At a Glance

Crestron® STEINEL DT WLS 1 Dual Technology Wall Switch Occupancy Sensor with 180 degree coverage pattern and line voltage lighting control

Proposition 65 Warning for California Residents

A line voltage, single relay, Dual Technology (PIR & ultrasonic) wall switch occupancy sensor to control lighting in commercial spaces. The photocell daylight option will keep 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 DT WLS 1 is a line voltage, single relay, Dual Technology (PIR & ultrasonic) wall switch occupancy sensor intended to control lighting in commercial spaces. The combination of both technologies enhances occupancy detection in difficult applications. DIP switch adjustable technology options to initiate the load ON and maintain the load ON with either or both technologies. 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, conference rooms and break rooms. For best performance use this sensor in enclosed spaces no larger than 20’ x 16’.For additional information and resources, please visit http://www.steinel.net/DT_WLS_1.

Key Features

PIR & 40 kHz ultrasonic wall switch occupancy sensor

Trigger mode settings enable what sensing technologies are used to initially turn the load ON and what technologies are used to keep the load ON

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
