Smoke detectors are very easy to keep in good shape. Frequent testing and batteries replacement is generally all it takes but if you neglect these simple maintenance tips, your detector won't do its job when a fire starts.
Replace All Batteries and Lamps
On most models, batteries will last approximately 12twelve to eighteen months. If your detector begins to emit its low-power warning sound, replace the battery immediately with a fresh one and do the same for all your detectors this way it will be easier to maintain all your detectors on the same day. Always have a new battery on hand. Extra lamps for photoelectric detectors should also be kept handy so no delay occurs in restoring their function.
Bi-Monthly Tests
At least once every two months, test your detector by holding a lighter six inches under it. If you're testing an ionization detector, let the flame burn. To test a photoelectric unit, extinguish a candle and let visible smoke go into the detector. The unit's alarm should begin to sound within a few seconds, then, to stop the alarm, blow the smoke away from the detector. The detector, at this point, should stop the alarm, and you can rest assure it is working properly and that your family and home or business are safe.
Although most smoke detectors are equipped with a test button, using real smoke to test the detector is a more reliable method than pressing the test. In some older units, the button only starts the warning sound, and does not tell you whether the detector circuit itself is working. The newer detectors have more a refined test system built into them. These test systems simulate the presence of smoke in the chamber and imitates a real fire. Always check the package or instructions of your detector to see if it has this feature.
Keep in mind that smoke detectors are often your fist line of defense because early detection of smoke can help prevent devastating fires, loss of life, and damage to property. Smoke detectors are not expensive so if you have reason to believe that your detectors is not working properly, simply replace it with a new one.
