SMPS A/C Power fail is not an alarm that requires response.

SMPS A/C Power fail is not an alarm that requires response.

• A. True
• B. False
• C. Not applicable
• D. Sometimes

Answer: (A)

In alarm handling, not every alert needs a manual action from the operator. An AC power fail on an SMPS is typically a status-type condition that the unit handles automatically—often by switching to backup power or entering a safe, continuous mode without requiring human intervention. Because the system is designed to continue operating or gracefully shut down only as needed, this particular alarm doesn’t demand a response from the operator. That’s why the statement is considered true. Choosing that it sometimes requires action would imply variability that isn’t present in this context, and labeling it as not applicable or as something that always requires action would contradict the automatic handling behavior described.
