What additional testing can be done during the inspection of a smoke detector?

Functional tests with smoke are a critical part of the inspection process for smoke detectors. This type of testing involves using a controlled smoke source to ensure that the detector responds appropriately to smoke presence, simulating real-world conditions. It's essential because it verifies not only that the detector is installed correctly but also that it functions as intended, providing an accurate safety measure in the event of a fire. This hands-on testing confirms the sensitivity and reliability of the smoke detector under practical circumstances, rather than just checking the physical condition or installation.

Other options do not encompass the full testing capabilities needed during an inspection. Visual inspection only assesses the physical integrity of the detector but does not confirm operational performance. Battery replacement alone does not ensure the detector is functioning correctly; a detector can have a new battery and still fail to operate in a fire situation. Checking the installation location is necessary for proper smoke detection coverage but does not test the detector's functional capabilities.
