Square D® Wall Switch
Occupancy Sensor
Square D ® Wall Switch Occupancy Sensors employ the latest passive
infrared (PIR) technology to automatically control lighting for areas up
to 1000 square feet, achieving energy savings and convenience.
Each Sensor employs a special 180˚ multi-segmented lens and PIR
motion detector circuit to detect when a person enters an office,
conference room or classroom, and automatically turns on lighting in
that room. This unit will automatically switch the lights off after a preset delay if no motion is detected.
The Square D Wall Switch Occupancy Sensor fits in place of existing
wall switches, connecting to existing active line and ground wiring
similar to a typical wall switch. The Square D Automatic Wall Switch
Occupancy Sensor is the simplest way to achieve energy-saving
lighting control with minimal installation time.

To assure long relay life, Square D has developed a low energy
switch circuit to assure maximum contact life. These sensors are
compatable with electronic and magnetic ballast loads.
