True or False: If two buildings share a fire alarm system, they must be assigned to the same zone of origin.

• A. True
• B. False
• C. Not specified
• D. Depends on system

Answer: (B)

Zones are used to localize where an alarm originated and to make response and maintenance easier. If two buildings share a single fire alarm system, the installer can define separate zones for each building, or even group them into a larger zone if that fits the layout. There’s no rule that forces both buildings to be in the same zone of origin; zone boundaries depend on wiring, detector placement, and how the panel is configured. Having distinct zones helps responders know exactly which building triggered the alarm and aids in fault isolation. So, it isn’t required that the two buildings share the same zone.
