Re: Wireless motions (DSC)

Do they use 2.2Ghz? �I have 2.2Ghz saturation in my house with both
802.11G networking and Sonos. �I also use X10 wireless appliance

what frequencies it uses. �And radio shack remote extenders (which use
RF). �And a microwave oven, etc.

Frankly, I hate wireless unreliability, and I use wired whenever
possible, but in this case I think I'm going to have to go wireless.

When first installer couldn't access my attic with his short ladder,
he suggested wireless, and quoted me a price (higher than wired). �I
think it requires a new zone, so two previous zones in my 8-zone
system will have to be merged to allow for a new zone.

Is your home a single floor house? Does it have a basement? Is the
basement finished? Does it have a drop ceiling?
Wires can be run from the basement to a first floor .... too.

Also, depending upon where your alarm control panel is, wires may be
able to be run in the attic with out having complete access to it. Do
you have recessed ceiling lights? Sometimes you can run a wire in the
attic by temporarily removing the recessed light cans if they are
strategically located.

Although you aren't planning an inside attic entrance right now,
there's no reason that a piece of *** rock couldn't be cut out of
the ceiling in a closest just temporarily. It's possible to squeeze
though ceiling rafters 16 inch on center and sometimes they are 24
inch on center. If you've got a good installer, he can usually find a
way to get a wire where it has to go.
