Which alarm sound corresponds to a Test failure event?

• A. Continuous, slow, beeping alarm sound
• B. Continuous, slow, two-tone beeping alarm sound
• C. Continuous, fast beeping alarm sound
• D. Long, low beep; then one high beep

Answer: (B)

In alarm sound languages, the pattern, cadence, and tones cue what happened without needing to read text. For a test failure, the distinct pattern is a continuous, slow two-tone beeping. The two different tones flag a fault in the test process, while the slow pace keeps it clear that this is not an immediate life-safety alarm but a test-related issue that needs attention. The continuous nature shows the condition persists until someone responds. The other patterns don’t carry that same combination: a slow single-tone could be confused with other faults, a fast beeping sounds like a real urgent alarm, and a long low beep followed by a high beep typically marks a different diagnostic event such as startup or reset rather than a test failure.
