Maestro Sensor
The Maestro dual technology (dual tech) occupancy sensor switch applies
our exclusive XCT Technology to the ultrasonic as well as the passive infrared
technology in this sensor to create a product that can detect very fine
motion, such as typing. This product also includes all of the great features
found in the rest of the Maestro sensor family, including: adaptive relay
switching, smart ambient light detection, and simple button presses for
changing settings. The Maestro dual tech occupancy sensor switch is
available in single-circuit and dual-circuit versions.
The single-circuit versions (MS-A102, MS-B102) can be used to meet many
of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as
“automatic shutoff”. The dual-circuit versions (MS-A202, MS-B202) can be
used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code
requirements such as “automatic shutoff” and “multi-level lighting control”.

Custom Settings - Details
Ambient Light Detection (ALD) mode
Lights turn on only when natural light in the room is
below the set threshold.
Learning: The ambient light threshold adjusts to
the user’s preference via manual interaction with
the sensor switch.
Fixed: Choose a fixed ALD light level from four
pre-set options:
High, Medium, Low, and Minimum
Manual Off-While-Occupied Options
ENABLED (default setting)
When the sensor switch is manually turned off,
the sensor switch will not turn the lights back on
automatically while the room is occupied.
Once the room is vacated, the Auto-On feature
returns to normal operation after the timeout
period has expired.
This may be the preference in conference rooms
or classrooms while viewing presentations. This
feature requires motions to keep the lights off.
DISABLED
When the sensor switch is manually turned off,
the Auto-On feature will return to normal operation
after 25 seconds.
This may be the preference in a restroom if the
user always wants the lights to turn on upon
entering and the lights to turn off when the room
is vacant.
Walk-Thru Mode
ENABLED
1
If motion is not detected within 3 minutes after
initial occupancy, the lights will turn off after
3 minutes, instead of the current timeout.
This setting may be the preference in commercial
applications where personnel may briefly trigger
sensors during non-working hours.
DISABLED
(default setting)
When motion is detected, the lights will ALWAYS
remain on for the entire timeout duration,
regardless of the duration of occupancy detection.
1
1 minute timeout would be overridden if walk-thru mode is also ENABLED

When controlling light and fan loads simultaneously on a single-circuit, maximum load capacity per circuit is 4.4 A at 120 V~.
• Ground or neutral is required for product to function. If neither wire is present, consult a licensed electrician.
• For models MS-A102 and MS-A202, connect green-sleeved wire to ground only in retrofit and replacement
applications. When neutral connection is available, remove green sleeve and connect the white wire to neutral.
Sensor switch placement
• The sensor switch performs better with an unobstructed view of room occupants.
• Hot objects and moving air currents can affect the performance of the sensor switch. The sensor switch performs
best when located 6 ft (1.8 m) or more away from hot objects or moving air currents.
• The PIR performance depends on a temperature differential between the ambient room temperature and that of
room occupants. Warmer rooms may reduce the ability of the sensor switch to detect occupants.
• The ultrasonic performance can be affected by air currents and moving objects. Consider the effects of fans,
HVAC vents, open windows, or moving objects when installing the sensor switch.
If the sensor sees a specific area that is not desired (e.g., hallway), Lutron offers a lens mask kit (Lutron P/N
50013614) that can be ordered through Customer Support (1.844.LUTRON1). Alternatively, selectively placing
opaque tape (e.g., painter’s tape, electrical tape, masking tape) over certain parts of the lens can limit it’s field of
vision to block undesired detection areas. Masking the lens may effect ALD performance, but DOES NOT block
ultrasonic frequencies.
Definitions
Major motion: movement of a person entering or passing through an area.
Minor motion: movement of a person occupying an area and engaging in small activities (e.g., reaching for a
telephone, turning the pages of a book, opening a file folder, picking up a coffee cup).
Fine Motion: movement of a person occupying an area and engaging in very small activities (e.g., reading
a magazine).
Very Fine Motion: movement of a person occupying an area and engaging in very small activities (e.g., typing on
a keyboard).

3-way installation
For retrofit 3-way installations the mechanical switch needs to be rewired as shown in the diagram below after wiring the dual
tech sensor switch. Otherwise the 3-way installation will not work as expected. Single pole mechanical switches may also be
used in a 3-way installation with MS-B102, MS-B102-V and MS-B202 models.
Wiring Diagrams - Single-Circuit (continued)
White
1. Connect Ground: Ensure the bare copper or green ground wire from the wallbox is connected to the green ground screw of
the mechanical switch.
2. Tag circuit Common: Your 3-way mechanical switch should have three screw terminals, two of the same color, and one of a
different color. Tag the wire that is connected to the screw terminal of a different color.
3. Identify the wire that matches the color of the wire you connected to the blue wire of the Maestro dual technology occupancy
sensor switch. Connect this wire to one of the two terminals of the same color.
4. Combine the tagged wire, the remaining wire and yellow jumper wire (included) using a wire connector. Connect the other end
of jumper wire to the different color screw.
Note: Dual tech sensor switch can be installed in
any location. However, optimum
performance of sensor may depend upon
installation location, see sensor switch
placement guidelines on page 4.

Mechanical switch may be wired to either circuit, and will control both. Do NOT wire mechanical switch to both circuits.
3
You may use no more than one mechanical switch with a dual-circuit dual tech sensor switch.

3-way installation
For retrofit 3-way installations the mechanical switch needs to be rewired as shown in the diagram below after wiring the dual
tech sensor switch. Otherwise the 3-way installation will not work as expected. Single-pole mechanical switches may also be
used in a 3-way with MS-B102, MS-B102-V and MS-B202 models.

Common
1. Connect Ground: Ensure the bare copper or green ground wire from the wallbox is connected to the green ground screw of
the mechanical switch.
2. Tag circuit Common: Your 3-way mechanical switch should have three screw terminals, two of the same color, and one of a
different color. Tag the wire that is connected to the screw terminal of a different color.
3. Identify the wire that matches the color of the wire you connected to the blue wire of the Maestro dual technology occupancy
sensor switch. Connect this wire to one of the two terminals of the same color.
4. Combine the tagged wire, the remaining wire and yellow jumper wire (included) using a wire connector. Connect the other end
of jumper wire to the different color screw.
