What is the minimum number of fire alarm pull boxes required per floor?

• A. 0
• B. 1
• C. 2
• D. 3

Answer: (B)

The basic idea is that every floor needs at least one readily accessible manual way to initiate the fire alarm. Having one pull box on each floor ensures occupants can quickly alert others and start evacuation without having to go to another level. More than one may be used in very large floors or along long corridors for faster coverage, but the minimum requirement is one per floor. Zero on a floor would leave that level without a manual alert point, which isn’t acceptable for timely evacuation.
