The combination of these technologies helps to eliminate false triggering problems even in difficult applications. The DT200 turns lighting systems on and off based on occupancy and ambient light levels.The DT200 offers numerous operating modes that can be combined to create the ideal custom control. The sensors can be confi gured to turn lighting on, and hold it on as long as either or both technologies detect occupancy. After no movement is detected for the duration of the time delay (5 to 30 minutes) the lights are switched off. A "walkthrough" mode can turn lights off after only 3 minutes, if no activity is detected after 30 seconds of an occupancy detection.The DT200 operates on 24VDC supplied by WattStopper Power Packs. DT200 sensors also have an isolated relay with Normally Open and Normally Closed contacts for interfacing with HVAC or EMS. Note: 24V sensors use the following power pack (Sold Separately): Watt Stopper BZ50
