How often must Class "B" and "R-1" fire alarm systems be physically tested?

Class "B" and "R-1" fire alarm systems must be physically tested at reasonable intervals to ensure they remain functional and reliable in the event of an emergency. This requirement recognizes the dynamic nature of building occupancy and usage, which can affect the performance and need for testing of fire alarm systems.

Testing at reasonable intervals allows for flexibility in the schedule while still prioritizing safety and compliance with local codes and regulations. It emphasizes the importance of maintaining these systems regularly, rather than adhering strictly to a monthly, annual, or bi-annual schedule, which may not adequately address specific building needs or conditions that could impact system effectiveness.

By requiring testing at reasonable intervals, it ensures that the fire alarm systems are appropriately assessed based on usage, potential wear and tear, and any modifications to the building or its occupancy that could require more frequent checks. This approach provides a balance between compliance and practicality, addressing the real-world demands of maintaining life safety systems.
