According to NFPA 72, which statement is true regarding zoning?

• A. Each floor must be zoned as one single zone
• B. Only the entire building must be zoned
• C. Each floor of the building must be zoned individually
• D. Zones are optional and not required

Answer: (C)

Zoning groups initiating devices and signaling appliances so the fire alarm system can indicate exactly where an alarm originated and control actions by area. In practice, NFPA 72 sections that address zoning are written with the idea that a multi-story building should have separate zones for each floor. This lets the panel display a specific floor when an alarm occurs, and it allows you to tailor notification and control on that floor without automatically disturbing every other level. Because of that, the statement that each floor of the building must be zoned individually best reflects how zoning is used to locate and manage alarms in a multi-floor structure. Zones are not optional, and using a single zone for the entire building would hinder pinpointing the source and coordinating response. It’s common to see additional subdivisions for other areas (like mechanical rooms or elevators), but the floor-by-floor zoning principle is the key standard concept.
