How often should fire alarm systems be tested in commercial buildings?

Fire alarm systems should be tested at least once a year, or according to local regulations, to ensure their proper functioning and compliance with safety standards. Regular testing is crucial because it helps in identifying any potential issues that could prevent the alarm from performing effectively in the event of a fire. Local regulations often have specific requirements that may dictate more frequent testing based on various factors, such as the type of building or its usage.

Adhering to this annual testing schedule not only enhances safety by ensuring that the system is operational but also demonstrates responsibility on the part of building management. Regular maintenance and testing can help avert tragedies and financial loss that might occur if a fire alarm fails when needed.

In contrast, testing fire alarm systems only when there is a complaint is insufficient and puts occupants at risk. Similarly, testing every five years is generally not frequent enough to maintain effectiveness, while conducting tests quarterly may exceed the basic requirements in some jurisdictions but could still be viable if stipulated by local laws.
