For equipment with ALARM SYSTEMS, interruption of the SUPPLY MAINS for 30 s or less is considered NORMAL CONDITION. 30 s is sufficient time to restore
power to the equipment by either plugging it back into SUPPLY MAINS or having the emergency generator
initiate operation. Equipment with an OPERATOR-exchangeable INTERNAL ELECTRICAL POWER SOURCE, when they can be quickly replaced, is
also expected to maintain its ALARM SETTINGS. The ALARM PRESET is expected to remain unchanged after
such interruptions.
