Dual Technology Wall Switch
Occupancy Sensors
DSW-100 DSW-200

Presentation Mode is a feature of the Auto ON mode. When both relays are
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.
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.
Manual ON
DIP 8 ON
for Relay 1
DIP 9 ON
for Relay 2
Auto ON
DIP 8 OFF
for Relay 1
DIP 9 OFF
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.

DSW-200 1 Auto ON 8 OFF
2 Manual ON 9 ON

Alerts
The DSW can provide audible alerts as a warning before the load turns OFF.
High (DIP #4 OFF) Default setting. Suitable for most applications.
PIR Sensitivity Adjustment
The DSW 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.
Time Delay (15 min.
DIP 1 ON & 2 OFF)
Time delays of 5, 15 (default), or 30 minutes are
available. See DIP SWITCH SETTINGS for information.
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.
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.
Low, 50%
(DIP #4 ON)
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.
Audible Alerts
(DIP #7 ON)
No Alerts No warnings provided.
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)
The DSW sensor turns the load OFF 3 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.
No Walk-Through Walk-Through mode disabled.
Shading indicates default operation.
Time Delays
The DSW 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 DSW-200,
both relays use the same delay.

COVERAGE PATTERNS
Coverage testing has been
performed according to the
NEMA WD 7 guideline. For best
performance, use in spaces not
larger than 18’ x 15’.
PIR Sensor
The sensor has a two-tiered,
multi-cell viewing Fresnel lens
with 180 degree field of view. The
red LED on the sensor flashes
when the PIR detects motion.
Masking the lens
Opaque adhesive tape is supplied
so that sections of the PIR sensor’s
view can be masked. You can
eliminate coverage in unwanted
areas. Since masking removes
bands of coverage, take this into
account when troubleshooting
coverage problems.
Ultrasonic Sensor
The sensor has two ultrasonic transceivers operating at 40kHz. Detection
sensitivity can be adjusted using the trimpot under the ON/OFF buttons.
Trigger Mode
The DSW sensor has four occupancy trigger options, set with DIP switches 5 and 6.
Determine the appropriate option using the Trigger 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 Auto On Mode, after the load turns off, detection by the selected
technology within the number of seconds indicated turns the lights back ON. If the
load was configured as Manual ON, the re-trigger time is 30 seconds.

TROUBLESHOOTING
Lights do not turn ON with motion (LED does flash)
1. Press and release each button to make sure that the correct lights
come ON for each relay. If the lights do NOT turn ON, check wire
connections, especially the Load connection. If the lights turn ON, verify
that the correct On Mode is selected in DIP switches 8 and 9.
2. Check to see if light level control is enabled: cover the sensor lens with
your hand. If the lights come ON, adjust the light level setting.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn ON with motion (LED does not flash)
1. Press and release each button. Make sure that the correct lights
come ON for each relay. If the lights turn ON, set PIR and Ultrasonic
Sensitivity to High.
2. Check the wire connections, in particular, the Neutral and Line
connections. Verify that connections are tightly secured.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
ADJUSTMENTS
Sensor Adjustment
Remove the wall plate. Remove the button cap by firmly squeezing together the
top sides of the button assembly. Gently pull it away from the unit.
When the adjustments are completed, replace the button cap by inserting its
hinges into the tabs on the main unit and then squeeze the top of the button while
pressing it into the unit. Reinstall the cover plate.
Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level control and
set the threshold: 1) Make sure the room is lit appropriately. 2) Put the sensor
into TEST mode. You have 5 minutes to complete the procedure. 3) Press and
hold the ON/OFF button (Relay 1button on the DSW-200) for 3 seconds, until
you hear a beep. 4) Step away from the sensor. After 25 seconds a beep sounds,
indicating that the threshold level is set. This threshold is retained, even if power
is lost, until it is re-set or disabled. In the DSW-200, light level control only affects
Relay 2.
To disable light level control, press and hold the Relay 1button for 7 seconds,
until a double beep tone sounds.
Reset to Default
Use the DIP Switch Settings tables on the previous page to return features to
factory settings. To reset the DSW press and hold the ON/OFF button for 10
seconds, until a triple beep sounds. This resets the sensor and disables light
level control (the brightest ambient light will not hold the light OFF).

Lights do not turn OFF
1. There can be up to a 30 minute time delay after the last motion is
detected. To verify proper operation, set DIP switch 1 to ON, then reset
switches 1 and 2 to OFF to start Test Mode. Move out of view of the
sensor. The lights should turn OFF in approximately 5 seconds.
2. Verify that the sensor is mounted at least six feet (2 meters) away from
any heating/ventilating/air conditioning device that may cause false
detection. Verify that there is no significant heat source (e.g., high
wattage light bulb) mounted near the sensor.
3. Verify that the trimpot is not pointing at “Service” (red LED ON). If so,
rotate the trimpot to it’s middle setting (pointing up). The Service setting
allows users to operate the sensor as a service switch in the unlikely
event of a failure.
4. If the lights still do not turn OFF, call 800.879.8585 for technical support.
Sensing motion outside desired areas
1. Select PIR Sensitivity — Low (DIP switch 4 = ON) if necessary.
2. Mask the PIR sensor’s lens to eliminate unwanted coverage area.
3. Adjust the Ultrasonic Sensitivity. Rotate trimpot counterclockwise to
reduce sensitivity.
Red LED is lit all the time and the sensor features don’t work.
1. Check the Ultrasonic trimpot. If it is set at fully clockwise (MIN) the unit is
in Service Mode. Set the trimpot to a mid-range position.
2. If re-setting the trimpot does not clear the LED call technical support.
