Which describes Alert Tone 2 and its sound?

• A. Emergency five-second-high low tone (mayday, abandon structure)
• B. Continuous siren
• C. Five long tones
• D. Voice alert with instructions

Answer: (A)

Alert tones use quick, distinctive sounds so responders can act immediately. Alert Tone 2 is the short emergency signal that lasts five seconds and alternates between high and low tones, signaling a mayday or the need to abandon the structure. It’s designed to be unmistakable and prompt immediate protective action. The other options don’t fit because a continuous siren isn’t a discrete cue for a specific action; five long tones don’t match the five-second high-low pattern; and a voice alert with instructions is spoken, not a tonal cue.
