That isn't an Atlas panel, but an older C3 Bio panel. I'll check to see what supervision EOL resistors they specify on aux circuits, but these aren't typically used for readers, locks, and door position switches.
Now i didn't read the manual you linked but maybe the button is meant for a request to exit contact shunt than it is for a mag lock override. Every APAC region install I have dealt with they use buttons instead of motions and then use a break glass for mag release if needed. Would make sense since they don't include a 2nd switch of any kind.
Great writeup, but there you should make a correction about the Axis A1001 panel, it will support two doors, not just one.
This is wrong :
"An embedded access comparison would be Atlas to Axis A1001 with Entry Managercosting ~$550, but two Axis controllers are needed to manage two doors for a comparative cost of ~$1,100 and that pricing does not include a factory enclosure that will add another ~$50 - $75."
