Narrative:

I smelled an electrical burning smell. I quickly informed the purser. Then the fire bell went off. I immediately turned off the video system. The alarm stopped and the smell dissipated. The captain said he turned some fans off for an ill passenger in the last row of business class. If that was a cause of the electrical failure, I believe that is thought for concern. Callback conversation with reporter revealed the following information: reporter advised she didn't know what exactly caused the smoke. Several items had been turned off immediately including galleys, passenger entertainment system, recirculating fans, etc. All electrical items turned off were left off. Because the smoke dissipated immediately and completely, the captain decided not to divert and continued to destination.
