FEATURES
This system allows an intercom service up to 97 intercom door phones
maximum and with possibility of 4 simultaneous and independent
conversations.
It is possible to make a general call by means of a 5th independent
phonic channel.
The intercom door phones must all be programmed with two digits,
i.e. from 01 to 09, from 10 to 19, from 20 to 25, or any other number
between 01 and 97.
Connect the GENERAL CALL installation only if necessary. It is
recommended that the amplifi er be placed as close to the power
supply as possible and be connected to it with a shielded cable.
The power supply Ref. 926/3 is sized for an average installation of 25
intercoms. A larger number of intercoms will require additional power
supplies connected in parallel, each of which will supply power to its
own group of 25.
It is recommended that the power supply Ref. 926/3 be placed at the
center of the installation to minimize the cross-talk effect.
EQUIPMENT

WIRES
As indicated in Scheme SC101-0315E.
7 wires common to all the intercom door phones coming from the
power supply are necessary.
Each power supply feeds its group of 25 intercoms with 2 wires
common to the intercoms of that group.
In case the amplifi er is not used for the GENERAL CALL, do not
connect the wire L5 among the several intercoms. The common wires
are reduced to 6.
