Many models of smoke alarms chirp to indicate other erroneous conditions besides a weak battery. These situations include a battery failing to make a good connection, a dirty smoke alarm cover or that the smoke alarm needs to be reset.
In most cases chirping hard-wired smoke alarms can be stopped by pressing and holding the reset button. Wait a few minutes to see if the chirping stops. If it does not, try cleaning any dust out of the alarm with a compressed air can.
Smoke detectors use a chirping noise to alert users that the battery is low, so replacing the battery fixes most chirps. However, some units, especially those that connect to the home's wiring system, maintain the error code in the memory chip and require further steps to stop the chirping noise. On

Replacing a smoke detector's battery is crucial to a family's safety. After locating the smoke detectors and determining how often the battery needs to be changed, read the instructions, remove the back cover, remove the old battery, and replace it with a new battery before reinstalling the detector

It may be a noise of frustration or excitement, or it could be a way for cats to mimic the sound of the
