This enables the auto switch-on (audio and/or video communication without having been called)
of the door panel if it has this switch set to the ON position. In buildings with several door panels,
only activate on one of them; in systems with a general entrance door panel, it can be activated
on one door panel in each building.
Set to ON for monitor or telephone programming. After programming, return it to the OFF position.
The programming method is described on p.
for monitors and p.
for telephones.

On the general entrance door panel (EL501 mode), set to ON to programme the buttons of the
general entrance door panel or the monitors/telephones of the channel (building). The
programming method is described on p.
and p.

position.
Leave in the OFF position if it is a master door panel. Each system must have only one master
door panel; the others must be slaves (ON).
In systems with a general entrance door panel, a door panel from each channel (building) must be
configured as the master and the general entrance door panel must be configured as a slave. By
doing so, the user will know from which door panel the call is being made.
They define the code of the channel (building). In channels with more than one door panel, set the
same code for all panels; in systems with a general entrance door panel, set different codes for
each channel. Set a code between 1 and 120 for the inner channels (up to 127 if the general
entrance door panel is coded) and channel code 0 (factory setting) for the general entrance door
panels. The assignment of the code is carried out in binary form, as shown in the following
section.
Factory setting
Switches set to the OFF position have a zero value. The values of the switches set to ON are shown in the enclosed
chart. The code of the channel (building) will be equal to the sum of the values of the switches set to ON.
