Manual fire alarm boxes shall be mounted within a height range of 3 1/2 feet to 6 feet.

• A. True
• B. Not specified
• C. Only in new construction
• D. False

Answer: (D)

Manual pull stations are placed where occupants can reach them quickly in an emergency, so their mounting height is set to be easily reachable by most people. Codes typically require a range around 4 feet to 6 feet above the finished floor, ensuring the device is usable by standing adults and accessible to those with limited reach. The stated range of 3 1/2 feet to 6 feet is not correct because 3 1/2 feet (42 inches) is below the commonly required minimum. That’s why the assertion is false—the lower limit should be higher than 3 1/2 feet.
