We have a set of Byron SD86 wireless doorbell chimes and the bellpush
is in need of replacement. The SD86 model appears to have been
airbrushed out of history - can't find any mention on Byron's web
site, and B&Q only sell SX and TX models - does anyone know of
anything compatible with the SD range, or have we got to buy a new set
- in which case I'll buy something else from somewhere else, as long
as it has a longer potential lifespan

Friedland have a range of wireless systems which you can get at the
merchants. Also with theirs you can install the electronic push inside
the house and connect bell wire to a standard external push. They also
have mains/battery option on the receivers. I have mine wired through
timers so the system can be turned off at night. I think they do 2
ranges of wireless and the cheapo version doesn't have those two
features.
