Which statement best describes the signaling requirements for hearing-impaired occupants?

• A. Visible strobes, synchronized signaling, and accessible egress information
• B. Only audible alarms
• C. Verbal announcements only
• D. Visual-only alerts

Answer: (A)

For hearing-impaired occupants, the warning system must deliver information they can actually perceive and act on, not just rely on sound. Visible strobes provide the immediate visual alert, so someone who can’t hear the alarm still knows there’s an emergency. Synchronizing the signaling ensures all parts of the building flash together, creating a clear, unified cue rather than a confusing mix of signals that might be missed or misinterpreted. Accessible egress information is essential to guide people to safety, offering clear instructions and paths that don’t depend on hearing to convey direction.

That’s why combining visible strobes, synchronized signaling, and accessible egress information best meets the needs of hearing-impaired occupants. Relying on audible alarms alone excludes those with hearing loss, verbal announcements depend on hearing, and visual-only alerts without proper synchronization and guidance may leave occupants uncertain about what to do next.
