 A. Cabin Illumination The cabin lamps are distributed in four strips throughout the cabin zones. The four strips in each cabin zone are divided for control purposes into two pairs. The two outboard strips are designated as WINDOW (WDO) lights and the two center strips as CEILING (CLG) lights. The system is designed

When on, the fluorescent lamps can be selected to 100 % (BRT), 50 % (DIM 1), or 10 % (DIM 2) intensity. Each fluorescent lamp is installed in a holder which contains an integral ballast unit. The units are supplied with 115VAC from busbars 212XP and 214XP through circuit breakers 300LG thru 307LG (cabin lighting) and 308LG (entrance lighting). The lighting system is controlled from the Flight Attendant Panel (FAP) 120RH and from the AFT Attendant Panel (AAP) 126RH.

 MAIN ON - when pushed, switches on the cabin zones and entrance areas lighting with 100 % intensity. It also causes the integral light in all BRT, WDO and CLG membrane switches to come on.

 (2)
 MAIN OFF - when pushed, switches off the cabin zones and entrance areas lighting. It also causes any general illumination membrane switch which is on to go off. This function is disabled in flight.
