Need help doing an upgrade to the im-3303 system.

I've upgraded my system from a IM-2003 to a IM-3303 my only issue is how to wire the door speaker. On the old system there was a specially marked terminal on the PCB labeled door that one of the wires from the door speaker went to, the others went to the same terminals as all the rest of the room units. The new system has two terminals labeled door speaker but the speaker itself has 4, 2 for the speaker and two for a talk button. Where on the 3303 do I connect the talk button wires?
