However, if your smoke detector is battery-operated, you can simply replace the batteries yourself. If your smoke detector is hardwired into your home’s electrical system, then you will need to call an electrician to replace the battery. Smoke detectors typically have a lifespan of about ten years, so if yours is older than this, it may be time for an upgrade. If you have a smoke detector that is blinking red, this means that the battery needs to be replaced. If not, check the batteries again to make sure they’re installed correctly. If everything is working properly, you should hear the detector chirp or beep once. You can do this by waving your hand near the sensor or pressing the test button. Once the new batteries are in place, close up the detector and test it to make sure it’s working properly. Be sure to orient them correctly so that they make good contact when you close the compartment.

Once you know which size battery you need, purchase the appropriate number of fresh batteries from the store. Most detectors use AA or AAA batteries, but some may use a larger size like a D cell. This can be helpful if you’re not near the detector when it starts making noise.įirst, you’ll need to identify which type of battery your detector uses. However, some detectors will have a red light that blinks to indicate that the battery is low. This helps to alert you so that you can replace the batteries before they die completely. Most detectors will start making a noise when the battery gets down to a certain voltage. If you have a smoke detector that is beeping or chirping, it usually means that the battery is low and needs to be replaced. What does a blinking light on a smoke detector mean? 1.
