UNIT DESCRIPTION AND OPERATION
The DSW Dual Technology 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 when PIR
motion is detected and held ON using either or both technologies. 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 DSW-100 has one relay and one ON/OFF button. The DSW-200 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.
DSW 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 DSW-200, light level only affects the load on Relay 2. Users can overrule
this function by pressing the ON/OFF button. See Light Level Adjustment.
Turning ON the Load (ON Mode)
The relays are programmed independently for either Auto ON or Manual ON. In
either mode, the load can be turned ON or OFF using the ON/OFF button.
With an ON Mode DIP switch in the OFF position, the load turns
Auto ON
ON and OFF automatically based on occupancy. If the load is
DIP 8 OFF
turned OFF manually, Presentation Mode operation applies. This
for Relay 1
prevents the load from turning ON automatically after it was
DIP 9 OFF
deliberately turned OFF. Pressing the button to turn lights ON
for Relay 2
returns the sensor to Auto ON mode.
With an ON Mode DIP switch in the ON position, the occupant
Manual ON
must press the ON/OFF button to turn ON the load. The sensor
DIP 8 ON
keeps the load ON until no motion is detected for the selected
for Relay 1
time delay. There is a 30 second re-retrigger delay. If occupancy
DIP 9 ON
re-triggers during the delay (see Trigger Mode), the sensor
for Relay 2
turns the load back ON. After the re-trigger delay elapses the
ON/OFF button must be pressed to turn ON the load.

manually turned OFF the DSW holds the lights OFF until no motion has been
detected for the duration of the Time Delay. With subsequent occupancy, the
DSW turns the load ON. If both relays are ON and one relay is manually turned
OFF this relay remains OFF until both the Time Delay and retrigger delay expires
for the relay that is ON, after that time the ON Mode control settings again apply.
