Dualtech PIR & 40 kHz Ultrasonic Wall Switch Vacancy Sensor. 1 Button. The DT VS 1 is a line voltage, single relay, Dual Technology (PIR & ultrasonic) vacancy (manual ON) 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 maintain the load ON with either or both technologies. 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 vacancy sensor
- Trigger mode settings enable what sensing 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
- 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
- Re-trigger feature allows the load to turn back ON automatically if motion is detected within 30 seconds after it has automatically switched off the load
