Activating Alarm Signal Siren, Function

When the anti-theft alarm (ATA) is activated, the ATA control module (N26) also activates the alarm signal siren with additional battery (H3/1). For this purpose it sends a command to the siren.
The siren is activated by this command.

Since the siren continuously monitors its power supply and data lines, it is also capable of triggering an alarm itself.

The alarm signal siren with additional battery (H3/1) indicates that the ATA has been successfully activated by beeping quickly three times. This signal is not given when one of the doors it not properly closed when the ATA is activated.


NOTE: The siren remains active until it is again deactivated by the ATA.
