In NFPA 72, survivability levels are defined in which chapter?

• A. Chapter 10
• B. Chapter 11
• C. Chapter 12
• D. Chapter 13

Answer: (C)

Survivability levels describe how much of the fire alarm system must stay operational under adverse conditions, ensuring life-safety signaling continues even if parts of the system or power are compromised. In NFPA 72, these performance criteria are defined in Chapter 12, which groups requirements for maintaining operation during fault conditions and outages. This placement emphasizes survivability as a specific performance topic, separate from installation or testing details found in other chapters.
