| Testing and Maintenance |
 Smoke alarms should be tested monthly. All of them have a test button that is pushed to check out the entire alarm, including its sensitivity (the amount of smoke it needs to set off). If the testing mechanism does not work in a proper way, replace the alarm immediately. Don’t use devices with open flame to test an alarm.
Elderly or disabled people may have difficulties with reaching their alarms to test them. There are smoke alarms on which the testing can be activated by shining a flashlight on it. Other types of alarms have an automatic test that activates at the same time once a week. These alarms can be used when proper testing might not otherwise be carried out.
The only maintenance that smoke alarms need is changing batteries (in those that work on batteries) and an occasional vacuuming of dust or cobwebs. A homeowner booklet is enclosed to every smoke alarm. This booklet describes how to use and take care of that alarm. Read it carefully and keep in a safe place to refer in future.
What if Your Alarm "ACTS UP"?
Generally smoke alarms are reliable devices, although sometimes they can be fooled by cooking fumes or steam. In case the alarm sounds when there is not fire, it needs to be moved to a place where cooking fumes or steam cannot reach it. Take it down and vacuum it out as it may contain some insects. If it still doesn’t work properly, just buy a new one. They are rather cheap and are sold at any local hardware store.
How Long Should Your Smoke Alarm Last?
Smoke alarms usually serve for approximately ten years. At that age they should be replaced, even if they seem to work. This will guarantee that the alarm will be working in case you need it.
Although today smoke alarms are cheaper than some years ago, they are more reliable. Therefore, it is not worth keeping an old one rather than buying a replacement.
