What is the replacement or testing interval for quick response sprinklers?

Quick response sprinklers are designed to activate more quickly than standard sprinklers, providing an earlier response to heat and potential fire situations. The replacement or testing interval for these sprinklers is set to ensure their functionality and reliability over time. The industry standard recognizes that quick response sprinklers should be tested or replaced every 20 years to ensure they remain effective and operate correctly when needed.

This 20-year interval is based on the understanding of the materials and mechanisms used in the design of quick response sprinklers, which may degrade or become less reliable over an extended period. Regular testing and potential replacement help to avoid failures in critical situations, thereby enhancing the safety and effectiveness of fire protection systems.
