A readily accessible means for manual activation shall be located between __ and __ above the floor, be accessible in the event of a fire, be located in a path of egress, and clearly identify the hazard protected.

• A. 24-30 in
• B. 60-72 in
• C. 12-18 in
• D. 42-48 in

Answer: (D)

A manually operated activation device for a fire protection system should be mounted at a height that combines speed, accessibility, and visibility. Placing it between 42 and 48 inches above the floor achieves this: it is high enough to avoid being easily knocked over or blocked by objects on the floor, yet low enough to be reachable quickly by most people in an emergency. Keeping it in the path of egress ensures it stays reachable during an evacuation, even if other routes become obstructed, and helps prevent confusion about where to activate the system. Clear identification of the hazard protected, such as “Grease Fire—Kitchen Hood,” makes it obvious what protection is being engaged when the device is used. Other heights would be less practical—too low can be blocked or accidentally triggered; too high can be difficult or impossible to reach during a fire.
