How often should fusible links be changed?

Fusible links play a critical role in the fire suppression system of commercial cooking operations as they are designed to melt at a specific temperature, enabling the fire suppression system to activate in response to heat. According to the NFPA 96 Standard, it is advised that these links be changed semi-annually to ensure they function effectively when needed. This maintenance frequency helps mitigate the risk of malfunction and ensures that the system remains reliable in case of a fire event. Regular replacement is essential because environmental factors, like grease buildup or exposure to heat, can impact the integrity of the fusible links over time. This level of proactive maintenance is part of best practices for ensuring the safety of commercial cooking operations.
