Which system ensures that the alarm devices operate correctly?

The correct choice highlights the importance of regular inspection and maintenance of alarm devices within a fire alarm system. Fire alarms are critical safety components that must function effectively to alert occupants in the event of a fire. Routine inspection involves checking each device, including smoke detectors, heat detectors, and alarm signals, to ensure they are working as intended without any faults.

Additionally, maintenance tasks such as cleaning, replacing batteries, and updating software contribute to the reliability of the system. Without these regular checks, the risk of alarm failure increases, which can have dire consequences for safety and compliance with fire codes. Therefore, implementing a structured schedule for inspection and maintenance is essential for confirming that the alarm devices operate correctly, providing peace of mind and ensuring safety for building occupants.

In contrast, building occupancy evaluations primarily focus on assessing the people present in a space rather than ensuring the functionality of fire alarms. Daily fire drills are valuable for training occupants on evacuation procedures but do not directly ensure the operational status of the alarm devices. Noise level assessments are unrelated to fire alarm functionality, as they measure sound levels rather than the operational readiness of safety equipment.
