Clean alarms with a vacuum cleaner. Do not remove the cover to clean dust and spider webs from alarms.
Install fresh batteries at least once a year. A good way to remember is to change batteries when the clocks are changed in the spring and fall.
Make sure everyone in your household is familiar with the alarm’s sound. Plan an escape route and a meeting place.
Make sure there is a smoke alarm on every level of your home including the basement
Never disable a alarm by removing the battery because it goes off or "chirps." There is always a reason why it is going off even if you do not see or smell smoke.
Never paint any part of a smoke alarm.
Replace smoke alarm that are 10 years old or older
