Which component is replaced annually according to the guidelines?

• A. Fusible links and automatic sprinkler heads
• B. Vent hood filters
• C. Sodium Bicarbonate containers
• D. Detectors

Answer: (A)

In a kitchen hood fire suppression system, the release mechanism relies on heat-activated parts that must stay reliable. Fusible links melt at a specific temperature to trigger the extinguishing agent, and the automatic sprinkler heads are part of that activation path. Over time these components can degrade from heat exposure, corrosion, or wear, which can compromise how quickly and effectively the system responds in a fire. Replacing these parts annually is a preventive maintenance practice to ensure the system will activate promptly and correctly when needed.

Other items in the system have different maintenance needs. Vent hood filters must be replaced based on grease buildup and cleaning needs, not on a strict annual schedule. Sodium bicarbonate containers and detectors have their own service intervals and are not generally replaced every year.
