How frequently should alarms connected to water-based fire protection systems be tested?

Testing alarms connected to water-based fire protection systems is essential to ensure that they function correctly when needed. The National Fire Protection Association (NFPA) recommends that these alarms be tested at least annually. This annual testing helps to verify that the alarm's performance meets the standards required for reliable operation in emergencies.

Regular testing is critical because it identifies potential issues that could impair the alarm's function, such as mechanical failures or system malfunctions. By adhering to this annual testing requirement, facility managers can ensure that their fire protection systems remain compliant with safety regulations and are dependable in case of a fire incident.

While more frequent testing, such as monthly or quarterly, could be beneficial in certain situations, NFPA 25 specifically mandates the annual interval as the standard for alarm testing in water-based fire protection systems. This balance of sufficient testing frequency with practical resource management underscores the rationale behind the annual requirement.
