How often should alarms be tested according to standard practices?

Testing alarms quarterly aligns with common fire safety practices and recommendations to ensure that life safety systems function properly. This frequency allows for timely identification of any malfunctions or issues that could hinder the alarm's effectiveness in an emergency situation.

Regular testing helps ensure that all components of the alarm system, such as sensors and backup batteries, are in optimal working condition. Quarterly testing is also often reinforced by various fire safety codes and standards which emphasize the importance of proactive maintenance in promoting safety.

While other options might suggest valid intervals for specific maintenance tasks or less critical systems, quarterly testing strikes a balance between diligence and practicality, making it the safest and most recommended choice for ensuring reliable alarm performance.
