Do Hard Wired Smoke Detectors Chirp?
There you are, lying awake at night when suddenly you hear a chirp from another part of the house. A few minutes later, the chirp sounds again. And again. Half-crazed you search out the chirping smoke detector with a low battery and rip it from its housing on the ceiling, determined to go back to bed. Sound familiar?
Truth is, that chirping is an alert that the battery in your smoke detector is running low. While smoke detection systems that are hard-wired to your home’s main power supply rely on the electricity in your home to work, they do have a battery backup. Once that battery begins to run low, your system will alert you with that annoying chirping noise until you replace the battery backup. The easiest way to avoid ripping the detector from your ceiling in the middle of the night? Set an alarm in your phone to change the backup batteries in all of your smoke detectors every six months. Not only will this keep your smoke alarms running smoothly, it will help you avoid the incessant chirping that causes so many people to disconnect their systems.
