Sorry for the newbie question, but what happens if there is a splitter?

Also, is possible to tell - and if so, how - if there are one or more
splitters between the attic and the room?

And, another also, will the presense of one or more splitters affect
the other approach suggested by others on this thread (volt-ohm/multi
meter)?

At least thehick's other idea - using a portable tv - should still
work...

If there's another splitter, then it depends on the particular splitter
in question -- some will pass DC, others won't. If it doesn't pass DC,
then neither the buzzer nor the meter will register the battery's
voltage.

As for using a TV, it'll introduce some ambiguity there, too, since you
might have two (or more) equally good signals.

If you have the same number of wires in the attic as wall connections,
there's probably not another splitter.

If there were more splitters, it would be unlikely that they would be
hidden away somewhere. Splitters and connectors do occasionally fail and
they would have to be accessible for service. Depends on the
intelligence of the installer.
