Fusible links and automatic sprinkler heads shall be replaced how often?

Fusible links and automatic sprinkler heads shall be replaced how often?

• A. Biennially
• B. Monthly
• C. Annually
• D. Every five years

Answer: (C)

Regular maintenance of automatic fire protection components emphasizes replacing heat‑sensitive parts that can age or suffer from exposure and handling. Fusible links are designed to melt at a specific temperature to release the water supply; over time they can corrode, seize, or deteriorate, so replacing them on a yearly basis helps ensure the release mechanism will operate reliably when a fire occurs. Automatic sprinkler heads also rely on precise, heat‑activated mechanisms; bulbs and seals can degrade, become obstructed, or suffer minor damage, which increases the risk of a failed discharge or leaks if not refreshed regularly. A yearly replacement schedule provides a practical safeguard against undetected degradation, whereas monthly would be excessive for these components, and longer intervals could allow unseen failures to develop. If a head has discharged or shows damage, it should be replaced immediately, outside of the routine interval.
