Setup and Installation
The S-322 shock sensor is designed for integration into existing alarm systems. Professional installation is recommended for optimal performance and safety.
Wiring Instructions
Connect the sensor to your alarm system using the provided wiring harness. Refer to the diagram below for correct wire identification:

Figure 1: S-322 Shock Sensor Wiring Diagram
- RED Wire: Connect to Power + (Positive)
- BLUE Wire: Connect to Signal Output
- BLACK Wire: Connect to Ground
Note: If the connector plug on the sensor does not match your alarm system's input, you may need to cut the wires and splice them directly. Ensure proper insulation for all connections.
Mounting Location
Choose a secure, flat surface for mounting the sensor. For vehicles, common locations include under the dashboard, inside the center console, or near the steering column. For motorcycles, consider a protected area under the seat or within the fairing. For home use, mount on a wall or sturdy surface where vibrations are likely to be transmitted.

Operating Instructions
Functionality
The S-322 shock sensor detects vibrations and impacts. When a significant shock is detected, the sensor outputs a low voltage signal through the BLUE wire, which triggers your connected alarm system.
Adjusting Sensitivity
The sensor features an adjustable sensitivity screw (labeled MIN/MAX) located on the unit. Use a small screwdriver to adjust the sensitivity:
- Turn towards MAX for higher sensitivity (detects lighter impacts).
- Turn towards MIN for lower sensitivity (requires stronger impacts to trigger).
Test the sensitivity after adjustment by gently tapping the protected object (e.g., car body, motorcycle frame) to ensure it triggers at the desired level without false alarms.
Maintenance
- Keep the sensor unit clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Ensure all wiring connections remain secure and free from corrosion.
- Avoid exposing the sensor to extreme temperatures, direct water spray, or harsh chemicals.
- Periodically test the sensor's functionality by triggering it to ensure it is still operating correctly.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Sensor does not trigger alarm. |
|
|

User Tips
- Optimal Placement: For vehicle security, consider mounting the sensor on a solid metal surface that is directly connected to the vehicle's frame to best detect impacts.
- Testing Sensitivity: After installation and adjustment, perform several tests by simulating impacts of varying strengths to ensure the sensor responds as desired without being overly sensitive.
- Compatibility: This sensor is designed to work with various alarm systems. If the plug does not match, the wires can be cut and spliced, ensuring correct polarity (Red for Power+, Black for Ground, Blue for Signal).
