What is alarmACmains?
This is the well-known alarm indicating AC mains voltage has dropped below a critical level or that one or more input phases has been lost entirely. An admin treats this as the primary trigger event for a battery-backup scenario, since it directly precedes the rectifiers losing their AC source.
