Occupancy-based code considerations vary for educational facilities, healthcare, and high-rise buildings. Which statement is correct?

• A. Education facilities require nurse-call integration.
• B. Healthcare facilities require speech/VOX messaging.
• C. High-rise buildings ignore floor signaling.
• D. Education facilities commonly use speech/VOX messaging; healthcare facilities commonly require nurse-call integration; high-rise buildings commonly implement floor-by-floor signaling.

Answer: (D)

Occupancy-based signaling is about matching alarm and communication strategies to how people use and move through a space. Educational facilities rely on speech/VOX messaging to quickly convey instructions to a large, mixed-age audience and to avoid confusion with text-only cues. Healthcare facilities depend on nurse-call integration so staff can be alerted and respond to patients efficiently during emergencies. High-rise buildings benefit from floor-by-floor signaling to guide occupants as they evacuate across many levels and to coordinate stairwell use. This combination—speech/VOX in schools, nurse-call in healthcare, and floor-by-floor signaling in high-rises—fits the distinct needs of each occupancy, making it the best overall statement. The other options misstate typical requirements or ignore how signaling is used in tall buildings.
