Which option correctly describes RED flashing?

• A. Awaiting confirmation.
• B. Alarm is being acknowledged.
• C. Unacknowledged alarm supervisory condition.
• D. System reset required.

Answer: (C)

Red flashing shows an alarm that needs attention but hasn’t been acknowledged yet. In alarm monitoring, color signals severity and flashing adds urgency to draw the operator’s eye. When an alarm is triggered, acknowledging it records that the issue has been seen and the flashing usually stops or changes, indicating the status has moved from active to acknowledged. A status described as awaiting confirmation implies a pending action, not an active unacknowledged alarm. An alarm being acknowledged means the operator has already started addressing it, which would not be flashing. A system reset required points to a later step after handling the event, not the unacknowledged alarm condition. So red flashing best represents an unacknowledged alarm supervisory condition, signaling the need for immediate acknowledgment and review.
