According to NFPA 72, where should pull stations be mounted on the wall in terms of vertical height from the floor?

• A. On the wall with a height range of 3.5 to 4.5 feet from the floor
• B. Mounted on the ceiling near eye level
• C. On a freestanding pedestal at waist height
• D. On the door frame about 2 feet from the floor

Answer: (A)

Pull stations are designed to be easily reachable in an emergency, so they’re mounted on the wall at a standardized height that most people can reach without climbing or bending awkwardly. NFPA 72 specifies that the activator should be installed so the centerline of the device is about 48 inches above the finished floor, with a practical tolerance that places the usable height roughly in the range of 3.5 to 4.5 feet. This range accommodates standing adults and those seated or shorter, while keeping the device clear of doors and other obstructions.

Choosing a ceiling-mounted, freestanding pedestal, or door-frame placement would either make the device hard to reach or not align with the standard wall-mount practice mandated by NFPA 72. Hence, the correct mounting height is on the wall at roughly 3.5 to 4.5 feet from the floor.
