• When the visitor presses the call button the bell of the internal
unit is activated.
• There is a reassurance tone for the call having been made at the
external unit. If the call confirmation tone is not heard in systems
with several entrances, it means that another conversation is
taking place with another external unit installed on the same riser.
In the case where FT3346 - system engaged signalling module -
is installed, wait until the module turns off before making the call
again. In the case where FT3340 is installed, indication of the
system being engaged is shown on the display.
• At the internal unit, communication takes place by lifting the
handset.
• The button marked with the key symbol acts on the electric lock
of the external unit, activating it for about 2 sec .
• By pressing the call button on the external unit in video door entry
systems, the infrared LEDs (not visible to the human eye) for
illumination of the caller light up. The image remains on the
monitor for about 90 sec.
• See page 36 for microphone volume and call tone volume
adjustment of the telephones FT2428W/A.
• See page 35 for call tone volume adjustment and brightness of
the monitor Genius.
• See page 3 and 15 for adjustment of audio volumes on the external unit.
• To enable the
Self-ignition function, it is necessary to keep
push-button 2 pressed for more than 2 sec .
A confirmation tone is heard on completion of setting.
OPERATING NOTES
• Monitor Self-ignition (if the function has been enabled) takes
place by pressing push-button 2 . In the case where two external
units are installed, by pressing push-button 2 of monitor self-
ignition in succession, there is the possibility of displaying first
one image and then the other of the two external units on the
monitor (alternating function between two entrances).
• By replacing the handset of the internal unit, you have a few
seconds to replace the audio with the external unit.
From the moment of hanging up, a few seconds pass before
the image disappears from the monitor.
• The monitor set as Main (factory setting of bracket FT5714) lights
up on a call and on self-ignition even if it is inserted as additional
monitor with same user code.
• The monitor set as Secondary (see variant 18, 19) does not light
up on a call, but there is the possibility of self-ignite it by pressing
push-button 2 ( video request function).
In that case, there is no possibility of self-ignite the monitor.
Notice the difference between self-ignition, i.e. lighting up
of the monitor with the system free with the possibility
of alternating the image between two external units and the video
request only active after a call.
• Monitor and telephones with same user code all ring at the same
time (regardless of whether they are main or secondary) on a call
from the external unit and on a door bell.
