If this has been answered before, sorry, couldn’t find a thread.
HO has a home that has several smoke detectors, linked with battery backups. There must be one bad detector, as they all alarm at random times. What is the process by which to tell which, if any, detector has gone bad, causing them all to alarm?

Some of the new ones have indicator lights on them that indicate which ones fired.
Try vacuum them, the dust will give false alarms.
If they are over 10 years old just replace all of them.
FireX has some with nice features and also have external hatch for replacing the battery without removing them.
At $12 per it is hard to spend a lot of time trying to trouble shoot.

A-holes. Hey every group has to have one. And I have been elected to be the one. I should make that my tagline.
On my smoke detectors, the 3rd wire is a red wire that interconnects them. You could pull all the detectors and disconnect that wire, then see which one went off.
First off, if they're older than 6-7 years just replace them all.
Otherwise disconnect colored wire.
Bill is correct. The indicator light on the alarm that triggered the alarm should blink after the alarm has been hushed and should not reset to steady until after you push the test button. Change the backup battery. This can trigger false alarms.
