First Alert called me back... Turns out there is a way to disable the Infrared Sensor for the Remote Control, IF it was manufactured after November 2009:
1) Remove the batteries from the cradle.
2) Put the batteries back in the cradle.
3) Hold down the "Test" button and slide the cradle back into the alarm
4) Release the "Test" button AFTER the first chirp.
The way to test if this works/doesn't work is to point a tv remote at it and press volume/channel up volume/channel down.
