My smoke alarms were going off today and I finally isolated the problem to water dripping into it. The alarm is directly wired on the top floor of a 2-story house. I noticed what looked like condensation dripping from the conduit into the wiring box where the alarm is wired. I went up into the attic and noticed no water. Could this be condensation, if so, what can I do to prevent this from happening in the future?
Today is the first real cold day we've experienced since we bought the house in May (we are in the Chicago area).
