Setup and Installation
The SENSORWORX SWX-852-2-WH is designed for straightforward installation in a standard single-gang wallbox, requiring less than 1 inch of mounting depth.
1. Wiring
- Turn off power: Before starting, ensure power to the circuit is OFF at the circuit breaker.
- Identify wires: The SWX-852-2-WH is line-powered and requires connection to line (hot) and neutral wires. It does not directly switch the load.
- Connect wires: Use the provided wire nuts to connect the switch's wire leads to the corresponding building wiring (Line, Neutral). Consult local electrical codes for proper wiring practices.
- Mount the switch: Carefully place the switch into the wallbox, ensuring wires are not pinched. Secure the switch to the wallbox using the provided mounting screws.
- Install wallplate: Attach a standard decorative wallplate (not included) over the switch.
- Restore power: Turn power back ON at the circuit breaker.

2. Pairing with Wireless Controller
The SWX-852-2-WH must be paired with a compatible SENSORWORX wireless load controller (e.g., SWX-950 series power pack, SWX-851 wireless wall switch, or SWX-874-ELV dimmer) to function. The pairing process is quick and typically takes approximately 3 seconds per device.
- Ensure power is on for both the SWX-852-2-WH and the target wireless load controller.
- Initiate pairing mode on the wireless load controller according to its specific instructions. This usually involves pressing and holding a button on the controller.
- Activate pairing on SWX-852-2-WH: Press and hold the designated button on the SWX-852-2-WH (refer to the specific button layout on your device) until an indicator light confirms pairing mode.
- Confirm pairing: Both devices should provide visual feedback (e.g., LED flashes) to indicate successful pairing. Refer to the controller's manual for specific confirmation signals.
For multi-way switching, additional SWX-852-2-WH units can be paired to the same wireless load controller.
Operating Instructions
Once installed and paired, the SWX-852-2-WH operates as a remote control for the linked SENSORWORX wireless load controller.
- ON/OFF Control: Press the top button to turn the connected lights ON. Press the bottom button to turn the connected lights OFF.
- Dimming Control (if paired with a dimmer): If paired with a compatible SENSORWORX wireless dimmer (e.g., SWX-874-ELV), the buttons may also provide dimming functionality. Typically, holding the ON button will brighten lights, and holding the OFF button will dim lights. Refer to the dimmer's manual for specific dimming operations.
- Multi-Way Control: In multi-way setups, any paired SWX-852-2-WH switch can control the same lighting load.
Maintenance
The SENSORWORX SWX-852-2-WH is designed for long-term, maintenance-free operation. Follow these guidelines for optimal performance:
- Cleaning: To clean the surface of the switch, use a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish.
- No User Serviceable Parts: There are no user-serviceable parts inside the switch. Do not attempt to open or repair the device.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
Troubleshooting
If you experience issues with your SENSORWORX SWX-852-2-WH, consult the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not respond to presses. | No power to the switch. Not properly paired with a controller. Controller is out of range or powered off. | Verify power at the circuit breaker and wiring connections. Re-attempt the pairing process with the wireless load controller. Ensure the wireless load controller is powered on and within range (~40 feet through obstructions). |
| Lights do not turn ON/OFF or dim correctly. | Incorrect pairing. Incompatible controller. Interference. | Confirm successful pairing with the correct SENSORWORX wireless load controller. Ensure the controller is compatible with the SWX-852-2-WH and supports the desired functionality (e.g., dimming). Minimize sources of wireless interference (e.g., large metal objects, other 900 MHz devices). |
| Intermittent operation. | Weak wireless signal. Environmental factors. | Relocate the wireless load controller or the SWX-852-2-WH to improve signal strength. Ensure no new obstructions have been introduced. Check for extreme temperatures or humidity outside of specified operating conditions. |
