents lights from turning on when the room has adequate natural light
  • Combination of PIR and ultrasonic technology provide excellent motion sensitivity
  • Self-adaptive technology has been designed for "install and forget" use

Essential Info

A standard passive infrared (PIR) occupancy sensor switch is appropriate for use in areas with an unobstructed view of the sensor and where motion coverage is within the sensor's range. For large applications, consider using the Leviton Multi-Tech PIR/Ultrasonic Occupancy Sensor Decora Wall Switch which uses both PIR and Ultrasonic technology. It works well to turn lights ON when a person enters a room and OFF when they leave. The ultrasonic technology is ideal for spaces such as private offices, small open offices, restrooms, hallways, conference and meeting rooms, irregular shaped rooms, rooms with partitions and storage areas where the switch location does not permit direct line-of-sight to the PIR. It also features walk-through sensing that provides increased energy savings by not leaving the lights ON for an extended period after only momentary occupancy. It even analyzes room conditions and adapts to errors or changing environment; resulting in less false reading and greater convenience and energy saving. With a 180° field of view and up to 240 square feet of coverage, a single Multi-Tech switch can do the same job as multiple standard PIR switches. By limiting a switch to operation only when a room is being occupied, you can decrease the amount of energy being consumed on a daily basis.

    Compatibility
    The Leviton Multi-Tech PIR/Ultrasonic Occupancy Sensor Decora Wall Switch is compatible with incandescent lamps, electronic and magnetic low-voltage ballasts, electronic and magnetic ballasts, and fans.

    Enhanced Adjustment Options
  • Blinders: Integral sliding blinders on each side of the lens may be used to restrict the 180° field of view down to 32°. This will prevent unwanted detection in areas such as hallways.
  • Time: The delayed OFF time is preset at 30 minutes in the Auto Adapting mode. A choice of four delayed-OFF time settings is available: 30-seconds (for walking test purposes only), 10, 20, and 30 minutes for fixed time and auto adapting. The LED will flash when the adjusting knob is set to the indicated time value.
  • Range (PIR): Adjusting the range allows the unit to ignore motion at the far end of its range and avoid unnecessarily switching lights ON. The range can be adjusted from 100% to 35% of the total coverage area.
  • Sensitivity (US): Users can adjust internal ultrasonic operation to maximize detection of motion while minimizing the effects of environmental noise (electrical noise, air currents, temperature changes, etc.). Adjustment is made by pushing the ON-OFF button in a prescribed sequence to Low-Medium-High sensitivity
  • Light: The OSSMT is factory preset without any ambient light override in effect. This means the unit will switch lights ON when it detects occupancy, regardless of the amount of natural sunlight present. To maximize energy savings in some installations, the ambient light override feature will prevent the unit from switching lights ON when there is ample natural sunlight, regardless of occupancy. This adjustment should be made when the ambient light is at the level where no artificial light is needed.
  • Push-Button Manual Override Control: For manual control, the there is a convenient push-button switch. If the lights are OFF, pressing the button will turn lights ON and keep them ON for as long as the room is occupied. The lights will be turned OFF once the room is vacant, after the delayed-OFF time expires.
  • Manual-ON/ Auto-OFF Mode: In this mode, the unit will not turn lights ON automatically when motion is detected. Lights can only be turned ON manually by pressing the push-button. The lights will remain ON as long as the unit detects activity in the sensor zones. It will shut lights OFF automatically after the space becomes unoccupied and the delayed-OFF time expires.

    LYLE -- roswell, GA   10/15/2011
    The PIR/Ultrasonic motion sensing works great. Easy to install.
    BRYAN -- sutton, MA   9/8/2010
    EXCELLENT. It worked better (was much more sensitive) than the other less expensive Leviton product I bought from Home Depot. My wife and I are very happy with it.
    ROBERT -- palo alto, CA   2/20/2010
    using it for a pantry hands-free light; switch installed in ceiling. Works well with electronic balast. Arrived in time. Money well spent
