Yes, one of those digital entry locks would work if it wasn't for the
new panic hardware installed on the door.  Well maybe, I am not going
to get involved with trying to find something that will match up
properly.  I actually have a Aiphone Apartment access GT series that is
connected to a door strike.  The problem is that when I wired it there
was no pathway for pulling additional wires.  So the 24vdc digital
wire that does all the power and communication for the call stations
can't be used to power anything else.

My thinking is that if I had a battery operated keypad w/ relay I could
connect in parallel to the Aiphone relay to the strike.

Maybe I need to figure out a way to get a clean 12vdc wire to the
keypad.  It is finding a good 120vac source that can be used for a
easily/properly 12vdc wall wart installed.

I need to spend more time on site to think this out.

Later,
