Within the last year or so there were postings here about smoke alarms

Spiders, dust and old age can cause it.

Oh my goodness, mine just did that to me a couple of weeks
ago at about 4am. My old programmer's habit kicked in and I
was halfway down the hall in 3 steps before I realized it wasn't
my beeper.

Since my detector is new and the batteries were changed, I'm
going with spider. Makes sense to me.
