EMERGENCY LIGHTING SYSTEM PRESENTATIONGeneral

The emergency lighting system is designed to give sufficient illuminationto the cabin, to identify the emergency exit areas and to fulfil safe andquick escape from the A/C in emergency conditions. The system mustbe efficient in darkness and/or in case of smoked cabin, even if no A/Cpower supply is available.The Emergency Power Supply Units (EPSUs) are the heart of theemergency lighting system. They interface with the cockpit crew, thecabin crew, the Cabin Intercommunication Data System (CIDS), someA/C systems and the emergency lights.The lights are composed of:- the cabin ceiling emergency lights,- the staircase emergency lights,- the cockpit way lights,- the floor path marking system- the emergency slide lights,- the emergency door lights,- the exit signs.Note that to reduce operating costs and to improve reliability, allemergency lights use Light Emitting Diode (LED) technology.

EMERGENCY LIGHTING SYSTEM PRESENTATIONGeneral Architecture

The emergency lighting system can be controlled manually, either fromthe cockpit by the EMERgency EXIT LighTs and the cockpit way lightswitches, or from the cabin by the EMERgency lighting switch on theFAPs and a second cockpit way light switch.It can also be controlled automatically according to the A/C configurationby the CIDS network and by some A/C systems like the Doors and SlidesManagement System (DSMS) and the Electrical Power Generation System(EPGS).In all cases, the emergency lighting system is electrically powered by theEPGS through 18 EPSUs.If no AC power is available, each EPSU is able to supply the attachedemergency lighting components for at least ten minutes of operationthanks to its integrated battery.

LIGHTS SYSTEM MAINTENANCE (1)Lights System Safety Items

When you work on the lights system, make sure that you obey all theAMM safety precautions. This will prevent injury to persons and/ordamage to the A/C. Here is an overview of the main safety precautionsrelative to the lights system.High Intensity Discharge (HID) lamps contain mercury. If an arc tubebreaks, it is possible that the operator absorbs some mercury through theskin.In consequence, always wear safety gloves.HID lamps have very high temperature in working condition; 800C onthe outer bulb and 240C on the base.To prevent burns, let the bulb cool down for three minutes after theswitching off and disconnection before removal.HID lamps emit some UV rays.Thus, as a precaution, always wear safety UV glasses because of sunburnand conjunctivitis issues.The capacitor in the electrical circuit of the strobe light can keep a highvoltage charge for some minutes.In consequence, do not remove the strobe light for a minimum of tenminutes after you de-energize the electrical circuit.
