What is the maximum height above floor level for the operable part of a manual fire alarm box?

• A. 44 inches
• B. 40 inches
• C. 50 inches
• D. 48 inches

Answer: (D)

Easy and quick access to the alarm is the goal, so the operable part of a manual fire alarm box must be placed where most occupants can reach it without effort. That’s why it’s limited to a maximum height of 48 inches above the finished floor. This height is chosen to be reachable for standing adults and for people who are seated or in wheelchairs, ensuring a fast, hands-on activation in an emergency. Heights higher than that would hinder anyone trying to reach it quickly, while lower heights are still usable but don’t represent the maximum allowed reach, and a height of 50 inches would be out of compliance.
