The PW-103N Positive Infrared multiway wall switch occupancy sensor from WattStopper has a selectable-intensity LED nightlight (in white, blue, or amber) that provides illumination before a person enters enclosed spaces, such as stairwells, hotel guest room bathrooms, or storage rooms. The sensor also provides full-function multiway control in commercial spaces with more than one entrance or switch location; up to four sensors can be wired together to provide full control from any switch location, such as conference rooms or break rooms. PW-103N is installed using traditional three- and four-way wiring and can achieve energy savings of 50% or more.
