[QUOTE=suesiegel;1462470]We have builder installed First Alert smoke detectors. They are four years old and I had just replaced the batteries two months ago with Duracell alkaline batteries. Yes, we do replace them every year.
In only two months one unit was sending out chirps in groups of three so I knew it was screaming for batteries
In any case,
if they are defective, the village Fire Dept will send a person out, no charge to replace them. The new ones at the stores do come with new batteries installed. . Be sure to have them before the FD comes out.
They do a good job and it keeps you off of a ladder for sure.
