Re: what is the best wire for a perimeter alarm

["Bill" <bill190nospam@xxxxxxxxx>]

If you want the *best* wire... In addition to what others said, note that
all that wiring running in the walls/attic of a house acts as a big
"antenna".

The wiring can get voltage running in it induced by nearby radio
transmitters, etc. and lightning strikes - causing false alarms sometimes.

If you use "shielded" wire and ground one end of the shield (at the main
box), this will keep the outside electrical interference out of the wiring.

Shielded wire is like TV coax wire which has a metal wrap inside the jacket.
But you can get regular 2, 4, [or whatever] conductor shielded wire. It is
expensive though.
