A powerful “one-two” combination for optimum energy management. Our new Dual Technology Wall Switch Sensors give you the most sensitive and consistent way to manage lighting energy consumption in a wide variety of commercial applications, from small offices and executive suites to conference rooms and break rooms. They do it through dual technology design that combines both passive infrared (PIR) and ultrasonic technologies to give you high sensitivity to small and large movements and wide dense detection, turning lights ON and OFF based on a more accurate, dependable sensing of room occupancy. And installation/switchout is fast and easy with compact product design that fits into existing boxes. Most importantly, the combination of PIR and ultrasonic technologies in both the WDT100 and WDT200 gives you two ways to detect occupancy and turn lights on automatically, then turn them off when no occupancy is detected. PIR technology detects the infrared energy from a human body in motion, and ultrasonic technology spreads coverage over a wider area and detects smaller movements to time the ON/OFF function more efficiently.
WDT100W
Two technologies providing ultimate control.
designed to be better.
At a time when energy management is a top priority, the WDT100 and WDT200 give you a powerful combination of benefits to control lighting
costs with tremendous consistency and accuracy.
YOU CAN CHOOSE from four control options to set the time delay between ON/OFF once occupancy has been detected for each of these sensors:
Choice of auto-ON or manual-ON operation
Sensitivity adjustment
■■ Self-adaptive technology provides an intuitive way to save
energy with continual monitoring that:
Self-adaptive technology for automatic, intuitive energy savings
The WDT200 gives you bi-level control of two loads independently from the same box
– Adjusts time delays automatically based on actual usage patterns;
– Assigns short delays (as low as 7 minutes) when the space is typically vacant, and longer delays (up to 30 minutes) for busier times; and
– Differentiates electrical noise from human motion.
■■ Fixed — 5, 15, or 30 minutes
■■ Built-in sensor holds
secondary lights off until daylight levels drop
Color-matched lenses and low profile for appealing design
■■ Walk-through mode — turns lights off 3 minutes after the room
is initially occupied if no motion is detected after 30 seconds
■■ Each relay can be set for
■■ Test mode — allows quick and easy adjustments
automatic or manual ON
■■ Dual ON/OFF buttons can
control each of the loads manually as well
Fast, easy installation/ switch-out
