MICROSWITCHES S1-1, S1-2, S1-3, S1-4 AND S1-5
The values of the microswitches S1-1, S1-2, S1-3, S1-4 and S1-
5 define the call address of the bracket in question with respect
to the external call unit.
To use the two-residence intercom call function, the users (door-
entry phones and/or video door-entry phones) must be set to
contiguous call addresses marked with the same letter
(AA...CC....YY) in the table on page 33.
Operation
• By pressing the call button, the visitor activates the white LEDs
for illuminating the person, the internal call ringtone (if the
Privacy function is not enabled) and displays the image on the
main monitor/s for approx. 60 seconds.
On answering the communication, the maximum duration of the
conversation is 90 seconds.
A call confirmation tone sounds at the external unit; in systems
with 2 or more entrances, if the external unit emits an engaged
tone instead of the ringtone this means that another
communication is already in progress with another external unit.
In case of a persistent short-circuit on the bus line, the external
unit emits an intermittent signalling tone.
• Communication occurs at the internal unit by lifting the handset.
• The brightness control and ringtone volume control are located
on the left-hand side of the monitor.
• The button marked with the key symbol acts on the electronic
door-release, activating it for about 2 sec.
• Self-ignition of the main monitor occurs by pressing Pushbutton
2 with the function enabled (see description on page 37).
In systems with 2 external units, it is possible to view the image
from one external unit or the other alternately ("toggle" function)
by pressing Pushbutton 2.
Monitor self-ignition is not possible during another conversation.
• For the intercom functions of the MAESTRO KIT System, refer to
page 34.
• For programming user addresses different from the factory
settings (1 and 2) refer to page 33.
• The total number of internal units with the same user code and
call repetition devices connected to the above internal units
cannot exceed 4. Connect only one call repetition device for
each internal unit. The MAX connection distance between the
internal unit and call repetition device is 20 m; use a screened
cable for the connection and do not run the cables near heavy
inductive loads or power cables (230V / 400V).
If inductive loads are connected, the connection of a 470nF
capacitor in parallel with the C.NO. contacts of Art. 1122/A is
recommended.
Main or secondary additional monitors
The setting of JP1 defines whether the bracket in question will be
managed as main or secondary. The external unit can manage up
to a maximum of 3 video door-entry phones or door-entry phones
for each Call button. When a call is made from the external unit, the
monitor switched on by the system will be that of the main video
door-entry phone.
Any other secondary monitors in the same residence unit will remain
off. By answering the external unit call from a secondary video door-
entry phone, the image is automatically displayed on the monitor.
The monitor of the main video door-entry phone will be switched off
and the image will be displayed on the monitor of the video door-
entry phone on which Pushbutton 2 - video request was pressed.
To display the image without activating audio communication with
the external unit, press Pushbutton 2.
In the classic MAESTRO KIT configuration, it is therefore possible
to have at most 2 secondary video door-entry phones and 1 main
video door-entry phone for each Call button, all powered by the
same Art. 1205/B (Variant MK/CC page 71).
It is possible to manage up to 3 main video door-entry phones
within the same residence unit (i.e. set to the same user code). In
this particular configuration, the additional main video door-entry
phones must each be powered by the special Art. 1212/B (Variant
MK/HC and MK/IC page 70, 71).
On receipt of a call from the external unit, the image will be
displayed on each of the main video door-entry phones connected
to the system.
In any case, even when using Art. 1212/B, a max. of 3 video door-
entry phones can be connected for the same residence unit. A
dedicated power supply is not necessary for any optional door-
entry phone.
S1-6, S1-7, S1-8
Setting the MAESTRO KIT operating mode
The table on page 34 shows the functions of the individual monitor
pushbuttons according to how the microswitches S1-6, S1-7, S1-8
are set.
Description of pushbutton functions
Door request exit button ➔ Pressing the Door request exit
button releases the lock connected to the external unit.
Actuator ➔ Pressing the pushbutton set in Actuator mode
enables activation of Art. 1256, which can be used to open
gates, up&over doors, etc., or to activate the cyclic camera
module Art. 1259C.
Free Pushbutton ➔ The indication Free Pushbutton means that the
pushbutton can be used as a C.NO. contact in the terminal block,
by means of suitable settings as illustrated in the MK/PC variant on
page 77.
Video request / Self-ignition ➔ Press Pushbutton 2 in this mode to
display the image on the monitor transmitted by the external unit,
even if no call has been made.
For use and activation of the service, see page 37. In systems
with two external units, it is possible to view the image from one
external unit or the other alternately ("toggle" function) by
pressing the pushbutton again.
