Unit Description And Operation - LEGRAND WattStopper DW-100-24-LA Installation Instructions Manual

UNIT DESCRIPTION AND OPERATION

The DW-100-24 Dual Technology Low Voltage Wall Switch sensor combines
advanced passive infrared (PIR) and ultrasonic technologies into one unit.
The combined technologies help to eliminate false triggering even in difficult
applications.
Selectable operating modes allow the sensor to turn a load ON, and hold it ON
as long as either or both technologies detect occupancy. After no movement is
detected for the selected time delay, the lights switch off. A "walk-through" mode
can turn lights off after only 3 minutes, if no activity is detected after 30 seconds
following an occupancy detection.
The DW-100-24 has one relay and one ON/OFF button. Pressing the button
toggles the state of the relay.
The DW-100-24 also contains a light level sensor. If adequate daylight is present,
the sensor holds the load OFF until light levels drop, even if the area is occupied.
Users can override this function by pressing the ON/OFF button. See Light Level
Adjustment.
Turning ON the Load (ON Mode)
The DW-100-24 can be programmed for either Auto ON or Manual ON mode. In
either mode, the load can be turned ON or OFF using the ON/OFF button.
With the ON Mode DIP switch in the ON position, the occupant must

the load ON until no motion is detected for the selected time delay.
There is a 30 second re-trigger delay. If occupancy is detected
during the delay, the sensor turns the load back ON. After the re-
trigger delay elapses the ON/OFF button must be pressed to turn
ON the load.
With the ON Mode DIP switch in the OFF position, the load turns ON

and OFF automatically based on occupancy. If the load is turned

OFF manually, Presentation Mode operation applies. This prevents
the load from turning ON automatically after it was deliberately
turned OFF. Pressing the button to turn lights ON returns the
sensor to Auto ON mode.
