A building inspector is performing a final inspection of a new four-story mixed-use building with Group R-2 apartments above Group A-2 retail on the ground floor. The building incorporates a fire command center. Which of the following is NOT a required feature or equipment for a fire command center in this building, according to IBC?
- AControls for unlocking stairwell doors
- BFire department lock box (Knox Box)
- CFire alarm control unit
- DEmergency voice/alarm communication system control unit
Show answer & explanationAnswer & explanation
Correct answer: B. Fire department lock box (Knox Box)
According to IBC Section 911.1 and 911.2, a fire command center is a required area in certain buildings (such as high-rise buildings or buildings with complex fire protection systems) and must contain specific equipment. While a fire alarm control unit, emergency voice/alarm communication system control unit, and controls for unlocking stairwell doors are explicitly listed as required components (IBC 911.1), a fire department lock box (Knox Box) is typically located on the exterior of the building, near the main entrance, to provide fire department access to keys, not inside the fire command center itself.
Why the other options are wrong
- A. Controls for unlocking stairwell doors are specifically listed as required equipment within the fire command center (IBC 911.1).
- C. The fire alarm control unit is a core component required within the fire command center (IBC 911.1).
- D. The emergency voice/alarm communication system control unit is a required component of the fire command center (IBC 911.1).
