Wired ones are the code where I live, and the wireless ones do seem to have a built in battery that chirps after you remove the main battery. You’d need to do surgery to stop it.
Interesting. I’ve never heard about any of these. In Germany the alarm chirps when its battery is about to run out and stops when it’s dead. They are not wired.
I have never seen a fire alarm with a backup battery. Buy a different one maybe?
