Neighbor's house has five smoke alarms wired so that all go beep when one
has alarm.
Two of them, at the end of the alarm line, suddenly started beeping. I
helped him replace the 9V battery in each but did not help. He bought
two new ones and I replaced. Did not fix.
Disconnected the red alarm lead on the one at the end of the line and it
stopped beeping but had no effect on other beeper.
Is it possible that the other three need replacing??? What is life of
these Firex smoke detectors?
The house is six years old in AZ.
Thank you for consideration,
Seamus J. Wilson


They are rated for 10 year life. Environmental conditions can shorten
that.

Smoking or dusty environment.

There is a recall out for some units:

If you were able to replace the unit without changing the harness you got
an older one because Kiddie bought them out and the new harness does not
match the old one.
