6. Setup & Installation
This alarm system is designed for universal 12V motorcycle applications. Professional installation is recommended if you are unfamiliar with motorcycle electrical systems.
6.1. Wiring Diagram (General Guidance)
The system typically connects to your motorcycle's 12V battery. The main control unit and siren have color-coded wires for connection. Refer to the following general wiring guide:
- Red Wire: Connect to the positive (+) terminal of the 12V motorcycle battery.
- Black Wire: Connect to the negative (-) terminal or chassis ground of the motorcycle.
- Other Wires (e.g., Blue, Green, Yellow): These are typically for specific functions like ignition kill, turn signals, or remote start. Consult a motorcycle electrical expert or the specific wiring diagram provided with your product if available for precise connections.
- Siren Wires: Connect the siren's wires to the corresponding output from the main control unit.
- Optional 9V Battery Connector: If using a 9V backup battery (not included), connect it to the provided connector. This can provide power if the main motorcycle battery is disconnected.

6.2. Mounting the Components
- Main Control Unit: Find a secure, hidden, and dry location on your motorcycle, such as under the seat or within a fairing. Ensure it is protected from direct water spray and excessive vibration. The unit is water-resistant, but avoiding direct exposure is best.
- Siren: Mount the siren in a location where its sound will not be muffled and is difficult for a thief to access or disable. Ensure it is securely fastened.
- Wiring: Route all wires carefully, securing them with zip ties or electrical tape to prevent them from chafing, getting caught in moving parts, or being easily cut.

7.1. Remote Control Functions
- Lock Button (Setting): Press once to arm the alarm system. The motorcycle will enter the anti-theft alert state. A short chirp from the siren usually confirms activation.
- Unlock Button (White Alert): Press once to disarm the alarm system and clear the alert state. Two chirps usually confirm deactivation.
