Square D / Schneider Electric
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.
