My detector goes off when I cook. How can I stop this?
Either move your smoke alarm a bit further from your kitchen (giving room for small smoke-ups to dissipate), or install heat detectors instead of smoke detectors in the area. If you have an ionization detector, replace it with a photoelectric one, which is less sensitive to smaller smoke particles.
When should I replace my smoke detector?
Whether they're battery powered or wired into your electrical system, smoke detectors should be replaced every 10 years. Just moved in and not sure? Light and blow out a match just below the alarm to test it.
How frequently should I test my smoke alarm?
Once a month is a good maintenance plan. Either push the "test" button on your alarm, or try the match test above. You can also buy pressurized cans of simulated smoke that are designed to test your smoke detector, but be sure to follow the instructions exactly, or you risk ruining your alarm.
I have a battery powered smoke detector. How do I know when to change the batteries?
It should start to chirp. But you can also test it's functionality with any of the tests above. Even if it passes every test, you should replace batteries annually. A good reminder is to chance batteries when you're re-setting your clock for the fall time change.
How should I clean my smoke detector?
Vacuum it once a month to dust it and get rid of debris and cobwebs. Regular maintenance can also help get rid of residue from cooking vapors and insects.
How many smoke detectors should my home have?
You should have at least one smoke alarm on every floor in your house. An even better idea is to keep one in each bedroom. Heavy sleepers might not wake for an alarm sounding down the hallway. Be sure not to install them to near to vents or windows which can decrease their effectiveness.
