Setup and Installation
The siren speaker is designed for installation in any vehicle equipped with a 12V DC power supply, such as cars, trucks, motorcycles, RVs, boats, or yachts.
- Mounting the Speaker: Securely mount the siren speaker in a suitable location on your vehicle using its integrated bracket. Ensure it is positioned to project sound effectively and is protected from excessive moisture or direct impact.
- Power Connection: Connect the siren's power wires directly to a 12V car battery. It is recommended to include an inline fuse (not supplied) for protection.
- Wiring Verification: Double-check all wiring connections to ensure they are correct and secure. Incorrect wiring will prevent the unit from functioning.
- Short Circuit Prevention: Take care to avoid any short circuits with the speaker wires during and after installation.

Operating Instructions
The siren horn is operated using the included wireless remote control. The remote features four buttons (A, B, C, D) to activate different tones.

- Button A: Activates Tone 1 (e.g., Horn sound).
- Button B: Activates Tone 2 (e.g., Fire Alarm sound). Press this button again to stop the siren.
- Button C: Activates Tone 3 (e.g., Ambulance sound).
- Button D: Cycles through 4 different tones (e.g., Traffic, Police, etc.). Each press will switch to the next tone in the sequence.
Ensure the remote control has a clear line of sight or is within effective range of the siren receiver for optimal performance.
Maintenance
To ensure the longevity and proper functioning of your DriSentri Car Siren Horn, follow these general maintenance guidelines:
- Cleaning: Keep the speaker and remote control clean and free from dust and debris. Use a soft, dry cloth for cleaning. Avoid harsh chemicals or abrasive materials.
- Moisture Protection: While the unit is designed for vehicle use, avoid exposing it to excessive moisture or direct water spray, especially the remote control.
- Wiring Inspection: Periodically inspect all wiring connections for any signs of wear, corrosion, or damage. Ensure connections remain secure.
- Battery (Remote): If the remote control's range or responsiveness decreases, consider replacing its internal battery (type not specified, typically a small button cell).
