1. Introduction
Thank you for purchasing the Universal Motorcycle Anti-theft Alarm. This device is designed to provide enhanced security for your motorcycle with features like vibration detection, remote control arming/disarming, vehicle search, and adjustable sensitivity. Please read this manual carefully before installation and operation to ensure proper use and longevity of the product.
2. Package Contents
Please check the package for the following items:
- 1x Alarm Host Unit
- 2x Remote Controls
- 1x Instruction Manual (paper, for reference)

3. Setup and Installation
3.1. Installation Instructions
- Alarm Host Unit Placement: Due to the special structure of the host, it is recommended to install the horn upward for optimal sound projection.
- Antenna Placement: The effective range of the alarm is significantly influenced by its environment. When installing, the antenna (black or green wire) should be suspended and straightened as much as possible, avoiding contact with metal parts of the vehicle.
- Main Engine Fixing: The main engine can be securely fixed by pasting with adhesive or binding with a cable tie. Ensure it contacts the vehicle body as much as possible to facilitate the conduction of vibrations for accurate detection.
3.2. Wiring Diagram
The alarm system operates on a 12V DC power supply. Ensure your vehicle's electrical system matches this requirement. If no corresponding wiring harness is available for certain functions, those functions will not be active.

Wiring Connections:
- Red Wire: Connect to the positive (+) terminal of the 12V battery.
- Black Wire: Connect to the negative (-) terminal of the 12V battery (ground).
- Yellow Wires (x2): Connect each yellow wire to the positive wire of your motorcycle's turn signals. This enables the double blinking function.
- Antenna (Black or Green Wire): This wire should be straightened and suspended for optimal remote control range.
Important: It is recommended to add a 2-amp fuse on the red power wire, close to the battery, for electrical safety.
4. Operating Instructions
The alarm system is controlled via the provided remote controls. Familiarize yourself with the buttons and their functions:
| Remote Control Button | Function | Operation | Concrete Steps |
|---|---|---|---|
| Set Key (Lock icon) | Anti-theft (Arm) | Short click | One horn sound, then enters anti-theft status after three seconds.
|
| Release Key (Unlock icon) | Anti-theft (Disarm) | Short click | Two horn sounds to disarm the alarm. |
| Search Key (Lightning bolt icon) | Search Car | Short click | The horn will sound to indicate the vehicle's location. Press any key to stop. |
| Sensitivity Setting | Hold for three seconds | Long press the search key for 3 seconds until a prompt tone is heard, then release. The system enters sensitivity adjustment mode.
| |
| Start Key (Key icon) | Enable Double Flash | Hold for three seconds | Enables independent double blinking of turn signals. Press any key to exit this mode. This function requires the yellow turn signal wires to be connected. |
5. Maintenance
5.1. Remote Control Battery Replacement
When the remote control's operating range decreases or its indicator light dims, it is time to replace the battery. The remote controls are precision manufactured; avoid dropping them or exposing them to water.
5.2. General Care
Keep the alarm host unit and remote controls clean and dry. Avoid exposing them to extreme temperatures or direct sunlight for prolonged periods.
6. Troubleshooting
- Alarm does not work or remote control has no reaction:
Check all wiring connections (red to positive, black to negative) to ensure they are secure. Verify the battery in the remote control is not depleted and is correctly inserted. - Alarm is too sensitive, triggers with slight wind:
Adjust the sensitivity setting using the Search Key (refer to Section 4). If the alarm is mounted on plastic fairings, consider relocating it to the motorcycle's chassis, as plastic can amplify vibrations or flex with wind. - Certain functions do not work:
Ensure all necessary wires are connected. For example, the double flash function requires the yellow wires to be connected to the turn signals. If a specific wiring harness is not present, the corresponding function will not be available. - Alarm sounds weak or distorted:
Check the alarm host unit for any obstructions around the horn. Ensure it is mounted upward as recommended.

8. User Tips
- Mounting Location: For optimal performance and to reduce false alarms from wind, consider mounting the alarm host unit directly on the motorcycle's chassis rather than on plastic fairings.
- Antenna Range: To improve the remote control's range, ensure the antenna wire (black or green) is fully straightened and suspended, avoiding contact with metal. Some users have found extending this wire can further enhance range.
- Electrical Safety: Always install a 2-amp fuse on the red power wire, as close to the battery as possible, to protect your motorcycle's electrical system.
- Sensitivity Adjustment: Experiment with the sensitivity settings to find the ideal balance for your environment, preventing false alarms while ensuring effective theft detection.
