Where should the bottom of a fire alarm pull box be installed from the floor?

• A. 2 feet from the floor
• B. 3.5 to 4.5 feet from the floor
• C. 5 to 6 feet from the floor
• D. 6 to 7 feet from the floor

Answer: (B)

Mounting height for manual fire alarm pull boxes is all about accessibility and quick, reliable access. Placing the bottom of the pull box about 3.5 to 4.5 feet above the floor keeps the activation point within a practical reach range for most people, including those in wheelchairs, and aligns with accessibility guidelines that require operable parts to be reachable without needing to stretch or stand on tiptoe. If it’s mounted too low (around 2 feet), it can be more prone to accidental activation and may not provide consistent clearance around the box. If it’s mounted too high (5–6 feet or higher), people with limited reach may not be able to operate it promptly. So, 3.5 to 4.5 feet is the height that best balances ease of use, safety, and code compliance.
