Subclause 6.5.5 – Interruptions of less than or equal to 30 s

הכותרת צריכה לרמז על התוכן. התוכן הוא תהליך שמירת מקור כוח – לאו דוקא בהיבט של התרעות

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.
