OPERATION
PUSH-BUTTON: Cat. No. OSSMT-MDx has a push-button switch
that will toggle the lights (refer to Figure). If the lights are OFF, the
lights will turn ON when the 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 lights OFF.
If the lights are ON, the lights will turn OFF when the button is pressed.
The lights will stay OFF regardless of motion detected, until the Time-
Out expires. After the Time-Out expires, the lights will turn ON with the
next detected motion. This is useful for slide or film presentations.
NOTES:
• The Motion Indicator LED will blink every 2 seconds while motion is
detected.
• 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.

TROUBLESHOOTING
1. If there is no response from the unit and the LED never blinks or the
push button does not activate the lights 1 1/2 minutes after power is
applied, then uninstall device and verify wiring (Step 4).
2. If the lights constantly stay ON, even when the room is unoccupied:
A. Check the Time setting. See how this time compares to how
long the lights stay ON.
B. Try lowering the Range Control. Rotate the knob counter-
clockwise about 30˚.
C. If the problem persists, try reducing again. Note: Do Not reduce
so much that Cat. No. OSSMT-M
Dx cannot see normal
occupancy.
D. Be sure to use the Blinders to block any unwanted hallway
traffic.
E. Check for reflected heat/motion as Sensor Unit may be seeing
motion through a window.
F. Check for adjacent HVAC and/or heater ducts.

SETTINGS
NOTE: 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-M
Dx. Use a small straight blade
screwdriver to adjust the knobs and your finger to adjust the blinder
levers.
1. Remove Decora
®
wallplate 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-clock-wise (CCW).
4. Set the Ambient Light Level - AMBIENT LIGHT: Cat. No.
OSSMT-M
Ø
x 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.
NOTES:
• If Manual-On mode is desired, turn the Lights knob to fully
counter-clockwise (CCW) position.
A. With the lights ON, rotate the Time Control fully CCW to the set
the Time-Out to the thirty (30) second test mode (refer to
Control Panel Diagram)
.
B. Rotate the Light Control fully CCW.
C. Cover the Sensor Unit with an opaque material, or leave the
room and let the Sensor Unit Time-Out and turn the lights
OFF.
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.
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.
6. Time-Out Settings:
A. Adjust the Time dial. The Sensor 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. Be sure the Time dial is rotated until an Amber
LED flash is issued to be sure a new time value was selected.
Then return the Time dial to the desired Time-Out setting.
7. If desired, adjust the blinders to block any unwanted motion.
8. Replace the Control Panel Cover and Decora
®
wallplate.

Step 6 cont’d
If the Sensor detects motion within 45 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 adapted Time-Out may be reset to the base value by rotating
the Time Control to a new time selection value (refer to Control
Panel Diagram
).
Time Control Setting: 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.
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 (lights always turn ON) (see following section). All other
settings will cause the lights to turn ON only when the light level is
less than the setting.
To prevent false low light levels from the user standing in front of
the device during adjustment, the Sensor remembers the ambient
light level from 1 minute ago.
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. 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.
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%.
ULTRASOUND (US) SENSITIVIY:
US sensitivity can be adjusted
to LOW-MEDUIM-HIGH by holding the ON button for 15 seconds.
The Amber LED will flash 3 times (per second) for HIGH, 2 times
for MEDIUM, and 1 time for LOW. Tapping the ON button during
the desired LED flash indication will set the sensitivity. The program
times out in 30 seconds from the last button press. The factory
setting for the US sensitivity is HIGH.
