The DW-311 extends control to small and medium-sized applications including rooms with partitions such as restrooms, large offices, conference rooms with cubical walls, and classrooms. This sensor features Wattstopper dual technology, which combines Passive Infrared (PIR) and ultrasonic technologies to detect minor and major movements in spaces that may have obstacles that impede direct line of sight movement to the sensor.
Incorporating lighting controls can result in extra energy savings of 30-40 percent in office environments and 50-70 percent in restroom applications. As buildings upgrade to LED lighting fixtures, these sensors can provide further energy savings when implemented in lighting controls programs. For example, the sensor defaults to manual-on operation so lights turn on only when needed, ensuring energy savings for LED lighting projects and upgrades.
The DW-311 features include:
- Key mode settings: With dual in-line package (DIP) switches, users can adjust to meet their needs with options such as power loss mode, smart light level, and presentation mode. Users can also disable presentation mode, which allows for more consistent auto-on functionality in transient spaces such as restrooms and conference rooms, ensuring that lights come on automatically.
- Vandal resistant and color matched lens: The lens is reinforced to withstand impact and is vandal resistant. Color options with matched lenses can meet any décor.
- Code compliance: Meet local energy code requirements with added dimming capability. The sensor offers a code-compliant (ASHRAE 90.1 and California Title 24) solution for retrofit upgrades.
- Multi-way control: Sensor reduces the number of devices required in a space with full function multi-way control from one to four control locations.
