Hi, I joined just to see if any of you might have more information on this smoke alarm that has been harmlessly hanging in the hall of my house until this week. Yesterday in the middle of the night it went off for about a second and then very early this morning it went off for about 30 seconds, scaring me and my dogs half to death.
It has an insanely loud buzzer type sound & a red light that has always been on, but since it never did anything we just left it alone.
while trying to figure out if it was actually a smoke alarm, I found this thread. Thanks for any information you can give me.
