In case of smoke detected in any of aft toilet of a B777-200/300, where is the indication displayed? Is this at a single location, or at different locations?


From the 777 manual:

Each lavatory has a single smoke detector. If smoke is detected, an aural alert sounds in the lavatory and in the cabin. In addition, the lavatory call light flashes and the master call light at the associated attendant station illuminates. The EICAS advisory message SMOKE LAVATORY indicates smoke is detected in one of the lavatories.

The EICAS is a display in the cockpit.

It is treated as a fire, and the cabin and flight crews follow the set procedures to handle it.
