Does anyone have problems with these detectors. I have 2 houses that go off all the time. I have changed batteries and ck. connections. Builder bought from home depot.
Still pretty new or been in operation for some time?
I've mentioned a few times over the years, you need to take a vacuum cleaner to them once in a while to remove contaminants, including insects/spiders that can set them off.
Interconnected units that all go off when one is in alarm usually have a method of determining which one was the triggering unit.
