We just moved into a new home, and there's this pesky smoke alarm that's way too high to reach, and so far in the past two weeks, it's sounded off for 3-5 seconds at a time -- not beeping/chirping like the low-battery sound, but full on alarm mode -- and then shuts off on its own. It happens when absolutely nothing is going on, and almost always when DS is sleeping! No cooking, no smoke, no activity in the house. 5:30am one Tuesday, then 5:30am two Tuesdays later, and then the next day just now at 1:45pm. Anyone else have this problem?

I probably won't have a chance to climb up there and take a good look at it til the weekend, but I'm wondering if anyone here has any ideas or helpful experiences to share?
