Hi Flying Bull
Check out the Battery Backup Relay 1715PA - If the essential bus bars are disconnected, this relay provides power to the bus tie system and the warning unit direct from the battery hot bus. Whilst it doesn't help if the battery is flat, I believe it does supply power to the warning unit if the essential bus bars are taken out of the equation.
Cheers
