CIDS - DIRECTOR INTERFACES
VIDEO SYSTEM CONTROL UNIT
Audio and discrete lines are used for transmission of
the video sound to the dedicated zone, according to
the keyline control.
Low speed arinc 429 data buses are used for status and
bite system transmission.
PRERECORDED ANNOUNCEMENT MODULE
Audio and discrete lines are used for the broadcasting
of the BoardinG Music and prerecorded passenger address
announcements, manually or automatically activated by
controls.
The low speed arinc 429 data buses are used for
transmission of the BITE and status system and also
for remote control and selection of the prerecorded
announcements with the PRAM page of the PTP.
PASSENGER ENTERTAINMENT AND PASSENGER SERVICE SYSTEM
Audio and discrete lines are used for Passenger Address
announcement distribution according to the PA zone
keyline.
Low speed arinc 429 data buses are used for control,
monitoring and BITE system transmission.
The directors transmit a discrete signal to the
multiplexer Passenger Entertainment System unit in
order to initiate the test of the system.
DEU B
Two bidirectional middle data bus lines are used for
the transmission of the controls, audio data, BITE and
status system information of the attendant cabin
systems.
DEU A
Four bidirectional top data bus lines are used for the
transmission of the controls, audio data, BITE and
status information of the various Passenger cabin
systems.
TOP LINE CUT-OFF RELAY (106RH)
The top line cut-off relay discrete signal is used to
activate or deactivate the top line cut-off relays
when the emergency mode is activated, in order to cut
the supply of the type A DEUs and decrease the power
consumption.
PIN PROGRAMMING
Discrete signal is used to determine the active or
standby director.
PES ON/OFF RELAY (800MK)
A discrete signal is used to power the Passenger
Entertainment System : Multiplexer PES main and the
PES reproducer.
RELAY BOARD ANN LIGHT TEST AND INTERFACE
Discrete lines are used for activation or deactivation
of the indicator lights when a function or system is
activated or deactivated.
EXIT SIGNS RELAY (8WL)
Discrete line is used for activation or deactivation
of the EXIT signs when the NO SMOKING signal, from the
signs panel, or the "SIGNS ON" signals, from the
excessive altitude pressure switches, are activated
or deactivated.

FAP/AAP/PTP INTERFACES
FAP INTERFACES
The FAP is connected to the directors through two ARINC
429 low speed data buses.
Through these buses, the FAP transmits data for
controlling and monitoring of the cabin systems and
receives data from the active director for signalling.
The FAP also transmits, through these lines, its BITE
information :
- A discrete signal is transmitted to the EPSUs
for activation of the emergency lighting,
- discrete signals connect the FAP and type B
DEU for EVAC activation, reset and indication,
- an analog signal connects the FAP and the Water
QTY TMTR for potable water quantity indication,
- discrete signals connect the FAP with the
Potable Preselection Unit for the water
preselection from the FAP,
- an analog signal connects the FAP with the
Vacuum System Controller for waste quantity
indication,
- discrete signal, out of the FAP, for lavatory
lighting, pax reading lights and cabin
attendant work lights,
- a discrete signal for activation of the
lavatory water heater,
- a discrete signal for switching on the heating
on the FWD and AFT waste service panel,
- a discrete signal for the water/waste
pressurised water system in order to
