Alarm activated by alarm signal siren, function - GF80.50-P-3026S

MODEL 215, 220 with CODE (491) USA version 

MODEL 215, 220 with CODE (551a) Anti-theft alarm (ATA) 

The alarm signal siren with additional battery (H3/1) can trigger an alarm automatically  . This is the case when the ATA is activated and

• the connection lines to the siren are disconnected,
• the vehicle battery is disconnected.

The siren sounds an acoustic alarm  . (Due to the rechargeable battery the siren is capable of triggering an alarm even when the power supply is disconnected).

The siren sets the front left SAM control module (N10/6) to the alarm state and triggers an optical alarm. If the connection between the siren and the PSE control module (combined) (A37) is interrupted, the SAM recognizes this interruption and triggers the alarm anyway.

A triggered alarm can only be terminated by deactivating  or resetting  the ATA.
