If a building has a blend of different types of sprinklers including both dry-type and quick response, which type's intervals for testing would generally be shorter?

Quick response sprinklers are designed to activate more quickly than standard sprinklers, providing rapid suppression of a fire. As a result of their enhanced performance capabilities, the testing intervals for quick response sprinklers are often set to be shorter than those for dry-type sprinklers. This is primarily due to their critical role in life safety and property protection within a building.

Maintaining these fixtures at optimal performance is essential, especially since quick response sprinklers can significantly reduce the amount of heat and smoke generated in the early stages of a fire. Regular testing helps ensure that they remain reliable and effective.

Dry-type sprinklers, on the other hand, are generally used in areas prone to freezing and may have different testing requirements due to their construction and function. This distinction in functionality and purpose leads to differing testing intervals, emphasizing the need for more frequent checks on quick response models to safeguard against potential fire hazards.
