The DW-100 dual technology wall switch sensor combines the benefits of passive infrared (PIR) and ultrasonic technologies to turn lights ON and OFF based on occupancy. It is characterized by high sensitivity to small and large movements, appealing aesthetics, and variety of features.

The DW-100 fits in a single gang junction box. By default, when both PIR and ultrasonic technologies detect occupancy, lights turn ON automatically. Once the lights are ON, detection by either technology holds lights ON until occupancy is no longer detected and the time delay elapses. Through DIP switch settings, the user can customize the sensor by choosing the combination of technologies to turn -ON and hold-ON lights. Additional DIP switch settings allow for a variety of control options such as Auto-ON or Manual-ON, walk-through, and test mode.

Using SmartSet technology, the DW-100 continuously monitors the controlled space to identify usage patterns and automatically adjust the time delay for optimal energy efficiency. The sensor assigns short delays (as low as seven minutes) for times when the space is usually vacant, and longer delays (up to 30 minutes) for busier times. SmartSet is also able to differentiate electrical noise from human motion for greater performance.

Watt Stopper��_s dual technology has the flexibility to work in a variety of applications where one technology alone may not be sufficient. Common applications include small and executive offices, small and medium conference rooms and lunch/break rooms. In addition, dual technology sensors are the perfect choice for ADA compliant buildings due to lower mounting height requirements.
