Are the alarms accessible in the sense that you can vaccum up dust, etc from
them ? I have read that dust and debris buildup can cause alarms to go
I would also give them a "test", using a match (with the hot flame), and
then ten minutes later, test them again with smoke, to see if they go off.
If you are not absolutely sure, just replace them.
the match theory only works on heat detectors. Today's modern smokes are
usually ion or a combination of ion and heat. Take them apart blow them out
with compressed caned air. Clean with a q-tip and to not touch any of the
parts inside with your fingers. The oils on your hands will have you doing
this again in a few months. I clean mine yearly as well as testing them.
If I am not mistaken, it is now suggested they be replaced every ten years.
Are you sure they do not have a battery back-up? If they don't, it may be as
simple as blowing they dust out of them, making sure not to cause any damage
I had this problem, posted to the group, and was advised to blow the things
out with compressed air. I did this (ordinary air-compressor air, no fancy
canned air), and it cured the problem. Spider webs are often a problem,
