How often must smoke detectors be tested for smoke entry?

The requirement for smoke detectors to be tested for smoke entry at least once a year is grounded in fire safety regulations and best practices. This annual testing ensures that the smoke detectors are functioning correctly and can detect smoke effectively in case of a fire. Regular testing helps identify any issues such as battery failure or sensor malfunction that could prevent the detectors from alerting occupants in an emergency.

While more frequent tests, such as monthly, can further enhance safety and ensure reliability, the minimum standard set by codes and regulations is an annual test. This practice is crucial for maintaining a safe environment, especially in buildings where rapid fire detection is essential for occupant safety and compliance with local fire safety laws.
