Smoke Detector manufacturers recommend replacing your smoke detectors every 10 years as the sensors loose sensitivity.
The test button on the detector only confirms the battery and alerting system still work, not that the smoke sensor actually works.
It is recommended smoke detectors be placed on every floor and every bedroom. If the home has hydrocarbon fueled equipment (natural gas, propane, heating oil) carbon monoxide detectors should also be installed.
