In case of short/circuit, if it is
*
removed before 2 minutes (approx.),
the door panel will automatically
reset; in case of more than 2 minutes,
it is necessary to switch it off and then
switch it on again.
DOOR PANEL INSTALLATION
Set the switch to OFF if it is the main door panel. Every system
must have only a main door panel; the rest must be slave door
panels (ON). Set as the main door panel the most remote from
the column.
Set the switch to ON for telephones programming.
Once the programming is finished, return the switch to OFF
position.
The programming method is described in page 63.
Set the switch to ON in case of call forwarding from the door
panel to the porter's exchange (when it is activated). Set the
switch to OFF if this function is not required (it needs a CD-
2PLUS converter and that door panel capture is activated in the
porter's exchange).
Set the switch to ON so that the tones emited by the door panel
are HIGH or set it OFF if the volume should be LOW.
The self-testing leds are placed together with the SW1
configuration dip switch.
