The Smoke Detector Is Old And Needs Replacement

Most smoke detectors are designed to last around 10 years. In most models, an expiration date should be printed on the back of the device. Replace your detector if it has reached its expiration date, but dont assume your system will work until then. Always conduct regular smoke detector tests to make sure your device is working, even if the printed expiration date hasnt happened yet.

If youve already changed the batteries and cleaned your detector but youre still getting false alarms, its a good sign to replace your detector. Batteries in old detectors also tend to drain out quicker, so you should probably get a new smoke detector if you find yourself replacing batteries several times a year.
