Narrative:

An A320 flight crew reported door 2R was not armed in flight and the cabin pressure light illuminated in climb. I asked if there was any loss of pressure or did the crew hear any squealing noise. No pressure loss and no noises from door. It appeared the door arm handle would not stay in the armed position. After conferring with maintenance I decided to bring the flight back to its departure airport. I also decided that an overweight landing was preferable to burning 15000 pounds of fuel and so advised the crew. The flight crew had also received a brake system 1 fault on ECAM. The affected bcsu was reset per the QRH but the ECAM message remained. I calculated the landing distance with the brake fault and we were legal to land. The flight crew declared an emergency and landed safely at 160000 pounds at a descent rate 100 FPM and airspeed of 155 knots using full flaps and medium autobrakes. Following landing the number two brake temperature reached 580 degrees.
