Systems that provide for a partial evacuation or relocation of occupants must be what?

• A. survivable
• B. non-survivable
• C. redundant
• D. optional

Answer: (A)

Partial evacuation relies on keeping occupants safe even as a fire develops, so the system must be survivable. Survivable means it continues to operate under fire conditions—power loss, heat, and smoke—and still perform essential life-safety functions like clear, reliable notification and guidance to safe areas or exits. This resilience allows people who can’t evacuate all at once to relocate or wait for further instructions without the system failing. Non-survivable would defeat the purpose of protecting occupants in a real event, while redundancy helps support survivability but isn’t the exact requirement, and optional implies it isn’t needed for life safety.
