What are the mounting requirements for fire alarm pull boxes?

• A. Bottom not less than 3.5 feet from the floor and not more than 4.5 feet; travel distance not to exceed 200 feet; one per floor minimum.
• B. Mounted at eye level; travel distance not to exceed 200 feet; two per floor minimum.
• C. Mounted on the ceiling; travel distance not to exceed 50 feet; one per floor minimum.
• D. Base at floor level; no travel distance limit; one per building.

Answer: (A)

The key idea is ensuring manual fire alarm activation is easily reachable and available throughout the building so occupants can trigger the system quickly in an emergency. Pull boxes are placed so someone can reach them without obstacles, and there’s enough coverage on each floor to avoid long trips to activate the alarm. Mounting them with the bottom edge between 3.5 and 4.5 feet above the finished floor makes them accessible to most people, including those in wheelchairs, while keeping them out of the way of typical foot traffic and potential water or debris on the floor. Limiting travel distance to 200 feet ensures that from any point on a floor, a pull station is within a reasonable distance, reducing delay in alerting building occupants. Having at least one pull box on every floor guarantees there’s an activation point close to stairways and exits, which is crucial in multi-story buildings. Other options deviate from these standards: placing them at eye level or on the ceiling isn’t consistent with the established mounting height guidelines; mounting with the base at floor level makes them hard to reach safely; a travel distance of 50 feet is not in line with typical code requirements; and requiring two pull boxes per floor or one per building misses the floor-by-floor coverage needed for a prompt, universal manual alarm activation.
