Thanks Bob,  I knew this was going to be tricky.  The signal delay thing
was not what I was thinking about.  Thanks for that thought.

I did find this: https://www.ebay.com/itm/304735959414

No matter I would have to get one of "something" just to 'test evaluate'
to make sure it can do what they want.

As for the staffing challenge....... Well that will be a challenge no
matter what.

Setting up a full system with relays and LED's, etc. will be a very
difficult install on this building.  Not impossible but difficult.

The one advantage here is that the whole building has WiFi installed.
I just don't know at this time how strong the signal is at each door.

Well, I don't even know which specific doors they want to cover.  There
is a meeting being setup next week to discuss.  I am trying to get my
thoughts and concerns together to be ready for that meeting.

Again thanks for the input.
