DESCRIPTION AND OPERATION
The PW-203 Passive Infrared Multi-Way Dual Relay
Wall Switch sensors use advanced passive infrared
(PIR) technology. The PW-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.
The relays can also turn loads ON and OFF
automatically with occupancy. They can be set to
manual or automatic-ON operation independently
from each other, allowing for bi-level control.
Up to four PW-203 sensors can be connected to the
same circuit. When set for Automatic-ON, the first
sensor to detect occupancy turns ON all the lights
that are connected to the same circuit. The occupant
can turn OFF the load at any time by pressing the

SPECIFICATIONS
ON/OFF button of any sensor that is connected to the circuit. If the occupant forgets to turn OFF the lights, the last sensor to detect
occupancy turns them all OFF after the time delay expires.
A Walk-Through mode can turn lights OFF after only 3 minutes, if no activity is detected after 30 seconds following an occupancy
detection.
PW 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 PW-203, light level only affects the load on Relay 2. Users can overrule this function by pressing the ON/OFF
button. See Light Level Adjustment.
Presentation Mode
This is a feature of the Auto ON mode. When both relays are manually turned OFF the PW holds the lights OFF until no motion has
been detected for the duration of the Time Delay. With subsequent occupancy, the PW 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.
Time Delays
The PW sensor holds the load ON until no motion is detected for the selected time delay. Both relays use the same delay. Select the
time delay using DIP Switch Settings.
NOTE: Shaded cells below indicate default operation and switch setting.
Test Mode
(DIP# 1, 2, & 3 OFF)
A Test Mode with a short time delay of 5 seconds is set when DIP switches 1, 2, & 3 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
Time delays are 5, 10, 15, 20 (default), 25, or 30 minutes. See table in Installation section for DIP settings.
(DIP 1 ON, 2 & 3 OFF)
Service Mode
(DIP# 1, 2, & 3 ON)
Service bypasses occupancy and light level functions. Control the load manually using ON/OFF button. Red
LED is always lit when the PW is in Service mode.
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# 4 ON)
No Walk-Through
(DIP# 4 OFF)
The PW 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.
PIR Sensitivity Adjustment

(6.1m)
35’
)
(4.5m)
The PW 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 #5 OFF)
Low, 50%
(DIP #5 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 PW can provide audible and/or visible alerts as a warning before the load turns OFF.
Visible Alert
(DIP #6 ON)
No Visible Alerts
When only one minute is left in the time delay, the load connected to the relay turns OFF for one second.
This provides a one minute warning before the load(s) are turned OFF by the sensor.
No visible warnings provided.
(DIP #6 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 WalkThrough is active, the unit beeps three times at 10 seconds before the load goes OFF.
*If Visible Alert is also ON, the one-minute time-out warning beep is replaced by the visible alert.
No audible warnings provided.
(DIP #7 OFF)
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)
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.
Manual ON
(DIP #8 ON for Relay 1)
(DIP #9** ON for Relay 2)
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 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.
** Switch 9 default is ON for Manual ON functionality of Relay 2 to comply with California Energy Commission Title 24 bi-level switching
requirements.

COVERAGE PATTERNS
Coverage testing has been performed according to the NEMA WD 7
guideline. For best performance, use in spaces not larger than
15' x 12'.
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. This allows you to eliminate coverage
in unwanted areas. Since masking removes bands of coverage,
remember to take this into account when troubleshooting coverage
problems.

1. Make sure that the power has been turned OFF at the circuit breaker.
2. Connect wires to the PW flying leads as shown in the wiring diagram.
The ground wire (green) must be fastened to ground for the
sensor to work properly.
3. Attach the sensor to the wall box by inserting screws into the two wide holes on the top and bottom of the attached metal bracket.
Match them up with the holes in the wall box and tighten.
4. Turn the circuit breaker ON. Wait one minute, then push the Auto ON/OFF switch for each load and the lights will turn ON. There
is a delay due to initial power-up of the sensor that only occurs during installation.
5. Test and adjust the sensor if necessary.
6. Attach the cover plate.
Important: Wire the remote unit to the same branch circuit as the main unit controlling the load. If Relay 2 of the main
unit cannot be controlled from the remote unit, check wiring to be sure both units are on the same branch circuit.
WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.

ADJUSTMENTS
3
Sensor Light Level Adjustment
The light level can be set with loads ON or OFF. The light level feature operates as a Hold OFF function, meaning that once the light
level in a room reaches a set point the lights will not turn ON until the light level drops below the set point. In order to achieve the
maximum energy savings that the light level feature offers, pick a time during the day when there is enough ambient light in the room to
perform the necessary tasks without the aid of artificial light. In order to set this as the threshold level of brightness so that the artificial
lights remain OFF, perform the following steps:
1. Make sure the room is lit appropriately.
2. Put the sensor into TEST mode using the Time Delay DIP Switches.
3. Press and hold the ON/OFF button (Relay 1 button on the PW-203) 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 PW-203, light level control only affects Relay 2.
5. Set the Time Delay DIP Switches to the desired delay time.
To Disable Light Level Control
Press and hold the Relay 1 button for 7 seconds, until a double beep sounds.
Reset
Use the DIP Switch Settings Table to return features to factory settings. To reset the PW, 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).
TROUBLESHOOTING
Lights do not turn ON with motion (LED does ash)
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 the correct On Mode is selected in DIP switches 8 and 9.
• 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.
2. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn ON with motion (LED does not ash)
1. Press and release each button to make sure that the correct lights come ON for each relay. If the lights turn ON, verify that
Sensitivity is on High.
2. Check the wire connections.
• Verify the ground connection.
• Make sure line and load are not reversed.
• Confirm that connections are tightly secured.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
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, 2, and 3 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. 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 5 = ON) if necessary.
2. Mask the PIR sensor’s lens to eliminate unwanted coverage area.
Red LED is lit all the time and the sensor features don’t work.
1. Check DIP switches 1,2,3. If they are all ON the unit is in Service Mode. Set the DIP switches to a valid Time Delay setting.
2. If re-setting the Time Delay switches does not clear the LED call technical support.
