Which statement about smoke detector sensitivity checks is true?

Smoke detector sensitivity checks are essential for ensuring the reliable operation of fire alarm systems. Performing these checks every year allows for the assessment of the detector's responsiveness to smoke, which can deteriorate over time due to factors such as dust build-up, environmental conditions, or aging components. Regular annual testing helps to ensure that the detectors will activate appropriately during a fire, thereby enhancing the overall safety of the building. This frequency aligns with recommendations from fire safety standards and manufacturers to maintain optimal performance and compliance with regulations.

While some may consider sensitivity checks to be optional or unnecessary, neglecting them can lead to false alarms or failures to detect smoke, which significantly undermines the purpose of having smoke detectors installed. Regular checks are a proactive approach to fire safety.
