The DT WLS 2 is a line voltage, two relay, Dual Technology (PIR & ultrasonic) wall switch occupancy sensor intended to control bi-level 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.
PIR & 40 kHz ultrasonic wall switch occupancy sensor
Trigger mode settings enable what sensing technolgies 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%
Bi-level load switching (2 relays)
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
