(a)
Cabin Programming - access code protected When you enter the 3 digit access code (level 1) and select the CAM layout selection mode, the respective menu comes on. The programmed layouts are marked with a < or > sign. The number of the active layout flashes. You can select a new layout when you push the related membrane switch. After selection, a new layout is marked and down loaded into the director. The system is updated automatically and CIDS works with this layout until a new one is selected and loaded.
(b)
PA level adjustment - access code protected (Ref. Fig. 059) When you enter the 6 digit access code (level 2) the PA LEVEL ADJ item appears additionally on the display. The following menus allow to adjust the basic loudness levels for 3 cabin segments and for the seperat attendant areas. These segments/areas are fixed and independent of the cabin zones. The defination is laid down in the CAM.

Additionally the 'automatic increase' levels for the cases 'engines running (flight)' and 'cabin depressurization (emergency)' can be adjusted. The acoustic loudness in the cabin for these auto increase cases is always according to the basic loudness level plus the auto increase level. After selection of a segment/area/auto increase case at the right side of the respective menu, the related currently active loudness value is flashing. It can be adjusted in +/- 2 dB steps by pushing the related +/- key at the left side of the menu. The respective loudness level in the cabin is updated immidiately (for the auto increase cases only if the cases are currently activ).
The following table shows the default values and the possible range:
range
| default I from I to
---------------------I-----------I----------I----------
segments/areas | 0 dB I -6 dB I +4 dB
---------------------I-----------I----------I----------
engines running | +6 dB I +4 dB I +8 dB
---------------------I-----------I----------I----------
cabin decompr. | +4 dB I +4 dB I +6 dB
If the max. or the min. limit of the range is reached, the
respective promt '<' in front of the '+' or '-' disappears. A
further pushing shows no reaction. For each page a 'RES' (reset)
function is selectable. If a segment/area/auto increase case has
been selected this flashing value becomes the default value after
pushing the 'RES'.
If non has been selected before pushing the 'RES' (no flashing),
all values of the page becomes default values.
E. Failure Detection and Transmission There are 3 types of test available in the CIDS for failure detection:
-
the power on test (activated after every power connection to the CIDS),
-
the continuous test (automatic periodical system test),
-
the manually activated test (via PTP, CFDS ...).
The status is transmitted to the CFDS (via ARINC 429) and ECAM (via discret outputs to the SDAC). The failure indication is possible on:
-
the FAP (CIDS caution light),
-
the PTP,
-
the CFDS/MCDU display,

-the ECAM displays.
In flight, it is possible to reset the illuminated caution light on the FAP. After landing, if the failure still exists, the light comes on again and the SYSTEM STATUS mode is displayed.
The failures are divided into 4 failure classes, 1, 1CAB (cabin), 2 and
3. The relation of failure classes and the transmission to the indicators
are shown on the Failure Transmission list.
