If you hear your smoke detector beeping, you should properly check your detector to ensure its functioning properly. The information below will help you to determine the reason your detector is beeping and how you can correct the issue.
If Your Detector is Hard-wired
The reasons why a smoke detector beeps depends on the smoke detector's design. Many newer homes utilize hard-wired smoke detectors. These smoke detectors operate off the home’s power. They also use a battery as a back-up in the event of a power outage. One of the most common causes of a hard-wired smoke detector beeping is that its battery backup is low or depleted. If this is the case, then replacing the battery should stop the beeping immediately. It should be noted that beeping will generally occur when the power to the home is cut off. Replacing the battery in this situation will not stop the beeping, but taking it out of the detector should solve the issue.
If Your Detector Is Battery Operated
If the smoke detector exclusively operates on battery power, then a beeping sound usually means that the battery power is low. Replacing the battery in this situation will stop the beeping.
If the Beeping Continues Despite Battery Replacement
In both types of smoke detectors, beeping can also occur if the detector malfunctions. Some smoke detectors have a built-in safety mechanism that causes automatic beeping when malfunctions occur. To verify that the detector is working properly, first replace the battery. If the beeping continues despite the replacement, then the entire smoke detector should be replaced. Here is how you know when to replace your smoke detector.
