Narrative:
On takeoff roll, we got a level 3 alert and right aft lavatory smoke indication on MFDU. Continued maximum power takeoff (used maximum power for windshear alert) rather than high speed abort and returned to field. On downwind, flight attendant reported no smoke or fumes of any kind. Reported to departure control that we had smoke indication in cabin and just wanted to return to dsm to check it out. We did not declare an emergency at that time, but ATC requested fuel and souls on board. We gave them 15.0 fuel and 101 souls. Completed normal checklists and briefed overweight landing and completed MFDU checklist. Landed 10 mins after takeoff at 94000 pounds gross weight. Agents in dsm informed me that ATC reported incident as an emergency. Debriefed with flight attendants. They agreed that incident went well under the circumstances. Had contract maintenance do overweight inspection and pulled smoke detector circuit breaker, placarded lavatory in accordance with MEL. Uneventful return to dfw. All is well that ends well.
