They would kill the battery in about 5-6 weeks and then they would chirp, usually about 3:30 in the morning. The digital display would show "Lb" which stood for low battery. I replaced batteries about 3 times and the same thing happened. I called kidde, they asked for the serial numbers of the units (I had 3) and they sent me 3 new units for free.
Thanks coal kirk,
I have one of them that does that exact thing, I will call and have it replaced.
Now that you mention it, it was the First Alert brand that was so bad about false alarms. Not the Kidde!
MY ERROR, Sorry!
