Remove Yellow Label
Step 2:
Loosen the Screws and Remove Metal Link
Step 3:
Connect Neutral to Silver Screw and Ground to Green Screw

Notes:
-
Some Pink wires may come as Gray
Black wires can be used interchangeably
• Violet and pink wires are not present on devices without the D option
• Cap off the violet and pink wires if dimming functionality is not being used
• Red Wire is not present on devices without the MWO option
• Cap off the red wire if Multi-Way functionality is not being used
• For ground Multi-Way Configurations ground must come from the same source
• For neutral conversion Multi-Way Configurations power must come from the same panel
• Per NEC requirements, the 0-10V violet, and pink wires must be installed as Class One.
• SPODMRA MWO paired with WSXAMWO will act accordingly with WSXA occupancy settings
• The 0-10V control wires must not exceed 250 ft (76 m) in length and must be sized at no less than 20 AWG
• The Low Voltage Communication BUS must not exceed 250 ft (76 m) in length and must be sized at no less than 20 AWG -
= Occupancy Time Delay
The length of time an occupancy sensor will keep the lights on after it last detects occupancy1- 30 sec| 5 – 10.0 min*| 9 – 20.0 min| 13 – 30.0 min
---|---|---|---
2 – 2.5 min| 6 – 12.5 min| 10 – 22.5 min|
3 – 5.0 min| 7 – 15.0 min| 11 – 25.0 min|
4 – 7.5 min
2 = Occupancy Time Delay (MWO & D Devices)
The length of time an occupancy sensor will keep the lights from dimming to
low trim (S-Code 16) after it last detects occupancy
| 1 – Test Mode | 5 – 7.5 min | 9 – 17.5 min | 13 – 27.5 min |
|---|---|---|---|
| 2 – 30 sec | 6 – 10.0 min* | 10 – 20.0 min | 14 – 30.0 min |
| 3 – 2.5 min | 7 – 12.5 min | 11 – 22.5 min | 1 |
| 4 – 5.0 min | 8 – 15.0 min | 12 – 25.0 min | 1 |
| 4 – 5.0 min |
eg
Test mode sets Occupancy Time Delay to 30 seconds, and increases photocell
transition rate in addition to disabling the microphone on units with Dual
Technology.

= On Mode
WSXA 2P models default Pole 1 Auto On, Pole 2 Manual On.
Automatic On
The sensor automatically turns the lights on when it detects occupancy.
Manual On
The sensor requires pressing the button to turn the lights on.
Reduced Turn-On
The sensor is set to initially only detect large motions, effectively ignoring any reflected Passive Infrared (PIR) signals. Occupants will still be detected immediately when they enter the room as their PIR signal is large. Once the lights are on, the sensor returns to maximum sensitivity.
1 – Automatic On*
3 – Reduced Turn-On
2 – Manual On

= Switch Modes
Switch Enable (Override Off)
The button will turn lights off and keep them off until pressed again. The lights will remain off until the button is pressed again, restoring the sensor to Automatic On mode.
Switch Disable
The user is prevented from turning off the lights via the push button.
Predictive Mode
Pressing the push-button switch overrides the lights off and temporarily disables the occupancy detection. After 10 seconds, the occupancy detection reactivates and monitors for an additional 30 seconds. If no occupancy is detected during this period, the sensor will revert to Automatic On operation. If occupancy is detected, the sensor will remain in Override Off mode and requires the switch to be pressed again in order to restore the sensor to Automatic On.
Predictive Mode with Expiration
Pressing the push-button switch overrides the lights off and temporarily disables the occupancy detection. After 10 seconds, the occupancy detection reactivates and monitors for an additional 30 seconds. If no occupancy is detected during this period, the sensor will revert to Automatic On operation.

OPERATIONAL SETTING INSTRUCTIONS
PLEASE READ ALL 7 STEPS BEFORE PROGRAMMING
- Enter programming mode by pressing & holding buttons until LED flashes rapidly. Release button.
- Enter a specific programming function by pressing the button the number of times as the desired function number from the tables on the following pages (e.g., press twice for function 2, Occupancy Time Delay).
- The selected function’s current setting will then be read out in a sequence of LED flashes (e.g., five flashes for 10 min). To change the setting, proceed to step 4 before the sequence repeats 10 times.
- While the sensor is flashing back the current setting, interrupt it by pressing a button the number of times for the new desired setting as indicated in the particular function’s detailed table (e.g., press seven times for 15 min). The sensor will begin to flash a new setting as confirmation.
- Next, while the sensor is flashing back a new setting, interrupt it by pressing and holding the button until LED flashes rapidly. Release button.
- As final confirmation and activation of the new setting, re-enter the programming function number that was changed (e.g., press twice for function 2, Occupancy Time Delay).
- LED will flash twice indicating acceptance of the new setting. If two flashes are not seen, repeat 7 step process.
Note: To exit programming mode without saving or to change to a different function, wait for the blink-back sequence to repeat 10 times then return to step 1.
