Square D® Commercial
Grade Occupancy Sensor
PIR Single Circuit Wall Switch
Square D ® Commercial grade occupancy sensors are designed to
provide maximum energy savings in a format that will complement
any decor. The single circuit passive infrared (PIR) switch installs
quickly in a standard wall box without the necessity of providing a
neutral connection. Low profile sensors are available in white, ivory,
gray, light almond and black with color-matched segmented lens.
Light Level Sensor Mode: Each unit includes an adjustable light
level sensor to hold-off artificial lighting when adequate natural light
is present.
Color Matching Lens: Multi-segmented lens matches switch body
and cover plate to achieve a sleek uniform appearance.

detects when areas are briefly occupied as a result of a person
walking through and turns off lighting based on a shorter time delay.
Audible Alert: Provides gentle notice of impending shut-off.
