What must be monitored quarterly in sprinkler systems in compliance with NFPA 25?

Monitoring alarm devices and supervisory alerts quarterly in sprinkler systems is essential for ensuring that these systems are functioning correctly and can activate effectively in the event of a fire. NFPA 25 outlines the requirements for the maintenance and testing of water-based fire protection systems. Specifically, alarm devices, which indicate the operational status of the sprinkler system, must be tested regularly to confirm that they are not only in working order but also properly notifying the proper authorities or monitoring services in case of an emergency.

Regular monitoring of alarm devices helps in early detection of faults or malfunctions, which could prevent the sprinkler system from functioning as intended when it is needed the most. This proactive approach to fire safety aligns with the NFPA's goal of ensuring that fire protection systems are reliable and effective.

In contrast, while water storage levels and inspection of fire extinguishers are vital components of a comprehensive fire safety plan, they are not specifically required on a quarterly basis as part of NFPA 25's guidelines for sprinkler systems. Fire fighting training records are crucial for ensuring personnel are prepared, but they do not pertain to the operational status of the sprinkler systems themselves as outlined in NFPA 25.
