Narrative:
At 31;000 ft in cruise a red and audio bleed air duct message occurred. Ran the appropriate QRH. At that time the engine bleeds closed and the aircraft started a slow decompression. We declared an emergency with center. At that point; started a very quick descent from 31;000 ft to 8;000 ft due to cabin pressurization rising. At 8;000 ft we finished the QRH; informed the flight attendants of the situation; and we diverted. We did not brace the cabin. Cabin altitude never went above 10;000 ft and the passenger oxygen mask never deployed. Landed with no further events.
