A selected call from the cockpit is cancelled, when all requested stations have
reset the function on the handset through pushing the RESET button.
The call function is automatically resetted after a time period of approx. 5
minutes, if no requested handset accepts the call.
All other interphone functions can be resetted through hooking on the handset to
the cradle or pushing the RESET key.
INDICATION/CHIME AND PRIORITIES OF INTERPHONE CALLS
There are optical and aural indications for the different types of interphone calls.
Additionally, these calls have fixed priorities.
INDICATIONS
During the dial procedure the dial information is displayed on the related AIP. At
the called station the respective light segment in the ACP comes on and a
related message is shown on the assigned AIP.
In the cockpit the EMER CALL indicator (for EMER CALL only) and the call
indicators on the AUDIO SELECTOR PANEL(s) are activated according the
initiated call.
CHIMES
In addition to the optical indications a chime is emitted through the loudspeakers
in the respective cabin area. These chimes consist of a sequence of one or
more tones with a high (Hi) or low (Lo) frequency.
The following table shows the different possibilities:
Type Frequency Musical Note
Lo II 392 Hz g’
Lo I 494 Hz b’
Hi I 587 Hz d"
Hi II 784 Hz g"
The aural annunciation of a cockpit call is done with the cockpit buzzer.
