If a fire alarm system serves more than one building, each building shall be indicated a separate zone of origin.

• A. False
• B. Not Applicable
• C. Affirmative
• D. True

Answer: (D)

Zones indicate exactly where an alarm condition originated. When a fire alarm system serves more than one building, giving each building its own zone of origin lets responders know precisely which building is affected. This clarity speeds and targets the response, supports appropriate occupant notification and actions (like evacuation or elevator recall), and helps the control panel direct information to the right building and staff. You can still have multiple zones within a building for different floors or areas, but for a system that spans multiple buildings, one zone per building is the proper setup to avoid cross-building confusion. So the statement is true.
