INSTALLING YOUR SENSOR Tools needed to install your Sensor: Slotted/Phillips Screwdriver Pencil Electrical Tape Cutters Pliers Ruler DESCRIPTION Leviton's Designer Multi-Technology Wall Switch Occupancy Sensor, Cat. No. OSSMT-MDx, 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 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. The sensor adapts its time delay settings to the occupancy patterns of a room. NOTE: Use check boxes 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, 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 lights 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 ft. away from the climate control source. The device can be mounted in a single gang wall box. 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. �� ��� �� �� ��� �� ��� �� ��� �� ��� �� ��� �� ��� �� ��� �� ��� �� ��� �� Step 4 ����� ����� 2 � Preparing and connecting wires: Strip Gage 5/8" (measure bare (1.6 cm) wire here) White White Black Black Load Green Ground White Connect wires per WIRING DIAGRAM as follows: • Green or bare copper wire in wall box to Sensor 1 Green lead. • Line Hot (common) wall box wire identiﬁed (tagged) when removing old switch and First Traveler from Sensor 2 to Sensor 1 Black lead. • Second Traveler wall box wire from Sensor 2 to Sensor 1 Blue lead. • Line Neutral wall box wire to Sensor 1 White lead. � � WIRING SENSOR 2: ����� ����� ����� ���� ���� ������������ ����� ������ ����� Connect wires per WIRING DIAGRAM as follows: • Green or bare copper wire in wall box to Sensor 2 Green lead. • Load wall box wire identiﬁed (tagged) when removing old switch and Second Traveler from Sensor 1 to Sensor 2 Blue lead. • First Traveler Line Hot from Sensor 1 to Sensor 2 Black lead. • Second Traveler wall box wire from Sensor 2 to Sensor 1 Blue lead. • Line Neutral wall box wire to Sensor 1 White lead.

NOTE: Cat. No. OSSMT-MDx is factory preset to work without any adjustments. If necessary, adjust the Blinders and PIR Range Control to stop any unwanted activation of the lights (refer to FEATURES section). • For additional Time Control Settings (refer to the SETTINGS section). Testing your Sensor prior to completely mounting in wall box: NOTE: To avoid PERMANENT DAMAGE to the unit, be careful NOT TO OVERTURN the control knobs or levers when setting the Sensor. The controls can be accessed by removing the wallplate (if applicable) and control panel cover (refer to Control Panel Diagram). Use a small straight blade screwdriver to adjust knobs and blinder levers. NOTE: DO NOT press in on blinder levers or use excessive force (refer to Control Panel Diagram). • Attach the Control Panel cover when the desired settings are complete. If lights do not turn ON, refer to the TROUBLESHOOTING section. FEATURES: NOTE: To access control settings, remove the control panel cover. If necessary, remove the warning label that covers the adjustment dials (refer to Control Panel Diagram). 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, Adapting Time-Out starting with 30 minute Base Time-Out, Lights always turn ON regardless of existing light levels, and Medium range. Blinders: The blinders are two independent shutters that can narrow the ﬁeld-of-view from a maximum of 180° down to 32°. 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: Walkthrough, Fixed, and Adapting. • Walk-through Time-Out: The value of this Time-Out is preset to 2.5 minutes. • Fixed Time-Out: The value of this Time-Out is user selected through the use of the Time Control Setting. • 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: The walk-through feature 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. If the person stays in the room for longer than 2.5 minutes, the Sensor will instead use the time-out per the Time Control setting (refer to Time Control setting in the following sections). 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” motions (as in a person walking by), it will NOT change the Time-Out duration. If the Sensor detects “small”, infrequent motion (as in a person sitting down and writing) it will INCREASE the Adapting Time-Out duration. If the Sensor detects “small”, 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 TimeOut once it has increased it for any of the occupancy conditions sensed). If the room is occupied for longer than 2.5 minutes, the Sensor will enter the Occupied Mode with the time-out duration speciﬁed by the Time Control setting. This time-out is used as the starting point for adapting. After seven days, the Time-Out value will adapt to the “best” value based on the occupancy conditions detected in the room.

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-MØx 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: 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. Face Marking (/) Slash Mark 1 2 3 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. Value of Time 30 second ﬁxed time-out for performing a walk test 10 minutes ﬁxed time-out 20 minutes ﬁxed time-out 30 minutes ﬁxed time-out 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.
