In multi-building fire alarm installations, each building must be assigned its own origin zone.

• A. True
• B. False
• C. Only for certain building types
• D. Not specified

Answer: (A)

In a multi-building fire alarm system, the key idea is to localize where an alarm begins so responders know exactly which part of the campus is affected. Assigning an origin zone to each building achieves this by tying the initiating devices and the initial alarm signal to a specific building. This separation lets the control panel report and display the exact building that triggered the alarm, supports building-specific evacuation and response, and keeps events from one building from being ambiguously linked to another. Because of this need for precise localization and independent operation, the requirement is to give each building its own origin zone. The other options would either blur the source of the alarm, apply only to certain building types, or lack specification, which would undermine clear detection and response.
