Re: what is the best wire for a perimeter alarm

Well years ago I was able to see the difference between the old "relay"
systems and the new (at the time) transistor/IC systems. The transistor/IC
systems had problems the relay systems never had.

Lightning storms would cause all sorts of false alarms or would damage the
control.

Systems near radio station transmitters would have all sorts of problems.

Enormous warehouse buildings with miles of wiring had weird problems.

Installing shielded wiring or installing the wiring in metal conduit solved
these problems.
