Can you provide a little more detail? If you have a CAV or CAM audio zone in this room and want local control using the keypad you'll need it.
If all you need is the "IR" portion and don't require the keypad interface you can install a stand-alone in-wall IR receiver liek the Russound 858 which can be tied into another keyad.
I've been a little out of hte loop on your project so if you can provide some more specifics about this, I'm sure someone can help.
Cheers,
Paul
