I know, I know,=20
I always run a four wire or at least a pair to just about every opening ( e=
specially on a prewire) but I thought that one audio glass break would cove=
r the area when wired it. It's all closed up now, but when I tested the sin=
gle GB it wouldn't pick up the tester from all windows so now I have to run=
 two detectors back to the panel on a single four wire but I want them on s=
eparate zones.
I'm not sure if you are asking me how to do it or offering to tell me how t=
o do it. I finally figured it out but I had to draw it out on paper. if you=
 want to know how, let me know.

Problem is, now that I've re-learned that, I wont know till next time I hav=
e another problem that I can't figure out what it is that I've "un-learned"=
, - - - - because I think I'm only working with about 8% of my bran smells =
now.=20
