After passing the initial testing, when should dry-type sprinklers next be tested?

Dry-type sprinklers are a critical component in fire protection systems, particularly in environments where the presence of water could cause damage. After the initial testing, it is required that these sprinklers should undergo subsequent testing every five years. This interval is established to ensure that the sprinklers remain functional and reliable over time, addressing concerns related to corrosion, mechanical failure, or other factors that could compromise their effectiveness in an emergency situation.

Regular testing every five years aligns with industry standards and codes designed to maintain safety standards within fire protection systems. It provides a structured approach to assessing the condition of the sprinklers and helps in identifying any required maintenance or replacements before a fire incident occurs.
