Manual actuators shall be located between ten and twenty feet from the system.

• A. 5 to 10 feet
• B. 10 to 20 feet
• C. 20 to 30 feet
• D. 0 to 5 feet

Answer: (B)

Manual actuators are placed at a practical distance to balance quick access with safety. Positioning them between ten and twenty feet from the system makes them reachable quickly by people in typical work areas without placing them in the most hazardous zone or directly in the line of heat or flames. If the devices were placed much closer, they could be more prone to accidental activation or damage from cooking heat and splatter. If they were placed farther away, it would take longer for someone to reach the actuator, delaying manual activation and potentially reducing the effectiveness of the extinguishing action. So the ten-to-twenty-foot range is chosen to optimize both accessibility and safety.
