Narrative:

We had a problem with our pressurization system on the aircraft. System for pressure went into emergency pressurization. We had smoke building up in the cabin and the cabin was depressurizing. Ran checklist items. Declared emergency with center and started down out of FL370. Changed destination to tys and landed safely.
