Narrative:
Smoke alarm/returned to sju. We were 1/2 way between sju and ZZZ at FL380 when the aft lavatory alarm went off. I was called immediately with the flight attendant saying secondary indications of an odor. We turned towards sju and declared an emergency. The alarm was turned off manually by the flight attendant after 1 1/2 min with the odor dissipating. No more indications with alarm or odor. Landing and taxi into gate all uneventful.
