UNIT DESCRIPTION AND OPERATION
The DW Dual Technology Multi-Way Wall Switch sensors combine 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. The DW Dual
Technology Multi-Way Wall Switch Occupancy Sensor allows for up to 4 sensors
to be connected to the same circuit. The first sensor to detect occupancy will
turn ON all the lights that are connected to the same circuit. After the room is
unoccupied, the last sensor that detected occupancy turns OFF all the lights
once the time delay has expired. The occupant can turn OFF the load at any time
by pressing the ON/OFF button of any sensor that is connected to the circuit. 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-103 has one relay and one ON/OFF button. The DW-203 contains
two relays and two ON/OFF buttons to allow control of one or two loads
independently. Pressing a button toggles the state of the corresponding relay.
DW sensors contain 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. In
the DW-203, light level only affects the load on Relay 2. Users can overule this
function by pressing the ON/OFF button. See Light Level Adjustment.
Time Delays
The DW sensor holds the load ON until no motion is detected for the selected
time delay. Select the time delay using DIP switch settings. In the DW-203, both
relays use the same delay.

Fixed Time Delay
(DIP 1 ON, 2 OFF)
Time delays are 5,
15
(default), or 30 minutes.
Test Mode
(DIP 1 OFF, 2 OFF)
A Test Mode with a short time delay of 5 seconds
is set when DIP switches 1 & 2 are OFF. It cancels
automatically after ten minutes, or when you set a
fixed time delay. When the Test Mode times out, the
sensor will assume a 20 minute time delay. To restart
Test Mode, change the time delay setting to any fixed
amount and then return it to the Test setting.
Shading indicates default operation and switch setting.
