Sprinklers installed prior to which year shall be replaced?

Sprinklers installed prior to 1920 are typically considered outdated and must be replaced due to their potential limitations in performance and compliance with modern fire protection standards. This year is significant because it marks a turning point in sprinkler technology, with advancements leading to improved reliability and efficacy in fire suppression. The standards for fire protection have evolved considerably since the early 20th century, and systems installed in that earlier timeframe may not meet current safety requirements or could be prone to malfunction. Replacing older sprinkler systems ensures that facilities adhere to the latest codes and standards, enhancing overall fire safety. Understanding this requirement is crucial for maintaining the effectiveness of fire protection systems.
