>Two indicator lights (red/green) serve as attention getters and ensure a far reaching call function when a respective message is displayed. The red light is used for system and emergency information, the green light for communication information. The lights are steady in normal situations and will flash in emergency situations.
>The ACPs give a long-range visual indication about the system status (e.g. PAX call active). They are installed at the ceiling in the middle of the aisle between the passenger/crew doors, close to
the attendant stations.
>The lighted segments are activated either continuously (steady) or flashing.
In case of "normal" calls they are not flashing (steady), in case of "abnormal" or "emergency" situations they will flash. Only the blue PAX call field will never flash, this will be always a "normal" indication
These indicator lights would be helpful in narrowing down if the emergency system was being engaged or not. Could potentially point to exploitation/hack of the PA system rather than rogue utilization of normal functions.
