The DW-200 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 contains two relays for controlling two independent lighting loads or circuits features our innovative SmartSet??_ technology.
The DW-200 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. Each of the DW-200's relays can control a separate lighting load and each can be set for either automatic or manual-ON. Dual ON/OFF buttons allow the user to manually turn on and off each of the loads. DIP switch settings allow for a variety of control options such as Auto-ON or Manual-ON, walk-through, and test mode.
The DW-200 features a built-in light level sensor that controls the second (secondary) relay. If adequate daylight is present, the sensor will hold secondary lights off until daylight levels drop, providing increased energy savings. The DW-200 satisfies energy codes requiring bi-level or daylight control switching. The two relays in the sensor give it the ability to control two lighting loads independently. This provides A/B switching where the user can achieve half-lighting (or another desired portion) from a single switch.
The DW-200 has the flexibility to work in a variety of applications where one technology alone may not be sufficient. In addition, its dual relays allow bi-level switching or control of a secondary load. Common applications include small and executive offices, small and medium conference rooms and lunch/break rooms. This sensor is also a perfect choice for ADA compliant buildings due to lower mounting height requirements.
