How are fire alarm systems in high-rise buildings often programmed to alert occupants?

• A. Alert Only the Floor of Origin
• B. Notify Central Dispatch Only
• C. Alert Floors Immediately Below and Above
• D. Sound External Alarms Only

Answer: (C)

In high-rise buildings, alarm notification is often organized in zones and done progressively rather than system-wide. The goal is to alert only the areas most at risk so occupants can evacuate safely without causing unnecessary panic or crowding on floors far from the danger. By signaling the floors immediately below and above the fire floor, the system targets those most likely to be affected by smoke or heat and those who use the same stairwells for egress, enabling a safer, more controlled evacuation. Alerting solely the floor of origin or relying on central dispatch to handle notifications for occupants doesn't provide timely, on-site guidance to people who need to evacuate. Sounding only external alarms wouldn’t help people inside the building know what’s happening. Limiting alerts to the adjacent floors balances prompt warning with orderly egress and is a common practice in high-rise fire alarm strategies.
