Necessary elements

Use one EL620/2PLUS module per panel.
In compositions with more than two pushbuttons, add one EL610D 10P module for every 10 pushbuttons until the desired number of pushbuttons (max. 120 telephones) is obtained.
In residential complexes with general panel(s) and several interior buildings, configure the interior buildings as described in the previous section, using a CD-2PLUS digital converter in each of them. The general panel(s) must be configured with 4-wire Plus technology.
The installation between the main panel and the interior buildings shall be 3-wire.
In panel assemblies with more than one horizontal module, use one long RAP-610D link cable for each additional horizontal module.
Choose 2Plus technology telephones: T-5720 o T-5822VD.
The maximum number of telephones in the same apartment is two (three in the case of the T-5822VD).
Use one FA-PLUS/C power supply for each panel, regardless of the number of telephones.
If there are CD-2PLUS, digital converters, add a FA-PLUS/C power supply for each of them.
Use a 12Vdc electric door release.
AC door release can be used by adding a TF-104 transformer.
