In a combination system with a single display, a second display for the fire alarm portion is required when what condition is met?

• A. The AHJ determines the non-fire alarm information displayed is excessive
• B. The building has mixed occupancy
• C. The system is not silent
• D. The fire alarm must be independent

Answer: (A)

When a single display is used for a combination fire/other system, keeping fire alarm information clear is essential. A second display for the fire alarm portion is required when the Authority Having Jurisdiction determines that the non-fire alarm information shown on the same display is excessive. This ensures that fire alarm status and alerts remain easily readable and quickly understood, without being overwhelmed by other data. The other scenarios listed don’t directly address the need to separate the fire alarm information; they relate to different considerations and do not mandate a separate fire alarm display itself.
