NewMech,
Westinghouse usually has a data plate on the controller. By your brief description it may say something like a 2BC-ERL. You may also find the model number at the top of a page from your print. If you can't find a data plate post a picture.

I would start by disconnecting the hall call if you can. Then work back from your door open relay circuit. If 44(?) is your door open, what is signaling for 44 to energize.

Once we know what you are working with things will go faster.

I still have some of my old info. If you PM your email address I will send you something to help familiarize you with Westinghouse.
