A. Emergency Power Supply Units (EPSU) The EPSUs control and monitor the emergency lighting system. They are installed in the ceiling of the passenger compartment.
B. Power Supply Units (PSU) The power supply units provide the electrical power for the marking system of the emergency escape path.
C. Cabin Emergency Lights The ceiling emergency lights are installed to give sufficient illumination in an emergency condition. The lights are installed in the ceiling panels of the aisles, cross-aisles and exit areas. The exit marking signs are installed to show the position of the exits. The lights are installed near each passenger/crew door and emergency exit. The exit location signs are installed to show the position of the exit areas. The lights are installed in the aisles.
D. FPEEPMS The FPEEPMS is installed on the floor or on the seats (as applicable) at the aisle and the emergency-exit area. The system provides floor-level illumination of the passenger aisles and escape routes in the event that smoke obscures normal emergency lighting.
E. Integrated Escape Slide Lights The escape slide lights are integrated in the escape slides. They come on when the escape slides are deployed.

B. Cabin Emergency Lights The ceiling emergency lights are installed to give sufficient illumination in an emergency condition. The lights are installed in the ceiling panels of the aisles, cross-aisles and exit areas. The exit marking signs are installed to show the position of the exits. The lights are installed near each passenger/crew door and emergency exit. The exit location signs are installed to show the position of the exit areas. The lights are installed in the aisles.
C. Photoluminescent Marking System The system consists of a number of flexible photoluminescent strips. They are installed on the floor and on seats at both sides of the aisle and the emergency-exit area. The system provides floor-level illumination of the passenger aisles and escape routes in the event that smoke obscures normal emergency lighting. The photoluminescent marking system supplies sufficient light for eight hours in a dark area when it is fully charged. When the system is fully discharged, a charge time of at least ten minutes with full brightness of the cabin lighting is necessary.
