How often should the supervisory functions of a dry pipe sprinkler system be tested?

The supervisory functions of a dry pipe sprinkler system should be tested annually to ensure that the system is functioning correctly and that all components are operational. This testing interval is established to maintain reliability and ensure compliance with relevant codes and standards, such as those set by the National Fire Protection Association (NFPA).

Annual testing helps to assess critical components of the dry pipe system, including the alarm devices, valves, and air pressure monitoring. This schedule allows for proactive maintenance, helping to identify any issues before they become serious problems when the system is needed in an emergency.

Regular annual checks also allow for the documentation of the system's performance over time, which can be vital for inspections and regulatory compliance. Additionally, by adhering to this testing schedule, property owners can better ensure the safety of the building's occupants and protect the facility from potential fire risks.
