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. It also
includes an isolated relay. The relay follows the state of the
sensor only and is not affected by the switch.
Additionally, the DW-100-24 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.
Manual ON
DIP#8 ON
With the ON Mode DIP Switch in the ON position, the occupant must press the ON/OFF button to turn ON
the load. The sensor keeps 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.
Auto ON
DIP#8 OFF
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.
Presentation Mode
This is a feature of the Auto ON mode. When the relay is manually turned OFF the DW holds the lights OFF until no motion has been
detected for the duration of the Time Delay. With subsequent occupancy, the DW turns the load ON.
Time Delays
The DW-100-24 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-200, both relays use the same delay.
NOTE: Shaded cells below indicate default operation and switch setting.
Test/20 min
(DIP#1 & 2 OFF)
A Test Mode with a short time delay of five 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.
Fixed Time Delay
(DIP#1 ON, & 2 OFF)
Time delays of 5, 15 (default), or 30 minutes are available. See DIP SWITCH SETTINGS for information.
