smoke alarm

A good smoke alarm is the first line of defense against fires. One should be installed in every room and hallway for maximum effect. Alarms should also be checked on regular basis to make sure they will work in the event of an emergency. First batteries of each fire alarm in a home or work place should be checked to see if the battery is still working. Most alarms have a test light that helps with this function. Second, the alarm should be tested to see if sounds properly at the hint of heat or smoke.
