SYSTEM OPERATION
3
- To make a call, the visitor needs to press the button for the apartment, an audible tone indicates that the call is being
made and LED on the door panel illuminates. At this moment, the apartment's monitor(s) receives the call. If the
visitor presses the button for another apartment by mistake, the call can be cancelled by pressing the button for the
correct apartment.
- In systems with several access doors, the other door panel(s) will automatically disconnect; if another visitor wishes to
call, LED on the door panel will blink for 3 seconds. If the vocal synthesis module is installed on the door panel, the
message 'communicating' will indicate that the channel is busy.
- General panels (main): If the call is being made from the general panel, the interior panel of the building being called
and other possible general panels automatically disconnect; if another visitor attempts to call from either a busy
interior panel, an audible tone will indicate that the channel is busy and LED of the door panel will blink for 3
seconds, or from another general panel, an audible tone will indicate that the channel is busy and LED of the
general panel will blink for 3 seconds. The door panels of the other interior buildings will remain free to be used.
- General panels (main): If the call is made from an interior panel, the other interior panels will remain free to be used. It
is only possible to make calls to interior buildings from the general panels when their door panels are not in use; if an
attempt is made to make a call to a busy interior panel, an audible tone will indicate that the channel is busy and LED
of the general panel will blink for 3 seconds.
- The call lasts for 60 seconds, during which time an image appears on the apartment's master monitor after the call is
received without the visitor knowing, and the indicator LED and status LED of the master and slave monitor(s) will
illuminate (green). To view the image on a slave monitor, press button and the image disappears from the monitor
that was displaying it. If the call is not answered within 60 seconds, the indicator LED and status LED of the master
and slave monitor(s) will turn off. LED on the door panel will turn off and the channel will become free.
- To establish communication, press button of the monitor, status LED will blink (green), LED of the door panel
will then illuminate and LED of the door panel will turn off. Make sure that theCommunication with hearing aids :
hearing aid is 15-20 cm away from the monitor to ensure maximum audio quality during communication with the door
panel. Set the hearing aid switch to the T position, making conversation possible (inductive loop).Remember:
- To end communication, press button , and the monitor's indicator LED and status LED and door panel LED
will turn off and the channel will become free.

MONITOR SETTINGS
The configuration switch is located at the back of the monitor. It enables the monitorSW2
to be configured as master/slave.
SW2 configuration switch:
INT: Internal code of the monitor/telephone to set as master/slave.
Set the monitor/telephone as master, slave 1, slave 2 or slave 3 using
the SW2 switch with a code from 0 to 3 respectively. Taking into account the following points:
In the case of a single monitor/telephone in the apartment, the code to be set will always be 0.
In apartments, up to 4 monitors/telephones can be connected in parallel, all with the same user code but with
different internal monitor/telephone code.
The internal code identifies each of the monitors/telephones in the same apartment. This enables intercom calls to
be made to a specific monitor/telephone in the same apartment. In the case of intercom calls to different
apartments, and in the case of calls coming from door panels and from apartment front doors, all of the
monitors/telephones in the apartment always sound. The following considerations must also be borne in mind:
When master monitor/telephone 0 receives a call, it sounds immediately and slave monitors/telephones 1, 2 and 3
sound in succession, one after the other.
If a call is made from a video door entry panel, master monitor 0 shows the image of the door panel. During the call
time (60 seconds) and before establishing communication, the other slave monitors in the same apartment can
capture the image of the door panel if button is pressed, causing the image on the monitor that was displaying it
to disappear.

Button for receiving calls from the apartment front door:
CP
The Tekna HF Gtwin monitor features as standard the ability to receive calls from the apartment front door. This
feature precludes the need to use the bell by positioning a button between the 'CP' terminals of the monitor.
The ringtones vary depending on where the call is being made from, enabling the user to identify its origin. If a call is
made from the apartment front door during a conversation with the door panel, the monitor will emit a number of
tones to indicate so.
Note: The volume of the 'apartment front door call' ringtone will depend on the volume set for the ringtones on the
monitor (see p. 5).
