How It Works

The 504D monitors impacts and vibrations to your vehicle:

• Light impacts trigger a warning chirp or Warn Away response
• Heavy impacts trigger the full alarm system

This helps deter theft attempts, vandalism, and break-ins before damage occurs.

Compatibility

Compatible with many popular security brands including:

• Viper
• Python
• Avital
• Clifford
• Automate
• Most aftermarket alarms with standard 4-pin sensor inputs

The included harness allows simple plug-and-play installation on compatible systems, while the connector can also be hardwired for universal applications.

Installation Notes

The 504D should be mounted securely inside the vehicle cabin away from moving components. Sensitivity can be adjusted to prevent false alarms while still providing strong protection against real impacts and intrusion attempts.
