smoke alarms going nuts!!!
I had my smole alarms go off this morning at 4:30 AM, all of them approx. 4 simutaneously. No fire and no cause for concern. The alarms went off for about 30 secs stopped and came back on a couple minutes later and again a few minutes after that. Until I got a ladder and disconnected them all. Once off the wall they never went off again(while on battery backup).
This happened a few weeks ago but for only 20 secs then stopped pretty much forgot about it around the same time in the early morning.
The smoke alarms are wired and have 9volt battery backup. I have never heard these go off all at the same time before, didnt know that one tripped the others?? Like most alarms they chirp to let you know the battery needs to be replaced. Also, they are not the kind that detect carbon dioxide.
My first thought was dust buildup it the heating vents? For the most part the vents look fairly clean the return filters are changed often. Is this the heating system the most likely culprit for these to sound off? If so, where to check and what to check on the gas heat pumps? why arnt these alarms going off all the time or different parts of the day when the heat is on?
Unfortunatly, we had guests staying with us last night :o
thanks in advance...
