Dec 6 - Smoke Alarm Problems

We have been having issues with our smoke alarm.  It has been going off and beeping for the past few days.  We changed all the batteries and that worked for a few days.  Then they started to go off again.  They don't go off at 8:00 in the morning, they go off at 2:00 AM.

So we determined that we needed to replace the old ones (they are 10+ years old and when we called they said they only last about 10 years).  It is also very cold, which could be causing them to go off.

Anyway, we hope to have the issue solved in the next few days!
