PS-DWS1277W
The Dual Technology Wall Switch Occupancy Sensor provides automatic control
of lighting 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) and ultrasonic technology.
Superior lens design and ultrasonic transducers to provide high resolution for
detecting major and minor motion.
Advanced logic enhances energy savings and user convenience.
Convenient pushbutton 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).
