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

• A. Six inches
• B. Eight inches
• C. Twelve inches
• D. Twenty-four inches

Answer: (C)

Fusible links are heat-activated devices that trigger the kitchen fire suppression system when they reach a specific temperature. Placing them a defined distance in front of the appliance keeps them within the heat plume of cooking equipment while protecting them from direct splatter or damage, allowing reliable activation when a fire occurs. The standard distance is twelve inches in front of the referenced item, which provides a balance between timely response and physical protection. If the link is too close, it can be damaged or exposed to excessive heat; if it’s too far, the system may not activate quickly enough to suppress the fire.
