Fusible links shall be located at what distance in front of the item?

• A. Twelve inches
• B. Six inches
• C. Two inches
• D. Thirty inches

Answer: (A)

Fusible links are heat-sensitive devices that trigger the kitchen fire suppression system when the appliance overheats. Placing the link about twelve inches in front of the cooking unit puts it in the effective heat plume so it responds promptly to rising temperatures, without being so close that it’s easily damaged by splatter, grease, or direct contact. If it’s placed too near, it can fail due to physical damage or contamination; if it’s too far, the heat doesn’t reach the link quickly enough to activate the system in time. Twelve inches strikes a practical balance and aligns with standard installation practices for kitchen hood suppression systems.
