The main front door is currently locked due to alignment issues that keep it from closing properly, so folks need to use a different door to enter and exit the building. If you’re using the automatic door opener on the accessible front door, please stick around long enough to see that it closes without anyone tailing you in who shouldn’t be here.
As far as I know, one can’t buzz anyone in through the accessible door (although I could be mistaken), so be aware that that could be a problem. Management is aware of the situation and is working to get the main door fixed.
I’m like 75% sure you can let people in through the accessible door by pushing 1 instead of 0 on your phone’s keypad. It’s not very well documented though.
We actually just tried out your theory, and alas, no luck. As far as we could tell, there’s no way to use the intercom to buzz someone in through the accessible front door.
