CONNECTION IN MULTI-CAR MODE
As mentioned earlier,
WITHOUT any need for extra cabling
, up to 4 MMk-656 emergency
telephones can share a single telephone line. It is also possible to mix them with MMk-643 and 644
models, provided that there are no more than 4.
Assignment of cabin number should be made using the
J9
switches as described in table 7.9.
The factory default setting is number 1. Any ordering may be used.
IMPORTANT
:
If no car is programmed as car 1, it will
NOT
be possible to receive incoming calls.
If two cars are programmed with the same number, it will
NOT
be possible to communicate
between them, and so neither will it be possible to reconfigure them remotely. Rather, they
will have to be programmed using the intercom.
Illustration 2: Connection in multicabin mode
An example of a sequence to switch car 1 to car 4, for a fixed line installation:
Whether by external call or the intercom. type:
*34#
The signalling using DTMF tones between the two telephones will be heard, and once the
voice message "Car 4" is heard, the car will have been correctly switched.
If the message is not heard, repeat the process.
NOTE: To perform the same sequence of car change in installations where the phone line is provided by
a GSM link, the following command should be used
*64#
.
