Smoke detectors are one of the most important safety devices in your home. Every now and then, however, you will have a smoke detector chirp or set off for no reason. If this happens to you, follow the steps below:
If your smoke detector is battery-powered, remove the battery and insert a new one. If you still have problems, you should replace the whole smoke detector unit.
If you have hard-wired smoke detectors (120 Volt), flip your circuit breakers one at a time until your alarm turns off. You can then turn all of the breakers back on, except for the breaker that powers your smoke detector. You should now replace the broken smoke detector with a new one.
Always make sure to replace any faulty smoke detectors, whether they are battery powered or hard-wired.
