Which sound corresponds to a Low 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: (A)

Low priority alarms are kept quiet to avoid distracting operators during routine or less critical issues. The system still signals problems, but without an audible alert, typically using visual indicators or logs so that technicians can check them at a convenient time. The other sounds represent higher levels of urgency: a continuous, slow beeping would draw attention for a less urgent fault, a continuous, fast two-tone beep signals a more immediate issue requiring quick action, and three short high beeps provide a brief, sharp alert for a more serious condition. So, no alarm sound best matches the lowest priority scenario.
