• With the jumper in “N” position (default setting), the power supply is timed and present only while the timer is running. In
this operation mode, the video group will apply voltage to the riser every time a call is effected. The power supply will be
maintained for the whole timer lapse, then it shall return to a stand-by mode.
• With the jumper in “C” position, the power supply is constantly present in the riser regardless the timer activity. In such a
configuration, the power supply will be cut only briefly upon every visitor call, at the end of the each timer cycle and
whenever the lock release is activated ( if the auto switch-off is activated ).
This operation mode makes the power supply permanently available on the riser to serve the MV100 or MV3000 bell
circuit for the floor-call function. In practice, with this arrangement the addition of a “T” wire in the riser becomes
unnecessary and useless.
NOTE:
This function should be selected only in case of actual need, e.g. in systems with floor-call service when it is
impossible to add a “T” wire in the riser. In all the other cases, it is recommendable to set the module for the
default configuration.
MOUNTING
• The BM3000/X wall support has to be directly placed on the wall (in surface- mounting applications), or inside the
embedding box (in embedding applications), as shown in its instruction sheet. The system wires must enter the wallmount support through the proper pre-cut ports only. It is very important - particularly for large panels - to avoid possible
wires crossing. It is suggested to insert each wire through the port being closest to the module they have to connect.
ATTENTION
To run the connecting wires into the panel, use the pre-cut areas only. Do not drill further holes!.
ATTENTION
To let the connecting cable enter in the embedding box it is suggested to insert the system’s tube.
To avoid cables damaging due to rubbing on the box edge, it is recommended to cut the tube some millimetre
before the bottom of the metal box. This cut avoids tube interference with the wall support.
• Remove the modules front covers, then insert the modules in the wall support and fasten them onto the special hooks
With a slight turn, as shown in fig. 2.
• Remove the terminal block protective gasket ( “a” in fig. 7 ) simply by sliding it upward. Also, gain access to the terminal
screws by lifting the relevant rubber cap ( “b” in fig. 7 ) located on the module front ( pull the extraction tong, as shown
in fig. 8 ) Please note that the protective cap is anchored to the module by a screw to prevent its accidental loss.
• If correctly mounted, the module can rotate about its special support hooks, thus allowing an easy access of wires to the
relevant terminals( fig. 9 ).
• Once the connection is done, set all modules firmly in their final position - at the bottom of the wall-mount support - by
acting on their lateral winglet supports ( fig. 10 ). All wires have to be set well inside the specific raceways so that all
modules can be positioned correctly. To prevent pinching wires while closing the frame, pay attention to wires
distribution, especially at the corners and near frame support studs.
• Reinsert both side and the upper gaskets –removed previously – and verify their correct positioning.
NOTE:
Use special care in repositioning the gaskets, in order to preserve the panel IP33 protection rating.
• To complete the panel cabling procedure, add the ( black )
connection plates provided ( “d” in fig. 1 ), as shown in fig.3.
Such connection plates serve the multi-purpose of stiffening the whole mechanical assembly, supporting the front plates
and of interconnecting the modules electrically.. Thus, wiring the “common” wires of call-buttons and lamps is no longer
necessary, as they are replaced by an internal “connection BUS” which includes the aforementioned black plates..
Inserting the connection plates is simple matter, but it does requires a little bit of care, as the pins – however sturdy –
need to be handled gently. Should the connection be wrongly aligned, do not force on the pins, rather try to move it
gently right and left before making a new attempt. The first insertion could be a little bit more difficult due to the fact the
thin rubber cap protecting the socket from humidity has to be pierced.
Beside the (black) connection plates, one grey-white insert plate is supplied with each fixing frame. Differently from the
other one, this type of plate
( “e” in fig. 1) has one only row of pins. As it cannot serve the jumper function that ensures electrical continuity
between modules, it is then called “breaker plate” Mechanically speaking, breaker plates perform the same
stiffening/support function as the black connection plates, while breaking electric continuity of the internal BUS. Hence,
they are generally positioned at the bottom of the last module of the rightmost row.
NOTE:
In few special applications – e.g. installations with several entrances - it is needed to break the connection
between the audio module and the first button module. In those cases the “grey” plate must be positioned
between the said modules ( as shown in fig. 12 ).
• For larger panels configured in several rows, special “jumper cables” ( see fig. 1- f ) are provided together with the
frames. They are composed of a couple of connecting plates connected by a multi-core cable. Their purpose is to
ensure continuity to the internal BUS connection between the bottom module of a row and the top module of next one.
To avoid wires pinching, jumper cables are to be stowed orderly in the “raceways” provided ( as indicated in fig.13 ).
• Once these operations have been completed, the module assembly is complete and the panel is ready to work as soon
as power supply is provided. At this stage it is then possible to set some of the adjustable parameters (refer to the
Adjustments section for details).
• Next, proceed with the mounting of all module fronts: seat each one on its corresponding module, then push them into
position by gentle pressure (fig.14). Front plates are positioned correctly when they are firmly set onto their modules,
resisting the counter-pressure of the rubber gaskets of connection plates.
NOTE:
The connection plates also work as front plates supports. Therefore, they have to be mounted also above the
top module of the leftmost row, as well as below the last module of the rightmost row.
• Complete the panel with its frame – previously assembled after the instructions provided – to be secured to the wallmount support , as shownfig.15. In case of multiple rows, the central columns need to be mounted first, then the outer
frame. For a perfect installation, verify the modules and frame are well aligned, as shown in fig. 16.
• As shown in fig. 17, inserting the four corner pieces ( fig. 1-k ) and snapping them into their seats adds the last touch to
the beauty of your panel.
ADJUSTMENTS
The audio module provides adjustments for both the loudspeaker (EXT) and the microphone (INT) volume.During final
testing, potentiometers have been factory-set for the optimal result in mid-size systems.
During installation, it is possible to adjust levels as follows:
• Remove the panel fixing frame ( fig. 17 )
• Remove the front plate ( fig. 18 )
• Unplug the rubber gaskets covering the trimmers ( fig. 19 )
• Act on one, or both adjustment trimmers with a small screwdriver ( fig. 20 ), turning them clockwise (volume increase) or
counterclockwise (volume reduction), as needed.
• Place gaskets back in their seats. If this operation is not carried out correctly, the front plate cannot be mounted in the
right position.
• Place the front plate back onto the module
• Close the panel and secure the fixing frame.
MICROPHONE HOUSING (Fig. 1)
In case of Larsen effect, it is possible to remove the microphone from its original seat in the audio module
and relocate it into the video module seat as follows:
• Remove the microphone from its original seat with the help of a screwdriver.
Move the microphone to the new location on the video module and set the wires carefully into the dedicated
raceway.
