Title: CONSTANT false alarms - and always in the middle of the night!
Review: I bought 10 of these for my home, thinking I was "doing the right thing" and buying a complete, interconnected system.The first comment is that the instructions are incorrect on how to "program" them to announce which room has a problem. I figured it out on my own but the instructions are inaccurate.Second, and far more important, is that they randomly start beeping (not low battery beeps - but full, ear-piercing alarm beeps). Last nigth was the third time this has happened since recently buying and installing them. In this case, like others, a group of them went off for about 10 seconds. It's extremely disconcerting and I now have a very low level of confidence in this system. More than $600 later, I'm really disappointed.
