WARNINGS AND CAUTIONS:
• To be installed and/or used in accordance with appropriate electrical codes and regulations.
• If you are unsure about any part of these instructions, consult a qualified electrician.

• Sensor can be ganged together with other units in a multiple-switch
wall plate.
• Self-Adaptive Technology adjusts to occupancy patterns of use in auto
adapt mode.
• The Adapting Time-out walk-through feature prevents lights from
remaining ON for an extended period after only a momentary
occupancy.
• Switches two separate load circuits.
• Two (MD and GD models) convenient Push-Buttons provide manual
ON/OFF switching at any time.
• Adjustable horizontal field of view.
• Integrated photocell prevents lights from turning ON when room is
adequately illuminated by natural light.

DeSCRIpTION
Leviton's Designer Multi-Technology Wall Switch Occupancy Sensor,
Cat. No. OSSMD, is designed to detect motion using the passive infrared
(PIR) sensor from sources (such as a person entering a room) within its
field-of-view (monitored space) and automatically switch lights ON. The
Occupancy Sensor senses motion within its maximum coverage area of
2400 sq. ft (223 m 2 ). The Ultrasonic (US) sensors work with the PIR to
keep the lights ON when occupied. The controlled lights will remain ON
until no motion is detected and the scheduled time-delay has expired, at
which point the lights will be turned OFF. In adapting time-out mode the
sensor adapts its time delay settings to the occupancy patterns of a room.
The OSSMD-MD is an Occupancy Sensor that is designed to control two
separate lighting control circuits from a single unit. This allows the user to
replace two switches with a single unit that will provide the convenience
and energy savings of an occupancy sensor. It is a dual relay device,
relay one can be Auto ON or Manual ON and relay two is Manual ON
only. The device contains a photocell that provides an Ambient Light Hold
Off function for relay number one. Both relays operate as Auto OFF. The
device can be configured for either Ultrasonic with PIR or Ultrasonic Only
modes of operation.
The OSSMD-GD has all the functionality of the OSSMD-MD without a
neutral conductor. It is intended for use in retrofit applications where a
neutral is not available in the wall box.
The OSSMD-FT model is intended for applications such as a commercial
bathroom where a convenience exhaust fan must be controlled. The
two relays turn ON in tandem but remain ON for different durations.
The device can be configured to be either in the Auto ON or Manual
ON modes. The Auto ON mode utilizes the sensor technology to turn
ON while the single push button on the front of the device provides the
Manual ON activation. A fixed time delay OFF of 10 minutes, which starts
when the first relay turns off, will apply to the second relay in both of these
modes of operation. It can be configured for either Ultrasonic with PIR
or Ultrasonic Only modes of operation. This device requires a neutral
conductor.
Cat. No. OSSMD is eTL listed, ceTL listed and conforms to California
Title 24 requirements.
The PIR Occupancy Sensor uses a small semiconductor heat detector
that resides behind a multi-zone optical lens. This Fresnel lens
establishes dozens of zones of detection. The Sensor is sensitive to the
heat emitted by the human body. In order to initially trigger the Sensor,
Multi-Technology Designer Wall Switch Occupancy Sensor with Dual Relays
Incandescent/Tungsten: 800W @ 120V Primary/Secondary
Ballast: 2700VA @ 277V Primary - 1200VA @ 277V Secondary
Compatible with incandescent lamps, low-voltage lighting with electronic and magnetic transformers, electronic and magnetic fluorescent ballasts, and fans.
the source of heat must move from one zone of detection to another. The
device is most effective in sensing motion across its field-of-view and it is
less effective sensing motion towards or away from its field-of-view. Keep
this in mind when selecting the installation location (refer to Field-of-View
diagrams).
The US Occupancy Sensor uses a non-audible, high frequency (40kHz)
to sense Doppler shifts caused by motion in the space. The US is more
sensitive to small motion and does not rely on line of sight for detection. If
both sensors have not detected any motion for the set timeout period, the
relays and their corresponding loads will be turned OFF.
Note that occupancy sensors respond to rapid changes in temperature, so
care should be taken not to mount the device near a climate control source
(i.e. radiators, air exchanges, and air conditioners). Hot or cold drafts will
look like body motion to the device and will trigger it if the unit is mounted too
close. It is recommended to mount the Occupancy Sensor at least 6 feet
away from a climate control source.
In addition, it is also recommended NOT to mount the Occupancy Sensor
directly under a large light source. Large wattage bulbs (greater than
100W incandescent) give off a lot of heat and switching the bulb causes a
temperature change that can be detected by the device.
Mount the Occupancy Sensor at least 6 ft. away from large bulbs. If it is
necessary to mount the device closer, lower the wattage of the bulb directly
overhead.

OSSMD-GD Wiring Methods
NOTe: The occupancy sensor Cat. No. OSSMD-GD does not require a
neutral connection in order to operate. It must have a ground connection.
Use the ground wire in the electrical box for ground connection. If there is
no ground wire, ensure electrical box is grounded and attach ground wire
to box by an approved connection method.
