Setup and Installation
Proper installation is crucial for the performance and safety of your siren system. It is recommended that installation be performed by a qualified professional.
Mounting Components
- Amplifier: Choose a dry, well-ventilated location inside the vehicle, such as under a seat or in the trunk. Ensure it is secured with the provided mounting accessories to prevent movement.
- Speaker: Mount the speaker in a location that allows for clear sound projection, typically behind the grille or bumper of the vehicle. Ensure it is securely fastened and protected from direct impact.
- Handheld Controller: Install the controller holder in an easily accessible location within the driver's reach, ensuring it does not interfere with driving or vehicle controls.
Wiring Instructions
Refer to the wiring harness for color-coded connections. Always disconnect the vehicle's battery before beginning any wiring.
- Power Connection: Connect the red wire (positive) to the vehicle's 12V battery positive terminal, preferably through a fused connection (fuse not included, recommended 20A). Connect the black wire (negative) to a solid chassis ground point.
- Speaker Connection: Connect the speaker wires to the designated speaker output terminals on the amplifier. Observe polarity if indicated.
- Controller Connection: Plug the handheld controller's cable into the corresponding port on the amplifier.
- Light Control (Optional): If using the light control function, connect the light output wires from the amplifier to your auxiliary lights. Ensure the lights' current draw does not exceed 15A.
- Horn Button Integration (Optional): The system can be connected to your car's existing horn button for siren activation. Consult a professional for this integration to avoid conflicts with the vehicle's original horn system.
- Audio Input (Optional): For the audio signal input zoom function, connect your car's audio signal source to the designated input on the amplifier.
After all connections are made, carefully reconnect the vehicle's battery and test the system's functions.
Operating Instructions
The handheld remote controller provides full control over the siren and PA functions.
Controller Functions
- ON/OFF Button: Powers the siren system on or off. The controller buttons will illuminate when powered on.
- Horn Button: Activates a momentary horn sound.
- Siren Tone Buttons: The controller features dedicated buttons for various siren tones. The YHAAVALE 6203 offers 9 distinct alarm tones, including two primary siren types (e.g., Wail, Yelp, Phaser, Horn, Hi-Lo, etc.). Press the desired button to activate the tone.
- Manual Horn/Siren: Some buttons may allow for manual activation of horn or siren sounds by holding them down.
- Microphone (PA System): To use the PA function, press the dedicated microphone button (often indicated by a microphone icon). Speak clearly into the microphone on the handheld controller.
- Volume Control: Use the volume up/down buttons on the controller to adjust the microphone volume for the PA system.
- Light Control Buttons: If connected, use the designated buttons to turn auxiliary lights on or off.
- Audio Input Zoom: If an external audio source is connected, activate this function via the controller to amplify the signal through the speaker.
Observe the work indicator displays on the function keys to confirm active modes.
