In a system serving multiple buildings, which statement about the origin zones is correct?

• A. The zones may merge into a single zone
• B. Zones are only needed for large campuses
• C. Each building's origin must be indicated as a separate zone
• D. Origin zones are determined by fire code only

Answer: (C)

In a fire alarm system that serves multiple buildings, the origin zones tell you exactly which building triggered the alarm. That precision is crucial for responders to direct their approach and investigations quickly. Because of this, each building’s origin should be indicated as a separate zone—the best way to provide clear, localized information at the control panel and annunciators. If zones from different buildings were merged into one, the system could point to a generic area rather than a specific building, delaying response and making it harder to pinpoint the source. Zones aren’t only for large campuses; even a small group of buildings benefits from distinct zones to ensure fast, accurate identification of where an alarm originated. Fire code requires proper zoning and clear annunciation, but the actual setup—assigning a separate zone for each building—is a design choice that reflects the physical layout and supports effective response and maintenance, not something dictated by code alone.
