I replaced all my smoke detectors about 3 months ago, and now one of them is driving me crazy by chirping constantly. They're all hardwired and interconnected. I've tried resetting it, and it stops chirping for a little while but then it starts again, sometimes after hours, other times just a few minutes. I even replaced the batteries, but that didn't help. Any advice on what could be causing this, aside from it being a faulty unit? My dogs are going nuts!

Sounds like a faulty unit to me! Since the others are working fine, that's a pretty good indication. You might want to check if there's a production date on it, too. Sometimes they have internal clocks that signal "end of life" chirps, and it could have been old stock. If it’s a warranty issue, your installer might need to handle it if they put in a defective one.
You should check if it's still under warranty. If yes, you can get a replacement. Calling the company directly could be your best bet! They usually have procedures for cases like this.
Try swapping that chirping detector with one of the others. If the chirping moves with the detector, then it's definitely faulty. If it stays at the same spot, there might be an issue with the wiring there.
