No expert here, but I would think that with a 14 year old wireless
system, if you're replacing the detectors I
would think you'd almost have to replace the rest too.
Would seem a bit unusual that you could still buy wireless
detectors for that old of a system. Usually over that
time span technology has changed a lot and the stuff
is no longer compatible.
