Smoke alarms are essential safety devices that can help to save lives in the event of a fire. They work by detecting smoke and sounding an alarm to alert occupants to evacuate the building. It is important to check your smoke alarms regularly to make sure that they are working properly.
There are a few simple steps you can follow to check your smoke alarms. First, check to make sure that the alarm is turned on. Then, press the test button on the alarm. The alarm should sound a loud, piercing sound. If the alarm does not sound, or if it sounds weak or intermittent, it may need to be replaced.
