Thanks for the info Frank.  I've downloaded the handbook you
mentioned.  Yes, I'd definately be hiding the main unit somewhere.  My
neighbor had a Honeywell/Ademco installed by ADT.  Its control panel
is 2 feet from the front entry door! Yikes!

Initially I don't plan on having the system monitored by a Central
Office.  I will have it dial my cellphone.  If after all is working I
might get monitoring but to me, unless you have a GSM module, its too
easy for the telephone line to get cut.

Thanks again for the input.  I certainly appreciate it.
