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: The lights must be manually
turned 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).
Manual ON Mode: This Vacancy Sensor only operates in the Manual
ON mode.
Vacancy Confirmation: The OSSMT Vacancy Sensor has a 30
second grace period when the lights turn OFF. If motion is detected
during this 30 second time frame the lights will automatically turn back
ON. This grace period exist in case a false-OFF occurs where the
lights go off in a room while the room is still occupied.
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% (40 ft) down to 30% (10 - 20 ft).
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: Green flashes on OSSMT-GT models only):
LIMITED 5 YEAR WARRANTY AND EXCLUSIONS

proof of purchase date, and a description of the problem to
Leviton Manufacturing Co., Inc., Att: Quality Assurance Department, 201 North Service Road, Melville, New York 11747. This warranty excludes and there is disclaimed liability for labor for removal of this product or reinstallation. This warranty is void if this product is installed improperly or in an improper environment, overloaded, misused, opened,
abused, or altered in any manner, or is not used under normal operating conditions or not in accordance with any labels or instructions.
There are no other or implied warranties of any kind, including merchantability and fitness for a particular purpose, but if any implied warranty is required by the applicable jurisdiction, the duration of any such implied warranty, including merchantability and fitness for
a particular purpose, is limited to five years.
Leviton is not liable for incidental, indirect, special, or consequential damages, including without limitation, damage to, or loss of use of, any equipment, lost sales or profits or delay or failure to perform this warranty obligation. The remedies provided herein are the exclusive remedies under this warranty, whether based on contract, tort or otherwise.
1. If there is no response from the unit and the LED never blinks, then
uninstall device and verify wiring
(Step 4).
2. If the lights are nuisance tripping ON from hallway or other
unwanted locations:
A. Try lowering the PIR Range Control. Rotate the knob
counterclockwise and repeat as needed.
3. If the lights constantly stay ON, even when the room is unoccupied:
A. Try lowering the Ultrasonic Sensitivity.
B. Be sure to use the Blinders to block any unwanted hallway
traffic.
C. Check for reflected radiated heat/motion such as incandescent
bulbs, mirrors, HVAC, swinging fixtures, moving mechanical
parts, flowing hot water within view, overhead doors opening
closing, etc.
D. Check for adjacent HVAC and/or heater ducts.
If your OSSMT has a flashing amber LED, the zero-cross failure
over-ride has occured, but the sensor will still operate until you
are able to reach technical assistance.
4. If the sensor is turning lights OFF (False OFF):
A. Check time delay and extend to 20 or 30 minutes.
B. Check range sensitivity of PIR and U/S and increase.

PUSH BUTTON(S)
Manual ON/Auto OFF: In Manual ON/Auto OFF mode the lights can
only be turned ON manually. In the absence of motion, after the time out
expires, the lights will turn 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.
• The OSSMT Vacancy Sensor has a 30 second grace period when the
lights turn OFF. If motion is detected during this 30 second time frame
the lights will automatically turn back ON. After this time the device will
go back to a Manual ON ONLY device.
