    Nice addition to my Ring System. Now I'll be able to know if a Smoke/CO alarm has been triggered even when I'm away.

    Have used First Alert detectors for years. Recently had to get rid of one that had voice alert because it just was time to replace it, which was the max 7 years. Would have gotten another voice alert by First Alert if I had found two in my price range. So I just went back to one without voice alert, it works just as well.

    Work great when tested. They seem to integrate into Ring. Haven’t had a real fire yet to fully test and don’t one.
