I have heard it said before that smoke detectors should be replaced every
ten years.  I would download the installation sheet for your smoke detector
and test them (if they have a magnet test) according to the sheet and
replace any that do not test within spec.  You may want to replace them
anyway as there was an ESL 400 series smoke recall sometime back then.
Currently I like the ESL 521 BXT for general 2-wire applications.
