Which statement about alarm systems is true?

Regular testing is essential for alarm systems to ensure they are functioning properly. This involves checking the components such as sensors, alarms, and control panels to verify that they respond as expected in the event of an emergency. Routine tests and maintenance can reveal issues like low battery levels, outdated software, or malfunctioning sensors, which, if left unchecked, could compromise the system's effectiveness when needed most. Staying proactive with testing helps to maintain security and safety, making it a critical aspect of alarm management.
