5. Electrical Wiring:
   • Connect the positive (+) wire from the compressor to a 12V power source (e.g., vehicle battery) via the included 30-ampere in-line fuse.
   • Connect the negative (-) wire from the compressor to a suitable ground point on the vehicle chassis.
   • Wire the horn activation switch (not included, typically a momentary switch) to control the compressor's power supply.
6. Test System: Once all connections are secure, reconnect the vehicle's battery and test the horn. Listen for any air leaks and ensure the compressor builds pressure correctly.

4. Operating Instructions

The VEVOR 4 Trumpet Train Air Horn Kit is designed for simple operation, providing a powerful warning signal when needed.

4.1. Basic Operation

• Ensure the compressor is powered on and the air tank is pressurized. The compressor will automatically stop when the pressure reaches 120 PSI.
• Activate the horn by pressing the connected horn switch. The air will be released from the tank through the trumpets, producing a loud sound.
• Release the switch to stop the horn sound. The compressor will automatically repressurize the tank if needed.

Figure 4.1: The horn produces a loud, effective sound (up to 150 dB) suitable for various situations such as warning animals, in stormy weather, at sharp corners, or in traffic jams.

4.2. Sound Output

The horn kit produces a sound level of up to 150 decibels, making it audible from several kilometers away. This high sound output is intended for effective warning in critical situations.

4.3. Compressor Functionality

The 120 PSI air compressor features an automatic safety protection design. It will automatically cease pumping once the air pressure inside the tank reaches 120 PSI, preventing over-pressurization. It also has an oil-less design and an automatic reset overload protector for enhanced durability and safety.
