Which factor concerning testing inspections is governed by NFPA 72?

The method and frequency of testing inspections are governed by NFPA 72, which is the National Fire Alarm and Signaling Code. This code outlines the minimum requirements for the application, installation, location, performance, inspection, testing, and maintenance of fire alarm systems. Specifically, NFPA 72 addresses how often testing should occur and the procedures that should be followed to ensure that fire alarm systems are effectively monitored for reliability and performance.

By establishing consistent methods and frequencies for inspections and tests, NFPA 72 ensures that fire alarm systems remain functional and compliant with safety standards, ultimately contributing to enhanced fire safety in buildings. This consistency is vital for maintaining the integrity and operational readiness of fire alarm systems, indicating that the code treats this aspect with particular importance for effective fire protection.
