Sensor Switch Load Type: Designed for use with permanently installed incandescent, halogen, MLV, ELV, CFL, LED, magnetic fluorescent, and electronic
fluorescent lighting loads.

When controlling light and fan loads simultaneously on a single-circuit, maximum load capacity per circuit is 4.4 A at 120 V~.
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 (LutronR P/N
50013614) that can be ordered through Tech Support (1.800.523.9466). 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).
