replacement is always an option for smoke detectors... most of them have a
limited lifetime because the radioactive source they use decays to a point that
they don't work any more.

Unfortunately, replacement is not an option. It is a two family house that I
built with my daughter and her husband. We have the "mother-in-law" side. There
are about two dozen of them wired throughout the two sides of a large house
with fairly new construction. I don't mind the chirping so much in my shack,
but the chirping over in their side is what is most of the problem. The system
is set up so that a fire on one side causes alarms to sound on both sides.
