STEINEL US WLS 1 Ultrasonic Wall Switch Occupancy Sensor, White
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 endeavour 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’.

Key Features
- 40 kHz ultrasonic wall switch occupancy sensor
- Adjustable ultrasonic reach setting from 25% to 100%
- Line voltage lighting control (120/230/277 VAC, 50/60 Hz)
- 180° coverage pattern
- Manual ON or Automatic ON option
- Light level feature keeps lights OFF when sufficient daylight is present
- Mounts to a single-gang NEMA-style, standard switch box & decorator-style wall plate by others
- “Switch Link” communication allows for up to 4 sensors to be grouped together
- IQ Mode dynamically adjusts the ‘ON’ time delay by learning individual room occupancy
- Walk through mode option will switch the load OFF in 3 minutes if no additional detection occurs after the first 30 seconds
- Audible alert feature provides an audible warning that the load will shut-OFF in 10 seconds unless additional motion is detected
- Visible alert feature provides a momentary OFF/ON blink, warning that the load will shut OFF in 10 seconds unless additional motion is detected
- Service mode option deactivates the automated functions of the sensor and the load is only manually controlled using the ON/OFF button
