What is a common maintenance task for fire alarm systems?

Replacing batteries is indeed a common maintenance task for fire alarm systems. Fire alarm systems rely on batteries to ensure they remain operational during power outages or emergencies. Regularly checking and replacing these batteries is essential for maintaining the reliability of the system. A failed battery can lead to a malfunctioning alarm, which could jeopardize safety by failing to alert occupants in the event of a fire.

While other tasks, such as repainting detectors or disconnecting unused wires, may be relevant in certain circumstances, they are not standard maintenance practices designed to ensure the fire alarm system functions properly. Resetting alarms weekly might be useful in specific scenarios, but it is not a common practice for regular maintenance. Maintaining the integrity and reliability of battery power is crucial for the overall effectiveness of the fire alarm system.
