Occupancy Sensor, Multi-Technology (PIR Sensor / Ultrasonic Sensor), Wall Switch, Dual Relay, 2400SF, 120-277V, No Neutral, Black, Decora®


Dual relay multi-tech wall box occupancy sensor w/no neutral wire lighting control, 120/208/220/230/240/277v, 50/60Hz, CEC Title 20/24 Compliant, 30s-30m Time Delay, Ambient Light Override, Self Adjusting, Field Configurable, USMCA Compliant. Color: Black

The OSSMD provides automatic lighting control for two separate loads from a single unit. It is compatible with incandescent, fluorescent, low-voltage lighting, and fan loads. The unit features dual manual-override switches that can be used to toggle the ON/OFF status of each lighting load while an area is occupied. The OSSMD can be installed in place of two single-pole wall switches and fits in a standard single-gang wall box.

  • Provides automatic lighting control for two separate banks of fluorescent, incandescent, or low-voltage lighting from a single unit.
  • The second relay is a manual-ON only with a maximum 30 minute time-out for maximum energy savings to comply with CEC Title 24.
  • Fits in a standard single-gang wall box and replaces two single-pole wall-switches for fast and easy installation; neutral and ground connection required for OSSMD-MD. OSSMD-GD does not require a neutral for installation.
  • Low-profile design eliminates obtrusive “scanning-device” look. Elegant Decora wallplates complement any interior for sleek aesthetics; uses Decora wallplates and coordinates with Leviton’s popular line of Decora wiring devices.
  • 180° field-of-view provides approximately 2400 square feet of coverage, suitable for a variety of commercial areas.
  • Convenient pushbuttons provide manual-ON/OFF light switching of each load at any time.
  • Segmented Fresnel lens provides optimum sensitivity and performance. Designed with an extensive “minor motion” area where even slight body movements will be detected.
  • Vandal resistant PIR lens.
  • Adjustable horizontal field-of-view (PIR) may be adjusted between 180° and 60° of arc by using integral blinders located on either side of the lens. No masking tape required.
  • Manual-ON/auto-OFF mode for installations where manual-ON switching is required but auto-OFF switching is still desired for CEC Title 24 energy savings.
  • To comply with CEC Title 24, LED indicator light flashes when sensor detects motion to verify detection is active. Green flashes for ultrasonic, red flashes for PIR.
  • Time delay adjustment for delayed-OFF time settings of 30 seconds (for walking test), 10 minutes, 20 minutes, and 30 minutes. Allows customized adjustments to maximize energy savings.
  • Light sensor measures the ambient light in the room when it first detects motion and leaves the lights OFF (hold-off) if there is enough light in the room or turns the lights connected to the first relay ON if there is not enough light in the room.
  • Self-Adaptive technology eliminates callbacks for adjustments. Time delay and sensitivity settings are continually adjusted to occupant patterns of use in auto adapt mode.
  • Exclusive Walk-Through feature provides increased energy savings by not leaving the lights ON for an extended period after only momentary occupancy.
  • Non-Adaptive Mode disables self-adjusting delayed-OFF time and walk-through feature in applica-tions where these feature are not desired. Optional manual adjustment for delayed-OFF time settings allows customized adjustments to maximize energy savings.
  • Vacancy confirmation; when the time out expires and the relay turns OFF, a 30-second vacancy confirmation exists to turn the relays back ON.
  • False detection circuitry.
  • U/S technology provides excellent minor motion sensitivity.
  • Ability to disable PIR or U/S for added flexibility.
  • Presentation Mode feature for slide or film presentations allows pushbuttons to turn lights OFF and keep them OFF while the room is occupied.
  • Exclusive Leviton High Inrush Stability (H.I.S.) Circuitry. Specifically designed to handle today’s high inrush electronic ballast loads and offer unmatched durability and service.
  • One unit can be used for 120V through 277V lighting. Compatible with both electronic and magnetic ballasts.
  • True zero-cross relay switches at the zero crossing point of the AC power curve to ensure maximum contactor life and compatibility with electronic ballasts.
