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

DW-103 Single Relay

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

DW-203 Dual Relay

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.

Turning ON the Load

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. In either mode, the load can be turned ON or OFF using the ON/OFF button.

Auto ON

(DIP# 8 OFF for Relay 1)
(DIP #9** OFF for Relay 2)

Manual ON
(DIP #8 ON for Relay 1)

(DIP #9** ON for Relay 2)

With an 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.

With an 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-retrigger delay. If occupancy re-triggers during the delay (see Trigger Mode), 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.

** DW-103: DIP Switch 9 is not used. DW-203: DIP Switch 9 default is ON to comply with CA Energy Commission Title 24 bi-level
switching requirements.

2 Manual ON 9 ON

Presentation Mode

This is a feature of the Auto ON mode. When both relays are 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. If both relays are ON and one
relay is manually turned OFF this relay remains OFF until both the Time Delay and the retrigger delay expire for the relay that is ON.
After that time the ON Mode control settings again apply.

NOTE: Shaded cells below indicate default operation and switch setting.

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.

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.

Time Delay / 15 min.

Time delays of 5, 15 (default), or 30 minutes are available. See DIP SWITCH SETTINGS for information.

(DIP# 1 ON & #2 OFF)

Walk-Through

The Walk-Through mode shortens the time delay to reduce the amount of time the load is ON after a brief moment of occupancy, such
as returning to an office to pick up a forgotten item, then immediately exiting.

Walk-Through Mode
(DIP# 3 ON)

No Walk-Through

The DW sensor turns the load OFF three minutes after the area is initially occupied, if no motion is detected
after the first 30 seconds. If motion continues beyond the first 30 seconds, the set time delay applies.

Walk-Through mode disabled.

(DIP# 3 OFF)

PIR Sensitivity Adjustment

The DW sensor constantly monitors the controlled environment and automatically adjusts the PIR to avoid common ambient conditions
that can cause false detections, while providing maximum coverage.

High

Default setting. Suitable for most applications.

(DIP #4 OFF)

Low, 50%

(DIP #4 ON)

Reduces sensitivity by approximately 50%. Useful in cases where the PIR is detecting movement
outside of the desired area (also consider masking the lens) and where heat sources cause unnecessary
activation.

Alerts

The DW can provide audible alerts as a warning before the load turns OFF.

Audible Alerts
(DIP #7 ON)

No Audible Alerts

Unit will beep at one minute, at 30 seconds, and at 10 seconds before turning OFF load. When
Walk-Through is active, the unit beeps three times at 10 seconds before the load goes OFF.

No audible warnings provided.

(DIP #7 OFF)

Trigger Mode

The DW sensor has 4 occupancy trigger options, set with DIP Switches 5 and 6. Determine the
appropriate option using the Trigger Mode matrix.

In the Trigger Mode DIP Switch setting table, in order to deem the area occupied:

• Both requires motion detection by the PIR and the Ultrasonic.

• Either requires motion detection by only one technology.

• PIR requires motion detection by the PIR.

Initial Occupancy: The method that activates a change from “Standby” (area unoccupied and
load OFF) to “Occupied” (area occupied and load may turn ON).

Maintain Occupancy: The method indicating that the area is still occupied and the lights should
remain ON.

Re-trigger: In Manual ON mode, after the load automatically turns OFF, detection by the
selected technology within 30 seconds automatically turns the lights back ON. In Auto ON mode, after the load turns OFF automatically,
detection by the selected technology turns the lights back ON.
