WEIGHT: 5 oz
MOUNTING: Single Gang Switch Box
MOUNTING HEIGHT: 30-48 in (76.2-121.9 cm)

ELECTRICAL SPECS

MAXIMUM LOAD (Relay) 800 W @ 120 VAC / 1200 W @ 277 VAC / 1500 W @ 347
VAC MINIMUM LOAD: None
MOTOR LOAD: 1/4 HP
MAX SINK CURRENT: 50 mA
0-10V DIM MIN OUTPUT: <0.3 V
FREQUENCY: 50/60 Hz (timers are 1.2x for 50 Hz)

ENVIRONMENTAL SPECS

OPERATING TEMP: 14° to 122° F (-10° to 50° C)
RELATIVE HUMIDITY: 20 to 75% non-condensing ROHS COMPLIANT

COVERAGE PATTERN

Small motion (e.g. hand movements) detection up to 20 ft (6.10 m), ~625 ft2
Large motion (e.g. walking) detection greater than 36 ft (10.97 m), ~2025 ft2
Wall-to-wall PIR coverage
Units with -PDT (Passive Dual Technology) option (also called MicrophonicsTM) provide overlapping detection of human activity over the complete PIR coverage area. Advanced filtering is utilized to prevent non-occupant noises from keeping the lights on.

CONVERSION FROM GROUND ONLY (NO NEUTRAL) TO NEUTRAL WIRING
This product is pre-configured for wiring without a neutral with a solid ground; however, if connection to neutral is required by code, the unit easily converts in seconds. AcuityBrands-WSX-D-Dimming-Occupancy-Wall-
Switch-2

WIRING TO GROUND (NO NEUTRAL)

WIRING TO NEUTRAL

NOTE

Do not wire device hot.
Per NEC requirements, the 0-10V violet and pink wires must be installed as Class One.
0-10V Dimming Common from luminaire may be pink or as otherwise indicated per section 410.69 of the 2020 NEC.
The 0-10V control wires must not exceed 250 ft (76 m) in length and must be sized at no less than 20 AWG. 5.) If no neutral is present, unit requires a solid ground connection in order to power up.

TROUBLESHOOTING

Unit does not appear to power up:

Confirm device is properly connected to neutral or ground, per the wiring diagram above.
Confirm all wiring connections and that 120/277VAC is present.

For further troubleshooting guidance, please contact the Controls Technical Support Team 1(800)-535-2465

WSX D INSTRUCTION SHEET

ADAPTIVE DAYLIGHT HARVESTING (ADH)
With Sensor Switch’s Adaptive Daylight Harvesting (ADH), automatic dimming has never been more reliable – even in a wall switch. It works by establishing two state change set-points; daylight and darkness. The light level in the space will then be automatically maintained by intelligently controlling the dim level of the electric light source. Set-points can be established using the “Set Now” option or programmed using desired light levels as measured in foot candles (fc).

PROGRAMMING INSTRUCTIONS

Operational settings can be changed via the push-button sequence outlined below (note the example used is for changing occupancy time delay ). AcuityBrands-WSX-D-Dimming-Occupancy-Wall-Switch-7

OPERATIONAL SETTINGS

2 = Occupancy Time Delay
The length of time an occupancy sensor will keep the lights on after it last detects occupancy.

Test Mode**
30 sec
2.5 min
5.0 min
7.5 min
10.0 min*
12.5 min
15.0 min
17.5 min
20.0 min
27.5 min

22.5 min
25.0 min

**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.

3 = On Mode
Not applicable with Vacancy (VA) Option

Automatic On
Sensor automatically turns the lights on when it detects occupancy.

Manual On
Sensor requires pressing the button to turn the lights on.

Reduced Turn-On
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 lights are on, the sensor returns to maximum sensitivity.

Automatic On*
Reduced Turn-On
Manual On

4 = Switch Modes
Not applicable with Vacancy (VA) Option
Switch Enable (Override Off)
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
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.

5 = Darkness Set-Point / Inhibit Set-Point
The ambient light level at which the sensor sets the lights to the High Trim setting.

**Set Now will automatically select the Darkness Set-Point based on the current conditions in the room. Lights will go to full bright and sensor will rapid flash for 15 seconds allowing occupant to move out of direct view of sensor. Once the set-point selection is completed, the sensor will double- blink in confirmation.

6 = Daylight Set-Point
The ambient light level at which the sensor sets the lights to the Low Trim setting.

Set Now* 5 – 8 fc 9 – 48 fc 13 – 128 fc
2 – 0.1 fc 6 – 16 fc 10 – 64 fc 14- 192 fc
3 – 1 fc 7 – 24 fc 11 – 80 fc 15 – 256 fc

**Set Now will automatically select the Daylight Set-Point based on the current conditions in the room. Lights will go to full dim and sensor will rapid flash for 15 seconds allowing occupant to move out of direct view of sensor. Once the set-point selection is completed, the sensor will double- blink in confirmation.

7 = Photocell Mode

Prevents lights from automatically coming on when light level is above the Inhibit Set-Point Adaptive Daylight Harvesting
Dims lights from high trim to low trim setting according to Darkness and Daylight set-points.
