According the NFPA a 'zone' is a defined area within the?

• A. Protected premises
• B. Public premises
• C. Exterior area
• D. Occupied building

Answer: (A)

Zones organize a fire alarm system by dividing the space under protection into defined areas so responders can locate the origin quickly. In NFPA 72, a zone is a defined area within the protected premises where initiation devices and indicators are grouped and feed into a common zone circuit on the control panel. This lets the panel report the general location of an alarm or fault inside the building, guiding response and enabling targeted maintenance. Outside the protected premises, such as public or exterior areas, aren’t used for the zone concept under NFPA 72, and referring to an “occupied building” is less precise than the formal term “protected premises.”
