On a B787 aircraft, which panel indicates 'Smoke detected' when the lavatory smoke detector is activated?

Explanation:
The key idea is that lavatory smoke detection is a cabin systems alert. On the 787, the lavatory smoke detector feeds its status into the Cabin Services System, which is monitored by the Cabin Services System Panel. When smoke is detected, that panel lights up or displays a “Smoke detected” indication for the affected lavatory, so the crew can quickly locate and respond to the issue. The other panels serve different roles: the Forward Attendant Panel handles crew calls and announcements; the Cabin Systems/Area Control Panels show broader or zone-based system statuses but not lavatory smoke alerts; and the Master Call Panel is for intercom/call functions. So the CSSP is the panel specifically designed to show smoke in the lavatory.
