Well the problem has been solved...........

......................to a point until I get it done!!!

At the Rear Door I will need to run outside conduit from a box that will
have 120vac receptacle with the needed power supply to provide 24vdc to
the Exterior Call Box.  This will feed the Aiphone GT-NSB Display Module
and GT-10K Keypad properly.

As for the Front Door I will need to tear out the "NEW" baseboard
molding to expose access to the basement as well as a portion of the
"NEW" wallboard to pull a new wire through from the Exterior Call Box
down to the basement panel to the needed power supply.  Then somebody
will have to make Beautifarkel repairs & painting to the big hole.

The typing above was rather simple!!  Doing it will NOT BE as simple!!

It is what the customer wants so, I will do my best to accommodate. ;-)

And they will monetarily compensate me!!!!
