Notes
- If the maximum number of extensions is 5, you can use the PABX
FT105P.
- For the connection of name plate lamps read notes 6, 7 and 8 of the
installation instructions on page 111.
- If the control switching ON is necessary, connect terminal 4 of the timer
(dashed wire).
- To install a colour system, the ST7100CW video intercoms and the
MD41C, MA42C, MA43C, PL40PC, PL41PC or PL42PC camera
must be used.
- For wires dimensioning and video connection refer to the installation
instructions and table on pages 111÷113.
- For other types of push-button panels see the general catalogue.
Programming
When using the telephone interface FT11D with the telephone ST740 it
is necessary to programme the buttons dedicated to the intercom func-
tions (see page 204).
When using the PABX, the following programming must be absolutely
carried out: - intercom interface activation;
- activation to receive intercom calls. See page 210.
If the PABX is only used for the intercommunicating service, without
connection to the public telephone lines (URB1 and URB2), it is necessary
to deactivate the incoming and outgoing external lines with the following
programming: - how to assign incoming external lines; - how to assign
outgoing external lines. See page 209.
Connection of 1281E power supply-timer
instead of 1281 plus 1282E.
By adding 1281E to the schematics on page
221 instead of 1281 plus 1282E, the system
working will modify as follows:
- switching-OFF at the end of the timing only
- no control switch-ON interruption with the
videointercoms during external audio-video
connection. If the service is necessary, add
1471 relay in order to interrupt conductor 4.
