NFPA 72 sets a maximum travel distance to the nearest fire alarm box from any point as which of the following?

• A. 50 feet
• B. 100 feet
• C. 150 feet
• D. 200 feet

Answer: (B)

The essential idea is that manual fire alarm devices must be reachable quickly from any point in the building to ensure prompt notification. NFPA 72 sets a maximum travel distance to the nearest fire alarm box so occupants aren’t far from a pull station and can initiate the alarm without delay. That limit is 100 feet of travel distance along the normal path of egress. In practice, you’d layout rooms and corridors so no point is more than 100 feet away from a manual alarm box; if a design would exceed this, additional pull stations or repositioning are needed to meet the requirement. Distances like 150 or 200 feet would be too long for timely notification, while 50 feet is easily within the limit.
