GF80.50-P-6030R Alarm Signal Horn, Component Description

Component Identification:

Location
The alarm signal horn is located in the left fender, behind the fender liner.

Task
The alarm signal horn is connected to the driver-side SAM control unit (N10/10) via a direct data line.Encrypted communication is accomplished via these data lines.
The alarm signal horn is responsible for output of the acoustic alarm for the anti-theft alarm system (ATA) and the panic alarm (only United States of America).

Activation of alarm signal horn
The alarm signal horn is activated by the commands "Activate, doors closed" or "Activate, doors ajar" via the data line. In the active state, the alarm signal horn permanently monitors whether data and supply lines are connected.

Alarm statuses
The alarm statuses are actuated by the driver-side SAM control unit. The signal sequence is controlled by the alarm signal horn and can be programmed for specific countries via STAR DIAGNOSIS.

The panic alarm can also be actuated when the ATA is deactivated.

Self-armed alarm (not United States of America and Japan as of 1.12.06)
The alarm signal horn automatically triggers an acoustic alarm if it recognizes an interruption in its supply and data lines in the activated state.

Internal rechargeable battery (not United States of America and Japan as of 1.12.06)
The rechargeable battery, integrated into the alarm signal horn, is charged as long as circuit 15 is On and the alarm signal horn is deactivated. The charge level can be checked via STAR DIAGNOSIS.

Acoustic feedback (only Netherlands)
The alarm signal horn signals an acoustic feedback (three short buzzing sounds), when it has been activated successfully with the command "Activate, doors closed".
This function and the volume of the feedback are programmable in the ATA variant coding.
