The battery back-up sounder in a Land Rover Discovery 2 is a security system component that activates an alarm when the vehicle's 12V battery is disconnected, when an attempt is made to disconnect the alarm siren, or when an attempt is made to disconnect the battery back-up sounder itself. The sounder is triggered when the vehicle's exterior is locked using the smart key.
