According to regulations, how should inspectors test accessible smoke alarms?

  1. By manual testing using an approved method

  2. By visual inspection only

  3. By using water

  4. By overloading the circuit

The correct answer is: By manual testing using an approved method

The proper method for testing accessible smoke alarms is through manual testing using an approved method. This typically involves pressing the test button on the smoke alarm to ensure it functions correctly and emits an audible alarm sound. This is a vital step in verifying that the smoke alarm is operational and ready to alert occupants in the event of smoke or fire. Visual inspection alone does not ensure that the smoke alarm is functioning properly; it may appear intact but could still be non-operational due to various factors, such as battery failure. Using water to test smoke alarms is not appropriate as it could damage the unit and render it inoperable. Similarly, overloading the circuit can present safety hazards, and it does not provide a measure of the smoke alarm's functionality. Therefore, manual testing aligns with regulations and best practices in home inspections, ensuring that safety devices are fully operational to protect residents.
