Smoke alarms should be tested:

Smoke alarms should indeed be tested according to the manufacturer's instructions because these guidelines provide specific recommendations based on the technology and design of each particular device. Different smoke alarms may have varying requirements for testing frequency, depending on factors such as the type of alarm (ionization or photoelectric), the battery type, or whether it is interconnected with other alarms. Adhering to the manufacturer's instructions ensures that the device functions properly and maximizes safety in a fire situation.

While annual testing is a common recommendation and may apply to many models, it is not universally applicable to all smoke alarms. Some manufacturers may suggest a different frequency or additional maintenance checks. Regular testing is important, but following the precise instructions provided ensures that each specific unit is maintained according to its designed performance criteria. This is critical for ensuring reliability in emergency situations.
