Hi,
One of the combo CO/smoke detectors here started acting up.
After consulting the 14 (!) different conditions that can
be signaled by appropriate combinations of lights and horns,
it seems this one boils down to:
"System error. You're SOL"
OK, fine. Buy a replacement (of course, this particular model
is no longer sold so that means researching *current* offerings).
But, it begs the question: what *is* the useful life of such
a device? IIRC, it was O(10) years -- so, this unit comes in
at roughly that point (9 years to the day?).
Also, am I correct in noting that the ionization type detectors
can't be "stock-piled"? I.e., buying extra for the future
just means any *unused* units will be dying at the same time
the *used* units crap out... (?)
However, that is *not* true of the photoelectric units?
Any similar consequences for the CO detection?
(of course, anything with a "built-in" battery is suspect...
"freshness seal"?)
