Proposition 65 Warning for California Residents

A line voltage, single relay, Ultrasonic wall switch occupancy sensor to control lighting in commercial spaces. The photocell daylight option keeps the lighting load off when the light level is greater than the threshold level setting.As part of our endeavor to deliver professional lighting and control solutions for the entire enterprise, Crestron is pleased to offer STEINEL PROFESSIONAL products, which are available for sale through authorized Crestron Commercial Lighting system integrators.Based in Germany, STEINEL PROFESSIONAL has been manufacturing lighting controls for over 25 years. Their product offering includes a wide variety of controls and sensors for indoor and outdoor applications.

The US WLS 1 is a line voltage, single relay, Ultrasonic (40 kHz) wall switch occupancy sensor intended to control lighting in commercial spaces. Ultrasonic is used where the sensor will not have a clear line of site of the occupants in the desired coverage area. The hold OFF photocell daylight option will keep the lighting load off when the light level is greater than the threshold level setting. The convenient “Switch Link” feature enables up to four sensors to link together for pier to pier grouping achieving expanded detection zones and multiway switching.The typical application is for small offices, restrooms with two stalls and utility/storage rooms. For best performance use this sensor in enclosed spaces no larger than 15’ x 15’.
