How often should smoke detectors be tested for sensitivity?

Smoke detectors should be tested for sensitivity every year to ensure they are functioning properly and can effectively detect smoke and alert occupants in case of a fire. Regular annual testing is crucial because it allows for the identification of any issues that might have developed over time, such as battery failure or mechanical malfunctions.

Testing annually aligns with many fire safety regulations and recommendations from authorities such as the National Fire Protection Association (NFPA), which emphasizes the importance of maintaining reliable smoke detection systems in residential and commercial settings. While it's also essential to check batteries regularly, typically suggested to be done twice a year, comprehensive sensitivity testing should be conducted annually to guarantee optimal performance.
