Narrative:

On landing roll-out; at approximately 60 knots; we observed a cabin smoke level 3 alert with master warning light. At this point the captain stopped the aircraft on the runway and we notified the tower of our emergency. We communicated with the jumpseater and ran the evacuation checklist that resulted in blowing the 1L door and evacuating the aircraft via the deployed slide. No smoke or visual indications of fire were observed during this event and to this point the cause of the cabin smoke warning remains unsolved.
