One of the advantages offered by the BUS2 system is that no call wires are used. This is possible because the call is
made through the transmission of a digital code generated by the amplifier in the outdoor entry panel when a specific
call button is pressed.
This code is sent via the 2-wire bus to all terminals in the apartment (monitors/telephones). Only the terminal which was
previously programmed with said code will recognise it and generate a call tone.
Obviously, after setting up the system, it will be necessary to programme each one of the monitors or phones with its
corresponding call code. This is easy to do as displayed in the sections corresponding to each monitor and telephone.
In order to generate the specific code for each call on City button panels,
call extension modules
are used (one for
every 16 buttons). This module translates the activation of each button on to panel into a call code. (See connection
diagrams for the call extension module).
The City panels with 1 to 3 buttons do not require the installation of a call extension module (see panel pre-cabling
diagrams).
If a larger number of buttons need to be covered, two or more modules can be used, up to a maximum of 199
apartments allowed by to BUS2 system.

pressing the call button
Call code assignation carried out by the call extension module can be modified by using the
‘Mapping’
function
available in the BUS2 amplifier. See section ‘Advanced programming - mapping’).
