The Commercial Grade PIR Wall Switch Occupancy Sensor provides automatic control
of loads by detecting motion and ambient light within the detection area.
Sensor features include:
One or Two separate relay circuits for independently switching loads
(typically lighting loads) ON or OFF.
180° motion detection using passive infrared (PIR) technology.
Superior lens design to provide high resolution for detecting major and
minor motion.
Advanced logic enhances energy savings and user convenience.
Convenient pushbuttons for manual control.
Automatic adaptive technology adjusts the time delay for maximum energy savings.
Automatic 15 second test mode.
Service Switch (OFF/Auto/ON).
Audible alert 10 seconds before sensor turns loads OFF.
Advanced Lamp Saver mode extends the lamp life in 50/50 bi-level
lighting applications (2 Circuit model only).
