Leviton's Designer Multi-Technology Wall Switch Occupancy Sensor,
Cat. No. OSSMT, 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) to automatically
switch lights ON. The Occupancy Sensor senses motion within its
maximum coverage area of 2400 sq. ft (223 m2). 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 OSSMT is an Occupancy Sensor that is designed to control a
single lighting control circuit and provide the energy savings of an
occupancy sensor.
The OSSMT is a single relay device, which can be Auto-ON or
Manual-ON. The device contains a photocell that provides an Ambient
Light Hold-Off function. The device is configurable for either Ultrasonic
with PIR, or Ultrasonic-Only modes of operation.
Cat. No. OSSMT-M3 is cETL listed and conforms to California
Title 24 requirements.
The PIR Occupancy Sensor uses a small semi-conductor 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,
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 at 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 Time-Out period,
the relay and its corresponding load 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 (e.g., 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.
WARNING: TO AVOID FIRE, SHOCK, OR DEATH, TURN
OFF POWER at circuit breaker or fuse, and test that power
is off before wiring!

Testing Your Sensor Prior to Completely
Mounting in Wall Box:
Step 6
NOTE: To access Control settings, remove the Control Panel cover.
Factory Settings: The sensor is shipped from the factory to work in
almost all situations, without any added adjustments. The factory settings
are: Blinders open, 10 minutes fixed Time-Out, Lights always turn ON
regardless of existing light levels, Medium Passive Infrared (PIR) range,
and Medium Ultrasonic range. The PIR and Ultrasonic technologies are
both active.
Blinders: The Blinders are two independent shutters that can narrow the
field-of-view from a maximum of 180°, down to medium. The Blinders are
operated by moving the Blinder levers towards or away from the center
of the Sensor. The Blinder levers can be found above the control dials in
the Control Panel (refer to Control Panel Diagram).
Time-Outs: The Sensor has three types of Time-Outs: Fixed, Adapting,
and Walk-Through.
• Fixed Time-Out: The value of this Time-Out is user-selected,
through the use of the Time Control setting (refer to Control Panel
Diagram and Time-Out settings).
• Adapting Time-Out: When activated, the value of this Time-Out
(30 minutes) is changed by the Sensor, based on room occupancy
and lighting conditions.
• Walk-Through Time-Out: The value of this Time-Out is preset to
2.5 minutes, and only exists in the Adapting Time-Out mode.

Fixed Time-Delay: The fixed Time-Out value is selected by rotating
the Time Control dial. There are four (4) values from which to choose.
Each mark around the dial corresponds to a different value, as indicated
below (refer to Control Panel Diagram).
NOTE: All time durations are approximate, within ±10 seconds.
Adapting Time-Delay: The Sensor has built-in adapting intelligence
that changes the Adapting Time-Out duration, in response to the
occupancy conditions of the room it is installed in. If the Sensor detects
“large,” infrequent motion, it will INCREASE the Adapting Time-Out
duration. If the Sensor detects “large,” frequent motion (as in several
persons in a room during a meeting), it will DECREASE the Time-Out
duration, only if it was NEVER increased (this is because the built-in
intelligence will always proceed in the direction of “increasing” adapting
Time-Out, once it has increased it for any of the occupancy conditions
sensed). The Adapting Time-Out duration will range from 10 to 30
minutes in time, plus the Walk-Through Time-Delay.
Walk-Through Time-Delay: The Walk-Through feature, which is
only active in the Adapting Time-Out mode, is useful when a room is
momentarily occupied. With this feature, the Sensor will turn the lights
OFF shortly after the person leaves the room. The Walk-Through feature
works in the following manner: When a person enters the room, the
lights will turn ON. If the person leaves the room before the
Walk-Through Time-Out of 2.5 minutes, the Sensor will turn the lights
OFF after 2.5 minutes. If the person stays in the room for longer than
2.5 minutes, the Sensor will instead use the stored Adapting Time-Out
Delay setting.
If the Sensor detects motion within 30 seconds after the lights turn OFF,
it will turn the lights ON and increase the Time-Out value by 1.5 times
the existing value.
The Adapting Time-Out may be reset to the base value of 30 minutes,
by rotating the Time Control to a new time selection value and then back
to the Adapting Time-Out value (refer to Control Panel Diagram).
Ambient Light Override: The Ambient Light Override is used to keep
the lights OFF if there is already enough natural light in the room.
For proper operation, the Ambient Light Override adjustment must be
performed when there is enough natural light (refer to the SETTINGS
section). If the adjustment is made when there is less natural light, the
lights may not turn ON, even though they are needed and will require
manual activation of the push-buttons to turn the lights ON.
NOTE: The Ambient Light level in the center of a room will be
different than the level at the wall where the switch is located.
Ambient Light Dial: The Ambient Light setting is adjusted with the
Ambient Light dial (refer to Control Panel Diagram). Turning the Light
dial fully counter-clockwise (CCW) sets the Sensor to Manual-ON mode
(see following section). If the Light Control is in the fully CW position,
the lights will turn ON whenever motion is detected, even in full daylight.
Intermediate settings will cause the lights to turn ON only when the
ambient light is below the level selected by the Light Control.
NOTE: When the setting is at the minimum CCW level, the lights will
stay OFF when the room is dim. When the setting is at the maximum
level clockwise (CW), the lights will turn ON when the room is bright.
Manual-ON Mode: When the Light Control is in the fully CCW position,
the lights will never automatically turn ON. In this mode, the lights need
to be manually turned ON by the push-button, and will turn OFF with the
absence of motion.
PIR RANGE: To decrease PIR detection range and sensitivity, rotate the
knob CCW (refer to Control Panel Diagram). The detection range can
be adjusted from 100% down to 30%.
ULTRASONIC (US) SENSITIVIY AND PIR DISABLE: US sensitivity
can be adjusted to HIGH-MEDIUM or LOW by holding the ON button
for 15 seconds. The LED will flash to represent the Ultrasonic sensitivity
and PIR status. Tapping the ON button during the desired LED flash
indication will set the Ultrasonic sensitivity and PIR status. Use the
following chart:
Note: To disable/enable Ultrasonic technology:
1 Turn the "light" adjustment knob fully CCW.
2Hold the button down for 6-7 seconds.
3Relase button. Red LED blinking = PIR only.
Green LED blinking =US active.

PUSH BUTTON(S)
Cat. No. OSSMT has a single push-button switch that toggles the relay
and its corresponding load ON and OFF (refer to figure). If the relay is
OFF, the relay will turn ON when the push-button is pressed, and remain
ON in the presence of motion. In the absence of motion, the Sensor Unit
will Time-Out and turn the relay OFF.
NOTES:
• The Motion Indicator LED will blink every second while motion
is detected. A red blink represents PIR detection. A green blink
represents Ultrasonic detection.
• When the Time-Out expires and the relay turns OFF, a 30-second
Vacancy Confirmation exists to turn the relay back ON. After this time,
the device will be placed into a lower detection threshold mode.
• In Manual-ON mode, the button must be pressed to turn the lights ON.
In the absence of motion, the unit will Time-Out and turn the lights OFF.
• If Manual-ON mode is desired, keep the Light knob in the fully
counter-clockwise (CCW) position.
CAUTION: To avoid PERMANENT DAMAGE to the unit, be careful
NOT TO OVERTURN or use excessive force when setting the control
knobs or levers of Cat No. OSSMT. Use a small straight-blade
screwdriver to adjust the knobs, and your finger to adjust the
Blinder levers.
1. Remove Decora®wall plate and Control Panel cover from Sensor.
2. Rotate the Time dial to select the desired fixed Time-Out value.
3. If the Sensor is installed within 6 feet of an air duct, rotate the Range
Control 1/4 turn counter-clockwise (CCW).
4. Set the Ambient Light Level - AMBIENT LIGHT: Cat. No. OSSMT
has an adjustment to determine at what minimum Ambient Light
level the unit will operate. The adjustment should be made when the
ambient light is at the level where no artificial light is needed. Follow
these steps to make a more accurate adjustment of the Light Control.
This feature will not work in Manual-ON mode.
A. With the lights ON, rotate the Time Control fully CCW to set the
Time-Out to the thirty (30) second Test mode (refer to Control
Panel Diagram).
B. Rotate the Light Control fully CCW.
C. Manually turn OFF the lights.
D.
Rotate the Light Control clockwise (CW) SLOWLY, until the lights
turn ON. This is the setting for the current level of light in the room.
Adjust the Light Control back (CCW) a little, so that the lights will not
turn on with the current room lighting level. Leave the room and wait
for the 30-second Time-Out and 30-second Vacancy Confirmation
(45-second confirmation for the OSSMT-M3) to expire. Perform a
walk-through to see if the lights turn ON with the new Ambient Light
level adjustment. Repeat this adjustment as needed, to keep lights
from turning ON under conditions when enough light is present.
NOTE: When the Light Control is in the fully CCW position, the
lights will never automatically turn ON. This is the Manual-On
mode, where the lights need to be manually turned ON by the
push-button, and will turn OFF with the absence of motion.
If the Light Control is in the fully CW position, the lights will turn ON
whenever motion is detected, even in full daylight.
Intermediate settings will cause the lights to turn ON only when the
ambient light is below the level selected by the Light Control.
NOTE: The ambient light in a room will change with the time of day
and the season of the year.
5. Time-Out Settings:
A. Adjust the Time dial. The Sensor's amber LED will flash twice each
time the Time dial is pointed at a new Time-Out value.
The Time-Out values for Non-Adapting mode are:
NOTE: To return to Adapting mode, rotate the Time dial to full CW
position (A setting). Be sure the Time dial is rotated until an amber
LED flash is issued, to be sure a new setting was selected.
