3. Package Contents

Verify that all components are present before beginning installation:

• SWX-121-WH Motion Sensor Light Switch
• Cover Plate (typically sold separately, but implied by "Cover" in components)
• Mounting Screws
• Installation Instructions (this manual)

Note: The product specifications list "Cover, Sensor, Chase Nipple, Lock Nut, Instructions". Assuming "Cover" refers to the faceplate, and "Chase Nipple, Lock Nut" are part of the sensor assembly or mounting hardware. For simplicity, I'll list the main components a user would expect.

4. Product Overview

The SENSORWORX SWX-121-WH is a sophisticated wall switch occupancy sensor designed for efficient lighting control. It integrates Passive Infrared (PIR) technology to detect body heat and movement, along with acoustic detection to sense sound, ensuring comprehensive occupancy sensing. Its compact design allows for easy installation in standard wall boxes.

Figure 4.2: Installation diagram for the SENSORWORX SWX-121-WH. This diagram provides detailed front and side views of the sensor, including dimensions (2.74" height, 1.69" width, 1.39" depth) and labels for components such as the LED indicator, sensor face, button, and break-off bracket ears. The side view emphasizes its shallow design, making it easier to fit into electrical boxes.

Key Features:

• Dual Technology: Combines Passive Infrared (PIR) and acoustic sensing for enhanced detection accuracy.
• Auto-On (Occupancy) Mode: Automatically turns lights on when occupancy is detected.
• Versatile Wiring: Compatible with installations with or without a neutral wire, and allows for reversed line/load connections.
• Wide Voltage Compatibility: Supports 120V and 277V AC systems.
• Shallow Design: Easier installation in standard wall boxes compared to deeper sensors.
• Bat-Wing Lens: Unique lens design provides enhanced peripheral detection.

5. Installation

Before starting, ensure power is OFF at the circuit breaker. This device is designed for single-pole applications.

5.1 Wiring Instructions

1. Turn Off Power: Locate the circuit breaker controlling the light switch and turn it OFF. Verify power is off using a voltage tester.
2. Remove Old Switch: Carefully remove the existing wall plate and unscrew the old switch from the electrical box. Disconnect the wires.
3. Identify Wires:
   • Line Wire: The incoming hot wire from the circuit breaker.
   • Load Wire: The wire going to the light fixture.
   • Neutral Wire (Optional): If present, typically white. The SWX-121-WH can operate with or without a neutral connection.
   • Ground Wire: Bare copper or green wire.
4. Connect Wires:
   • Connect the Line wire to the sensor's designated Line terminal.
   • Connect the Load wire to the sensor's designated Load terminal.
   • If a Neutral wire is present, connect it to the sensor's Neutral terminal. If no neutral is available, the sensor will operate in a no-neutral configuration.
   • Connect the Ground wire from the electrical box to the sensor's ground screw.

   Note: The SWX-121-WH allows for reversal of line and load connections for installation flexibility. Refer to the wiring diagram provided with the product for specific terminal identification.

5. Secure Connections: Ensure all wire connections are tight and secure using wire nuts or screw terminals as appropriate.

5.2 Mounting the Sensor

1. Position Sensor: Gently push the wired sensor into the electrical box, ensuring wires are not pinched.
2. Secure Sensor: Use the supplied mounting screws to secure the sensor to the electrical box. The break-off bracket ears can be removed if needed for multi-gang installations.
3. Install Wall Plate: Attach the decorative wall plate (not included with sensor, but required for finish) over the sensor.
4. Restore Power: Turn the power back ON at the circuit breaker.

6. Setup and Configuration

Upon initial power-up, the sensor will enter a warm-up period. During this time, the LED indicator may flash. Once stable, the sensor is ready for configuration.

6.1 Adjusting Settings

The SWX-121-WH typically has default settings for sensitivity and time delay. Advanced settings may be accessible via specific button press sequences or external configuration tools (if applicable, not specified in product description). For basic operation, the sensor will automatically turn lights on when occupancy is detected and off after a set time delay when the space is vacant.

• Time Delay: This setting determines how long the lights remain on after the last detected occupancy. Common settings range from 30 seconds to 30 minutes.
• Sensitivity: Adjusts the responsiveness of the PIR and acoustic sensors. Higher sensitivity detects minor movements and sounds, while lower sensitivity requires more significant activity.
• Walk-Through Mode: Some sensors offer a short time delay for brief occupancy, like walking through a hallway.

Consult the detailed programming guide or manufacturer's website for specific instructions on adjusting these parameters for your model.

7. Operation

The SENSORWORX SWX-121-WH operates primarily in an auto-on (occupancy) mode, providing hands-free lighting control.

7.1 Automatic Operation

• When a person enters the detection zone, the PIR sensor detects motion, and the acoustic sensor detects sound.
• Upon detection, the lights will automatically turn ON.
• As long as occupancy is maintained (through continued motion or sound), the lights will remain ON.
• After the space becomes vacant for the set time delay, the lights will automatically turn OFF.

7.2 Manual Override

The SWX-121-WH typically includes a manual override button on the faceplate. Pressing this button allows you to:

• Turn lights ON manually if they are OFF (overriding occupancy).
• Turn lights OFF manually if they are ON (overriding occupancy).

Note: Manual override behavior may vary. Some models revert to automatic operation after a period, while others maintain the manual state until another manual press or power cycle.

8. Maintenance

The SENSORWORX SWX-121-WH is designed for minimal maintenance. Regular cleaning can help ensure optimal performance.

• Cleaning: Periodically wipe the sensor lens and faceplate with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the surface or sensor components.
• Obstructions: Ensure that there are no obstructions (e.g., furniture, curtains, tall plants) blocking the sensor's field of view, as this can impair detection.
• Dust Accumulation: Excessive dust on the sensor lens can reduce sensitivity. Clean as needed.

Always turn off power at the circuit breaker before cleaning or performing any maintenance that requires touching the sensor directly.
