YOur original bus failure on BUS 0, is the programming keypad usually. If the programming keypad is plugged in to the panel during the power up phase of the installation, it will scan it in as part of the system so when it is removed there will be a failure because the system can no longer see it. You did the right thing by deleting it. As far as your AM fail.... AM is ( automation module) correct. Your concord scans and checks in with all devices connected to the system every 12 hours. If this is not connected properly, or not at all connected it will show the failure. Make sure that everything is properly connected before power up on the panel.
