Which alarm sound indicates a High priority alarm?

• A. No alarm sound
• B. Continuous, slow, beeping alarm sound
• C. Continuous, fast, two-tone beeping alarm sound
• D. Three short, high beeping alarm sound

Answer: (C)

High priority alarms are designed to grab attention quickly with a pattern that clearly signals urgent action. A fast, continuous two-tone signal stands out from other alerts, and the nonstop nature tells you the issue persists until you acknowledge it. The two-tone combination helps distinguish this alert even in a noisy environment, so responders know to act immediately. In contrast, no alarm means nothing is active; a slow, continuous beeping usually indicates a lower-priority notice or advisory; three short beeps often signal a different status or event and don’t convey the same sense of ongoing urgency. So the fast, continuous, two-tone alarm sound best communicates a high-priority condition.
