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.
