Intended Use and Compatibility

The alarm siren is dedicated to BMW F-series convertible models and the Mini F57, ensuring consistency with the vehicle's original security system. The component is designed to work with the factory electrical system, integrating with the central locking, sensors, and comfort module without requiring wiring modifications.

Its rear-mounted placement facilitates effective sound dispersion outwards while minimizing the siren's exposure to mechanical damage. This is particularly important for convertibles, where the alarm system is designed to react to intrusions into both the interior and the vehicle's surroundings.

Construction and Performance Parameters

The alarm siren speaker features a construction adapted for operation in variable weather conditions typical for the rear of a vehicle. The housing is designed for mounting in the factory location, simplifying servicing and reducing replacement time. The integrated speaker generates a distinct, easily recognizable warning signal that is clearly audible in urban environments and parking lots.

The component interacts with the vehicle's electronics as intended by the manufacturer, minimizing the risk of diagnostic system errors and unwanted dashboard messages. This ensures that after installation, the full functionality of the factory alarm, including arming, disarming, and intrusion signaling, is maintained.

Condition, Origin, and Practical Application

The alarm siren comes from the original BMW production line, ensuring proper fit with the installation and predictable performance during daily use. The used nature of the part makes it an economical solution while maintaining consistency with the vehicle's factory security system.

This component is particularly suitable in situations where:

• the factory siren has been damaged or no longer responds to alarm arming,
• the vehicle displays errors related to the security system,
• the siren needs replacement after bodywork and paint repairs to the rear of the vehicle.

By retaining the original design, you can expect correct compatibility with existing sensors and control modules, without the need for additional adapters.
