What is the maximum travel distance between fire alarm pull boxes on a floor?

• A. 100 feet
• B. 150 feet
• C. 200 feet
• D. 250 feet

Answer: (C)

The distance rule for manual fire alarm devices is about making sure an alarm can be triggered quickly from anywhere on a floor. The maximum travel distance between fire alarm pull boxes on a floor is 200 feet. This means you place pull boxes so that no point on the floor is more than 200 feet away from the nearest box, helping ensure timely activation of the alarm, faster notification, and safer evacuation.

In practice, pull boxes are spaced at regular intervals along corridors and open areas to meet this limit, typically at corridor intersections or near egress paths. Choosing a shorter distance would mean more devices and higher cost, while a longer distance could delay alarm activation and compromise safety.
