On a B777-200, which panel indicates 'Smoke detected' when the lavatory smoke detector is activated?

• A. Cabin systems/area control panels (CSCP/CACP)
• B. Forward Attendant Panel (FAP)
• C. Master Call Panel
• D. CSSP

Answer: (A)

Smoke alarms from the lavatory are monitored by the cabin environmental systems, and the indication is shown on the Cabin Systems/Area Control Panels. These panels are the centralized place for cabin-area alerts and system status, so when a lavatory smoke detector is activated, the CSCP/CACP will display or light the message that smoke has been detected. The Forward Attendant Panel is for calls and cabin service controls, not for smoke annunciations; the Master Call Panel handles crew call signals, not environmental alerts. So the panel that indicates smoke detected is the Cabin systems/area control panels.
