Dualtech PIR & 40 kHz Ultrasonic Wall Switch Occupancy Sensor. 2 Button. The typical application is for bi-level switching in small offices, conference rooms or break rooms. For best performance use this sensor in enclosed spaces no larger than 20’ x 16’. 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 peer to peer 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
