3.10 Lighting-Introduction
Lighting Overview
This chapter provides a description of the passenger cabin lighting, and interior
and exterior emergency lighting.
Cabin Lighting
Cabin lighting is provided by white incandescent and fluorescent lights. General
cabin illumination includes ceiling, side wall wash, and night lights. These are
supplemented by reading, lavatory, work, threshold, and closet lights.
If a cabin decompression occurs, all fluorescent lights illuminate and the normal
lighting controls at the flight attendant stations are overridden.
Cabin lighting is controlled by the Cabin Services Module (CSM) located at
designated attendant stations at door 2L and the upper deck galley. See Chapter
2A, Cabin Management, for detailed information on CSM lighting operations.
If all main electrical power is lost, the night and supplementary night lights are
automatically turned on.
Closet Lights
A light is provided in each coat closet when normal cabin lighting provides
insufficient illumination.
Galley Lights
The lighting in each galley is controlled by a dimmer switch which provides for
high intensity work lighting and low intensity night lighting.
Lavatory Lights
Lavatories are illuminated by fluorescent lighting. With the airplane on the ground
and the ground service bus powered, the lights illuminate bright regardless of the
door position. In flight, the lights illuminate dim when the door is unlocked and
bright when the door is locked.

The reading lights are located in the passenger service unit (PSU) and provide
light from above the passenger seats. They can be operated from the individual
passenger control unit (PCU) or the CSM.
The reading lights are controlled by the Cabin Services Module (CSM) located at
designated attendant stations at door 2L and the upper deck galley. See Chapter
2A, Cabin Management, for detailed information on CSM lighting operations.
Work Lights And Threshold Lights
Each flight attendant station on the main deck is provided with a work light. Two
threshold lights are located at each main deck door. These lights are controlled by
switches on the flight attendant panels at each door.

Emergency Lighting
Interior emergency lighting consists of door, aisle, cross-aisle, escape path, and
exit lights, and luminescent exit signs.
The emergency lighting system is controlled by the emergency lights switch on
the flight deck. The switch can be used to manually activate the system or arm the
system for automatic operation. Automatic operation occurs if DC power fails or
is turned off when the system is armed. In this position, all interior and exterior
emergency lights illuminate automatically if there is a total loss of electrical
power. The emergency lighting system can also be controlled by the EMER
LIGHTS switch on the door 2L handset cradle.
When the emergency lights switch on the flight deck is armed, and the door mode
select lever is in the armed position, moving the door handle to the open position
causes the exterior fuselage light and the interior emergency lights at that door to
illuminate.

Escape Path Lighting
Escape path lighting consists of floor mounted locator lights located in the aisles,
cross-aisles, and on the stairway.
Aft pointing arrows are located in both the upper deck track and the main deck
Zone A track to assist in emergency evacuation. A lighted exit indicator is located
near the floor by each door and emergency exit.
When illuminated, escape path lighting provides visual guidance for emergency
evacuation if all sources of lighting more than four feet (1.2 meters) above the
aisle floor are obscured by smoke.
Battery powered exit lights are located at each cabin exit.
Flashlights
Flashlights are stowed throughout the airplane. These high intensity flashlights
illuminate automatically when they are removed from the stowage brackets. A
battery indicator light flashes every three to four seconds to indicate adequate
power. The light can be extinguished only by replacing the flashlight back into the
stowage bracket. The batteries cannot be recharged. See Chapter 8, Emergency
Equipment, for specific locations.

Cabin Interphone Calls
Cabin interphone calls are initiated by removing the handset from the handset
cradle (dial tone is heard) and dialing the two-digit code for the desired location
or type of call. The calling station hears a ring signal until the handset is picked
up. If the called station is already in use, the caller receives a normal busy signal.
If the caller has dialed a non-existent two-digit code, or is dropped from a call
already in progress, the caller receives a rapid busy signal.
When an attendant station receives a call, the passenger address system (PAS)
sounds a chime, and the pink station cabin interphone crew call light illuminates.
Interphone calls are prioritized in the following order: Pilot Alert, Priority Pilot
and Priority Cabin, All Call, Attendant All Call, and Station-to-Station calls.
Call Types
Pilot Alert
Pilot Alert is used to notify the flight crew about an emergency. The Pilot Alert
call is not inhibited at any time.
The dial code for PILOT ALERT, PP, on the handset:
• annunciates the call on the flight deck by sounding a single HI/LO chime.
Note: Pilot alert calls take priority over all other calls to the flight deck. A lower
priority call in progress is automatically disconnected. If more than one
pilot alert call is initiated, all applicable callers are connected via a party
line.
Priority Pilot
Priority Pilot is a private line between one designated cabin station (primary) and
the flight deck. This is accomplished by either station dialing the PRIORITY
PILOT code 33. The primary cabin station is normally at Door 1L.
Any other station trying to dial code 33 will receive a rapid busy signal
(connection not available).
Priority Cabin Call
Priority Cabin is a private line between two designated cabin stations (primary and
secondary). This is accomplished by either station dialing the PRIORITY CABIN
dial code 32. The secondary cabin station is normally at Door 4L. The primary
station, normally at Door 1L, can call the flight deck or secondary station. The
flight deck and secondary station cannot call each other. All three stations can be
on the priority line at the same time, when the calls are initiated from the primary
station.
Any other station trying to dial either code 32 will receive a rapid busy signal
(connection not available).

4.21 Communications-Passenger Address System
Passenger Address System
The passenger address (PA) system is used for making flight deck, attendant, and
prerecorded announcements to the passenger cabin. Entertainment audio and
boarding music can also be sent through the PA system. Flight attendants can
make PA announcements using the cabin interphone handsets. Those
announcements can be sent through the cabin interphone system or directly to all
cabin areas using the Direct Access switch located on the interphone handset
cradle. The handset cradles located at doors 1L, 2L, and 4L have Direct Access
switches.
Passenger address announcements are made by selecting the desired area on the
handset and pushing the Push-to-Talk (PTT) switch on the handset. Direct access
announcements are initiated by pushing the PA direct access switch on the handset
cradle.
Passenger Address Priorities
Passenger address announcements are prioritized in the following order:
• flight deck
• direct access
• priority announcements
• normal announcements
• pre-recorded announcements
• video system audio
• boarding music
A higher priority announcement overrides a lower priority announcement. When
the cabin interphone system is used to make PA announcements and a higher
priority announcement is initiated, the cabin interphone system resets and a dial
tone is heard in the handset.
There is a flight deck indication when the PA system is in use in the passenger
cabin.

Cabin Services Module.
The passenger service system switches provide electrical power for operation of
the overhead electrical units which contain the PA speakers, passenger reading
lights, and the passenger service unit (PSU) Row Call Light. The passenger
service system switches are located on the CSM.
The video entertainment system includes video monitors, video projectors, and
screens. An individual video system (IVS) is installed in the airplane which is
capable of providing audio and video from the tape cassettes. The audio can be
distributed through individual passenger headsets or through the passenger
address system overhead speakers.
Passenger address announcements from the flight deck or a flight attendant
handset automatically override the audio entertainment program. When the
announcement is complete, the program resumes.
Each passenger seat contains a passenger control unit (PCU). Passengers use the
PCU to select various in-flight entertainment system functions, turn the reading
lights on or off, or call for passenger service. A headset may be plugged in to listen
to the audio on the selected channel. The PCU includes switches for channel
selection and audio volume.
See the inflight entertainment vendor’s operating manuals for detailed
information.

Lavatory Water System
The potable water system is supplied from four tanks located beneath the cabin
floor. Water is supplied to the lavatory sinks and the toilet flush system. The tanks
have a combined usable capacity of approximately 420 gallons (1600 liters).
The tanks are normally pressurized with air from the airplane pneumatic system.
When pneumatic pressure is not available, alternate pressurization is
automatically provided by an electrically driven air compressor. Water is not
available while the tanks are being serviced.
Hot and cold water is available in the lavatories. The water heater is located below
the lavatory sink. An ON-OFF Switch is located on the side near the top of the
water heater. An amber light near the top of the heater is illuminated when the
heater is operating.
• low (approximately 105 degrees F / 41 degrees C)
• medium (approximately 115 degrees F / approximately 46 degrees C)
• high (approximately 125 degrees F / 52 degrees C).
All lavatories have push button, time delay faucets.

D6-30151-TBC (pax) 5.10.9
Lavatory Waste System
Waste water from the lavatory sinks is drained overboard through drain masts on
the fuselage. Toilet waste is flushed into four waste holding tanks located in the
bulk cargo area.
The toilet waste is flushed into four waste holding tanks located below the main
deck cabin, in the bulk cargo area. The two forward tanks have a capacity of 85
gallons (320 liters) each, for a total of 170 gallons (640 liters), and the two aft
tanks have a capacity of 65 gallons (246 liters) each, for a total of 130 gallons (492
liters).
The waste system uses a vacuum to collect the waste material and deposit it in the
tanks. At altitudes above approximately 16,000 feet, the pressure difference
between the cabin altitude and flight altitude moves the waste from the toilets to
the tanks.
Below 16,000 feet and on the ground, pushing the flush button on the toilet
activates a vacuum system and the flush cycle. The flush cycle uses water from
the potable water system, and lasts approximately six seconds. Once the flush
handle is pushed, there is an automatic 15-second delay for a system reset before
the next flush cycle can be initiated. This delay conserves water by preventing
consecutive flushes if the flush handle is repeatedly pushed.
Each tank system operates independently. The Waste Quantity Select switch on
the Lavatory Operation/Waste Quantity Module, at the Door 2R attendant panel,
can be used to check the waste quantity level of each tank. If a tank becomes full,
the toilet flush system for that tank shuts down automatically. The flush system
also shuts down automatically during ground servicing of the tanks. Lights on the
Lavatory Operation/Waste Quantity Module illuminate to indicate flush system
shutdown.
Note: Toilet blockages can occur if large objects are flushed down the toilet.
Items which commonly cause blockages are diapers, hand towels, cups,
and large quantities of toilet paper.

Lavatory Smoke Detector Operation
When smoke is detected in a lavatory, the amber Lavatory Call indicator
light/Reset switch, mounted on the exterior wall above the lavatory door, flashes
and a chime sounds in the cabin near the associated lavatory. The lavatory call
light at the associated lavatory flashes. The system can be reset by pushing the
Lavatory Call indicator light/Reset switch. When the Lavatory Call indicator/reset
switch is pushed:
• the lavatory master call light extinguishes
• the continuous chime is turned off
• the smoke detector horn silences
• the Lavatory Call indicator/reset switch extinguishes
• a smoke alarm suppression cycle is initiated in the smoke detector
Note: If there is still smoke in the lavatory, the red Alarm Indicator Light on
the smoke detector remains illuminated.
• a lavatory smoke alert message is displayed on the flight deck
When the smoke clears, the red Alarm Indicator Light extinguishes, the
suppression cycle ends, and the smoke detector is sensitive to smoke again.
Continue to monitor the lavatory until the red Alarm Indicator Light extinguishes.
Note: When the smoke detector has been activated by smoke, lingering smoke in
the detector sensor may cause reactivation. Blowing air into the detector
sensor (the small screen cutout on the side of the cube extending from the
unit) may clear lingering smoke.

Lavatory Fire Extinguishing System
An automatic fire extinguishing system is located beneath the sink in each
lavatory. A fire extinguisher discharges a halon vapor through either one or both
of the heat-activated nozzles. Both nozzles discharge toward the waste disposal
container. The color of the nozzle tips change to an aluminum color if the
extinguisher has discharged.
Lavatory Temperature Indicator
A temperature indicator is located inside the waste compartment below each sink,
behind and above the waste container. Grey dots on the indicator turn black when
exposed to high temperatures. If any dot has turned black or a nozzle tip has
changed color, the extinguisher has discharged.

Inoperative Toilet(s)
If one of the toilets does not flush, use the the Lavatory Operation/Waste Quantity
Module to check the status of the waste tank for that lavatory. If the waste tank is
full, placard all lavatories connected to the full waste tank as inoperative. If the
waste tank is not full, the affected lavatory should be placarded inoperative.
If one or more of the toilets do not flush, check the placard on the Lavatory
Operation/Waste Quantity Module at door 2R. Locate the LAVS INOP switch
applicable for the inoperative toilet(s). If the light in the LAVS INOP switch is
illuminated, the waste tank is full and the affected lavatories should be placarded
as inoperative.
If the LAVS INOP switch light is not illuminated, push and hold the LAVS INOP
switch (may require holding switch for up to 30 seconds) until the LAVS INOP
switch light illuminates. The vacuum flush system is now reset. If the toilet(s)
still do not flush, the affected lavatory should be placarded as inoperative.

the Waste Quantity on Lavatory Operation/Waste Quantity Module. Rotate the
Waste Quantity select switch through all four waste tank positions (FWD L, AFT
L, FWD R, AFT R).
The waste tank quantity level should be in the first half (from "E" to halfway) of
the green color bar for an unused waste tank. A waste quantity indication in the
yellow or red color band indicates an improperly serviced waste tank.
Maintenance should be contacted to service any tanks not showing the proper
indication.
