Therefore we are providing you with a couple of fire prevention tips. You should test all smoke detectors at least once a month by pushing and holding the test button. When you change your clocks in the spring and fall you should also replace the batteries in all of your smoke detectors. Also it's a good idea to vacuum your detector, so that cobwebs and dust particles do not prevent the detector from working properly. If your smoke detectors are older than 10 years old, you need to replace them.
Detectors only work properly for about ten years.
Smoke detectors can be purchased from most hardware and general drug stores. If you live in Montgomery County, contact your local fire department, and we will replace your smoke detector for free. You should have at least one smoke detector on every floor of your house. Also you should have a detector in the immediately adjacent area next to any bedroom or other sleeping quarters. Usually, you should place your smoke detectors on the ceiling or on the wall within one foot of the ceiling.
