GENERAL DESCRIPTION & MAIN BASIS

The main feature that makes MDS Systems special is that they need no
call wires, so the installations are BUS type, with only one cable rising
through the building, interconnecting the Decoders installed on the floors,
in which the terminals corresponding to each floor are connected.

The call is generated in the decoder itself and sent to the telephone called.
In order to differentiate if the call comes from an outdoor panel or from a
guard unit, the call tone is different in each case.

Thanks to the BUS features, decoder and distributor installation split any
point of the installation into as many branches as required.

Both telephones and monitors can be basic models, but thanks to the
system features they work in privacy mode, that is, they are discon­nected while they are not called, avoiding other telephones hearing the
conversation in which they are not concerned or opening the door.

For the same reason, a telephone that has been left accidentally off the
hook would not affect the rest of the system.

It is also possible, from these standard terminals, to receive and gener­ate calls from/to the guard units.

This system is designed for medium to large installations in which the
traditional systems, with one call wire per telephone, would complicate
the installation.

For the same reason, this system is aimed at condominiums with one or
more general entrances (with or without guard unit) and several internal
blocks that can have, at the same time, one or more accesses with or

without guard units.

There is no practical limit to the number of blocks, entrances, guard units or dwellings that a MDS
system can manage.

The main features of the MDS systems are:

* Complete privacy of speech and door control, assuring privacy for your conversations.
* Standard terminals installed in the apartments.
* Bus type installation enables all possibilities of connection and extension.
* Floor distribution, making wiring fault and failure detection easy.
* Isolation, between terminals by means of the decoders.

We divided the MDS system into three types:

MDS DIGITAL

For installations in which any of these facilities are required:
 Searching resident's name through the outdoor panel display (electronic directory).
 Any type of access control and/or access restriction: proximity card readers, button key, numeric

keypad, etc. The system admits up to 32 accesses per Central, and manages access restriction
depending on different parameters: access number, day of the week and 3 timetable bands for each
user. See the MDS PC Programming Manual for further details.

 Additonal security (alarm system management, panic pushbutton to alert the guard or watching per-

sonnel, etc.). See the MDS PC Programming Manual for further details.

 Automation (lift control, lights on/off, watering sprinklers, etc.). See the MDS PC Programming Ma-

nual for further details.

The management capability of one MDS Central Unit is:

 Up to 32 panels. These panels can be:

- Access control panels

- Audio/video panels

- Guard Units
Guard units and Audio/video panels require a Switcher Module ref. 422

each one. The maximum number of Switcher Modules that one Central
Unit can allocate are:

Central Unit ref. 2420: 2 units.
Central Unit ref. 2421: 10 units.
This limits the maximum audio/video panels and guard units to allocate in

the same Central Unit.

 Up to 10.000 telephones or monitors
 Up to 1.000 sensor inputs
 Up to 1.000 relay outputs
 Up to 1.000 1L City audio panels (for single houses).

This capability can be increased with no practical limits, because it is possible
to interconnect up to 64 Central Units by means of the FXL (FERMAX LINK)
interface.

Each Central Unit can control up to 31 panels instead of 32, because one of them is used for the FXL (see
note).
The maximum number of Switcher Modules (and consequently the maximum mumber of audio/video
panels and/or guard units) are:

Every Central Unit ref. 2420: 1 units.
Every Central Unit ref. 2421: 9 units.

The number of telephones/monitors, sensors and relays for each central unit are listed above.

In these type of installations, usually in big condominiums with one or more general entrances and several
internal blocks, one Central Unit is used to control the general entrances. Each block is also controlled by
means of one Central Unit. All the Central Units are interconnected by means of the FXL.
As this is a multiplexed system, both FXL and BUS DECODER can be configured as bus, star or a
combination of both.

In the case of small condominiums (maximum 100 apartments per block) it is possible to use one Central
Unit only, with one, two or three Outdoor Panel for each block, sharing the decoders between the blocks.
Guard Unit and /or general entrances are also possible, but taking into acccount that the maximum number
of panels is 10. This is the called Multistair System, only available with MDS V 3.1 or higher.

DECODERS

These are the interface between the MDS BUS and the external devices (telephones, alarm sensors, etc.)

There are 7 different types of decoder to be used in the MDS systems.

 Audio decoder 4. Used in standard installations. Provides connection for up to 4 telephones.
 Audio decoder 8. The same as above, but providing connection for 8 telephones.
 Audio Isodecoder 4. In addition to the audio decoder 4, provides total isolation of each telephone

from the rest of the installation (including the other telephones in the systems) and other panic calls.

 Sensor decoder. Provides up to 8 alarm sensor inputs.
 Relay decoder. Provides up to 8 relay contact outputs.
 Panel decoder. Provides connection up to 4 standard 1 line City Panel.

All of them have the same appearance, with some parts that are common to all of them. These parts are
represented in the diagram below. Some specific parts of each one are represented in other diagrams.

MDS BUS connector

The MDS BUS is common for all types of decoders, independently of the decoder type. The connection
between the decoders and with the outdoor panel (or central unit) is by means of a bus consisting of 4
wires + 1 twisted pair (FERMAX cable REF.5918):

There is no limit to the number of decoders connected to an MDS system. The maximum number depends
on the devices connected. In any case, these specifications must be followed:

* Distance from the decoder to the telephone/monitor must always be less than 100 m.
* Maximum distance between the last decoder, and Outdoor Panel (or Central Unit), without repeaters

is 1.200 m.

* Maximum number of decoders without repeaters is 120.

Pag. 7

Technical Book

MDS

MDS

Since the decoders are digital devices they must be programmed before being used.
They can be programmed once installed or even in your warehouse (before installation), because the
assigned codes (telephone numbers) are stored into each decoder (EEPROM memory) and are not de­leted even in case of power failure. However, the settings can be updated as many times as required.

See the MDS Programming Manual for further details.

Programming process is different depending on the system where they are being installed: MDS-DIG-
ITAL, MDS-CITY or MDS-DIRECT. See the instruction manuals for details. In any case, the decoders can
be programmed from a PC using the Programmer Module Ref. 2427, which also includes the required
software (DECOWIN). This module is inserted into the Programming connector.

In any case, use a small screwdriver to press the PGM button, through the hole when the system requires
it, in order to codify the lines of this decoder. See diagram on the previous page.

It is also possible to program the decoders from the telephones, if audiodecoder is V1.1 or
higher, and always in MDS Digital installations, it not being necessary to press the PGM but­ton at the decoder, just the lock button on the telephone. See the MDS Programming Manual
for further details.

The LED indicator in the decoders gives us important information about their status:

OFF: decoder still has not been programmed.
ON: decoder is in programming mode.
BLINKING: decoder has been codified and is working.

* blinks twice every 3 seconds: indicates that the Central Unit in which the

decoder is connected to is in day mode.

* blinks once every 3 seconds: indicates that the Central Unit in which the

decoder is connected to is in night mode.

The DAY and NIGHT modes are a property of the central unit.

The audiodecoders have a telephone jack socket which gives the installer the possibility to plug-in a
standard FERMAX handset to speak from the decoder to an outdoor panel or to any telephone connected
to this decoder.

This telephone jack, which is connected directly to audio lines of the BUS installation, is a great help to the
installers when they are programming the system. An installer can stay at the outdoor panel for program­ming, while another goes by the decoders pressing the PGM button (or the lock telephone button if possi­ble).

Both can talk to each other through the handset connected to the telephone jack socket on the decoder
that they are programming at any time).

The technical data for each kind of decoder is:

Audiodecoder calling: 400 mA
Audiodecoder in stand-by: 40 mA
Sensor decoder: 40 mA
Relay decoder: 160 mA (maximum)
Operating voltage: 12 Vdc (minimum 10 Vcc)

Pag. 8

Technical Book

MDS

MDS

Another important point to take into account (regarding the decoders) is that the voltage along the bus-line
may drop, due to the wire resistance. To avoid this, it is necessary to install additional 12 Vdc power
supplies to regenerate the 12 Vcc in long installations.

You can use for this the REF.8840 Power Supply or the REF.8837 (12 Vdc 0,75 A), which can be enough, in
somes cases, to keep the voltage level in range. See table and explanation below.

On the other hand, in installations where the decoder bus wires are very long we recommend using a
bigger wire section.

The next table shows how many decoders can be installed in terms of the distance and section of wire
utilised.

It shows the number of decoders that can be connected in relation to the power supply point (before having
to instal an additional one), the wire section used and the type of power supply, ref.8837 or ref.8840 (in blue,

between brackets).

* In the left-hand column is the distance that a power supply can cover.

* In the top row the section of the wires to be used.

* In the intersection is the maximum number of decoders that may be connected with these specifica-

tions. (In blue, in brackets, if using a Ref. 8840 supply, whereas the others refer to Ref. 8837.)



We can "play" with these parameters in order to find
the most suitable relation between the wire section
and the number of power supplies required.

Example:

We have to stretch 20 decoders along 500 metres (1 decoder each 25 mts aproximatelly) in a very
long installation.

* We are using 10 decoders every 250m, so the best option is to use 3 mm

2

wires. Then we only need
one support power supply at 250m from the central unit. The first 250m are powered by the power
supply in the central unit.

* If using 1 mm

2

wires, we would need to add one power supply every 150m (we are using

approximately 7 decoders every 150m). We would need 3 additional Ref. 8837 power supplies.

Note:

* The wire section of the Ref. 5918 cable recommended by FERMAX for bus installation is 1 mm

2

.

* If we can plan the structure of the installation, it is best to use "star" topology as much as possible . This

would reduce the total distance between the central unit and the last decoder in each branch, and
consequently the number of additional power supplies.

* In any case, using thick wires in very long installations is the best, because this is the only way to avoid the

audio level decreasing.

Audiodecoder 4 Ref.2424 & Audiodecoder 8 Ref.2425

These standard decoders are used for audio/video installations.

The telephones connected to a decoder are isolated from the rest of the installation (except the ones in the
same decoder). Any fault in a telephone will not affect any other in the installation, except the ones installed
in the same decoder (possibly affected).

Once programmed, the decoder receives the call code from the decoder BUS and generates a call signal
to the corresponding telephone if the code is acknowledged, connecting audio bus to this telephone. After
the conversation, decoders detect when telephone is hang up and cut communication.

Each decoder output (telephone connector) works as a standard City Panel 1AP101, with the corre­sponding connections:

nº 1: power supply to microphone (electret type)
nº 2: audio from telephone to panel
nº 3: negative
nº 4: call signal

nº 6: audio from panel to telephone
The maximum amount of terminals to be connected to each output is 3 telephones (for the same apart­ment). The more telephones installed, the lower the call sound.

In addition to the audiodecoder features, isodecoders have individual isolation for each output. This means
that a failure in any telephone would not affect the rest of the installation, including telephones connected to
the same decoder. Moreover, isodecoders have extra features, such PANIC CALL terminal and activation
signal. Therefore, apart from the standard terminals that every decoder has, some extra terminals are
included for each output:

nº X: for special functions (to turn on a busy line LED in the telephones, generally)
nº P: panic call input (only in MDS-DIGITAL using panic call features)

Sensor decoder Ref.2429

This decoder has been designed to work with MDS-Digital systems only

It has 8 sensor inputs that can be configured either to use N.O. (normally open) or N.C. (normally closed)
detectors by means of a jumper located beside each input. In both cases the activation signal can be sent
to the central unit immediately or delayed, depending on the "time" parameter that commands the alarm
signal.

Instant alarm: signal activation is sent to the central unit the moment that sensor activation is detected.
Bear in mind that the detection stays on as long as the sensor keeps detecting. The time parameter for this
function is "0".

Delayed alarm: signal activation is sent to central unit when the sensor has been activated for a pro­grammed period of time (from 1 to 127 seconds or minutes)

"Time"and "sensor number" parameters are programmed into the decoder, and stay programmed even if
it is disconnected from the electric power. The "sensor number" can be programmed either from any
keypad with display or through a PC (by means of the Ref. 2466 module and the DecoWin software).
"Time" parameter is always programmed through a PC. See the "PC Programming Manual" for more
details.

Provides relay outputs for alarm and automation purposes. Exclusively to work with MDS-Digital systems.
It has 8 relay ouputs, which can be configured either as flip-flop (relay toggles in each activation) or as
timed mode (closing time for each relay can be set from 1 to 255 seconds). For "timed mode" a timer starts
to count the moment the relay is activated, releasing it once the time has expired.

Another interesting feature is the
FIRE ALARM facility.

This feature is achieved by means
of a connector (CN12), to connect
in series all the sensors we want

Special Decoders: Panel decoder Ref. 2436

Special decoder for hands-free communication system. It enables us to connect standard City panels to
the decoder instead of telephones. Moreover, by means of these decoders we can achieve a system with
standard panels in the tenant rooms (e.g. in hospital wards) allowing the patient to call a concierge or
porter. Then, they can attend the patient as required (priorities) allowing hands-free talking for the user. If
there is any electrical lock attached to the panel, the porter will be able to release it. In installations with
panel decoders and audiodecoders, the porter can communicate any City panel with any telephone. The
maximum number of City panels in an MDS-Digital installation is 1,000.

Panel decoders can be programmed from a PC, from any MDS-Digital keypad with display or from an
MDS-DIRECT Guard Unit.

Decoder PC Interface Module Ref.2466

This module is used for programming the decoders, either before installation, using the PC Programming
Connector included in each of them, or after installation (using any PC Programming Connector in any
decoder connected to the MDS BUS or even from the PC Programming Connector in the Central Unit).

It can also be used for testing procedures, after installation. See included DECOWIN instructions for
further details.

Do not forget to set the SW1-2 configuration microswitch in
the Central Unit ( PROGRAMMING DECODER mode) to ON
position, during the programming process, and return it to
OFF positon afterward. See page 14.

Video Distributor 4 Ref. 2418 & Video Distributor 8 Ref. 2419

These devices are used in video installations only. Video distributors are normally placed beside the stan­dard decoder and they are responsible for distributing the video signal for each monitor. Video distributors
are activated by the decoder they are attached to, whenever a call is generated in that decoder. The de­coder thus sends a trigger signal through terminal "V", which is used to activate the distributor. As with the
standard decoders, the video distributors are manufactured in two versions or models: REF.2418 for 4
monitor (normally attached to Audiodecoder 4 Ref.2424) & Ref.2419 for 8 monitors (when Audiodecoder 8
is used REF.2425).

The Video distributors do not need to be programmed.

(NIGHT mode).
Note that the information about the function mode of the guard units is stored in the central unit (not in the
guard unit), although it can only be changed by means of a guard unit connected to the central.

* Central units always leave the factory with guard unit deactivated (NIGHT mode in both normal and panic

functions).

* Installations in which the camera is activated from monitors (J2 in "E") require an extra common wire (CT).

The only difference between Ref.2420 and Ref.2421 is that the Ref.2421 includes an MDS-SWITCHER
MODULE, represented in the figure below, which is connected to the NR-2055 Module by means of a flat
cable, extending the capacity of 2 audio/panels (Ref.2420) up to a maximum of 10.

This MDS-SWITCHER MODULE allocates up to 8 Switcher Cards, which are inserted in the slots (see

5. Switcher extension socket.

VERY IMPORTANT NOTES:

* The two panels connected to the NR-2055 card do not need Switcher Cards, since the NR-2055 already

includes them, but use one switcher card for each outdoor panel you have to connect into the MDS­SWITCHER MODULE (Panel connectors 2 to 9) inserting it into the corresponding slot beside the connector.

* Configure the corresponding panel number matching with the panel number connector in which it has

been inserted. Se pages 22 to 25.

* Access control panels can be connected to any panel connector. They can be connected even directly to

any other panel already installed. Do not need switcher card, but it is neccessary to configure its dipswitches
with a panel number not used by any other panel in the same central unit.

* Use Panel 1 connector for the first outdoor panel and reserve Panel 0 connector for the second outdoor

panel (if there is one), Guard Unit or FXL (if the Central Unit is linked to others).

* In FXL installations, Panel 0 is always reserved for the FXL audio communication.

* J1 to ON position directly enables audio between Panel 1 and the decoder bus. Therefore, by inserting a

telephone handset in the test connector of any decoder it is possible to have check audio with the outdoor
panel. This feature is useful when checking or programming the system. The same happens for J0 (with
Panel 0). Whenever these jumpers are set to ON, the corresponding LED (P0 or P1) are on. The LEDs are
also activated when the Central Unit enables the outdoor panel. Do not forget to put J0 or J1 back to its
normal (OFF) position, after checking.
Equivalent LEDs are placed in the Switcher cards to indicate audio activated. The difference is that these
cards do not have activation jumper

* SW1-2 PC TEST MODE has to be put to ON position only when the Decoder PC Intercace Ref. 2466 is

being used, to program decoders or to check the system.
Note that system is then blocked and display shows the message "In Maintenance".

* In case the system is working as Digital Controller, SW1-3 is used to enable the PIN CODE feature. Permission

to open the door is then controlled by means of the PC programming. See PC Programming Manual for
further details.

Note

* The number of decoder that can be supplied by the same power source depends on the wire section used

and the distance between them, as long distances and thin wires increase the resistance.
See page 9 for the dependence between the distance and the maximum number of decoders that can be
supplied with the same power supply.
For the same reason, the number of monitors that can be supplied depends on the section and wire length.
60 monitors are estimated using the ref. 5919 FERMAX wire, and up to 300m. from the Power Supply up
to the last monitor.

* Using one emergency battery (Ref. 2070 or 2337)connected to each ref. 8840 Power Supply, the audio

system (not video) can work in the event of power failure. Autonomy is estimated at 40 minutes, but
depends on the use. Ref. 8837 Power Supply already includes an internal built-in battery.

Central Unit. This is to share the "pull up" and "pull down" resistances.

Jumper "J1" See note

Jumper "J2". See note

* If the system has more than two Central Units, cut both J1 and J2 in all the modules, except in one of them

installed in the middle of the system. This is to avoid excessive "pull up" and "pull down" resistances.

The microswitch "7" set to "OFF" (long call) indicates that it will first be necessary to dial the block number
in order to call the telephones (one or two digits) followed by the telephone number (four digits), when the
call is made from the general entrances. If the call is made from the corresponding block entrance only the
digits corresponding to the telephone number are required.

In the "ON" position (short call) it will not be necessary to enter the block number, but only the telephone
number, whether the call is made from the general entrance or from the block entrance.

Long call is necessary in places where the apartment numbers are repeated in two or more blocks, in order
to identify the block, when the call is made from the general entrance. Otherwise, short call is suitable.

The microswitch "8" set to "OFF" indicates that the panels installed in the central unit will be considered as
general entrances to a condominium (it enables calls to telephones controlled by other central units), while
in the "ON" position indicates that it is a central unit installed to manage a specific block.
Note: this treatment is different if we use the multistairs system provided by the MDS Version 3.1 or higher
(see page 25).

In Digital Controller Systems (SW1-3 in the central unit set to OFF) put microswitches 7 & 8 in the FXL card
to OFF to set the DC Extended Mode. It is then possible to link up to 64 central units which allows us to
manage up to 65.408 users). The total of accesses is limited to 31, as they are shared in all the central
units and access 0 is used (PANEL1) for the FXL network.

Examples:

* There is a condominium formed by 3 blocks, with apartments numbered from 101 to 150 in the first block,

from 201 to 250 in the second and from 301 to 350 in the third block.
We can use short call in this case, because there are no repeated apartment numbers. To call apartment
307 (in block 2) we will dial 3-0-7 either from the general entrance or from the block entrance.

* There is a condominium formed by 5 blocks. All of them have the apartments numbered from 1 to 150.

We have to use long call, because there are repeated apartment numbers in the blocks. To call apartment
25 in the 3º block, we will dial 3-0-0-2-5 if the call is made from the general entrance, and 2-5 only if the
call is made from the block entrance.

PC Interface Programming Card Ref. 2427

The MDS-Digital system parameters can be configured via PC, giving the possibility of programming the
system before installing it with all the advantages this provides: installations management (by files), user
lists... FERMAX has developed special software to manage and program the MDS-Digital systems: the
WINCOM. See the Basic and PC MDS Programming Manuals for further details.
By means of this card, it is also possible to change the language of the messages shown in the MDS­Digital panel display.

FXL Central Programming Module Ref. 2338

There is another choice for PC programming in MDS-Digital systems which is strongly recommended for
installations with several Central Units. In that particular case, it may be interesting to use a device that
allows the programmer to access every Central Unit from a common point, without it being necessary to
unplug the FXL card (as with the PC Interface Module above).

MDS Repeater Module Ref. 2339

Due to technical limitations, communications are not possible between Central Unit and decoder, panels or
FXL card more than 1200m away. For this reason, if longer distances are to be managed, the MDS Re­peater Module REF.2339 will be required.

MDS repeater can be used in the decoder bus (most common application), but also between Central Unit
and the outdoor panels or even between FLX cards.

MDS Repeater Module is also used for splits and/or branches in the installation. It is convenient to install a
power supply beside it, Ref.8840 or Ref.8837. If this module is used, see instruction manual for further
details.

notes:

* There is also a Secondary MDS Button Reader Ref. 23262 and a Secondary Proximity card Reader Ref.

23352, which do not have internal controller, but they can be connected to any Keypad Access Panel, via
CN2 connector. Then the system, if it has been properly programmed, will require a PIN code through the
keypad acces after the tag has been presented to the secondary panel. No configuration is required for the
secondary panel, since it uses the same controller as the Keypad to which it is connected. See PC MDS
Programming Manual for further details.

* As with the outdoor audio and video panels, the access panels have to be configured with a number not

repeated in any other panel in the same central unit.

* In contrast with the audio panels, access panels can be connected in any PANEL slot in the central unit.

They can also be connected to any outdoor panel or any other access panel in the system indeed. See
diagram above.

From factory, the guard unit is programmed as panel 0.
Further information about programming, features and use are included with the guard
unit.

Notes

* The guard units can work in one of several modes NIGHT, DAY or MIXED, TRANSFER-DAY, TRANSFER

MIXED and MASTER, depending on how the corresponding central unit has been configured. This can
only be changed by means of a central unit connected to it. Each of these modes and how to change them
is explained in the Operating Instructions that come with the Guard Unit.

* Guard units can be configured to manage "normal" calls from dwellings but also "panic" calls. In addition,

the system can be configured for one or more guard units to receive "alarm" messages. See the PC MDS
programming Manual.

* Entering programming mode you can know in which mode a central unit (and every central unit connected

to the FXL) is working. See the Basic MDS Programming Manual for further details.

Codification of the microswitches located on the back side of the display of the MDS Audio/Video and Wall
Guard Unit panels must be carried out.

These microswitches must be configured depending on the corresponding panel number and other fea­tures of the installation. See tables below.

In the case of the Desk Top Guard Unit, there are no programming microswitches, so the pro­gramming process is explained in the drawing on the previous page.

* Make sure that there are no repeated panel numbers between those connected to the same central unit.

* The audio panels must be connected in the central unit to the slot number corresponding to

the configured panel number. This is not neccessary in the case of the access control panel, which can

be connected to any other panel and any Panel nº connector as well.

* Remember that, in FXL configurations, Panel 0, in each central unit, is reserved for audio by FXL network.

Microswitches 6, 7 and 8 have function only in Audio/Video MDS Panels, but not in Guard Units. The

MDS DIRECT PANELS

The equipment defined in the MDS DIRECT system is the MDS Direct Audio Panel Ref. 2460 & MDS
Direct Video Panel Ref. 2461 for Audio or Video installations respectively (see figures below).

The MDS-DIRECTs main improvement, compared with the MDS-DIGITAL system, is that the outdoor
panels can work without any central unit.

The MDS-DIRECT can be combined with MDS-DIGITAL systems, giving the possibility of working as panel
in the internal blocks, providing the MDS DIGITAL panels for the general entrances.

Another possibility is combining MDS-DIRECT with MDS-CITY or even other MDS- DIRECT panels. In this
case one MDS DIRECT works as general entrance, while the MDS-CITY or other MDS DIRECT as internal
block entrances. See features figures and table on pages 4 and 5.

It is possible to program up to 100 access codes to allow the users to enter the building.

See the included technical information for further details.

VERY IMPORTANT NOTES

In condominiums with several blocks, remember when programming the DECODERS:
* That the 2 first digits of the numbers assigned to each decoder (house number) must coincide with the
Interior Block number previously assigned to the MDS CITY or MDS DIRECT Panel to which they are
connected.
For example: B B A A, with BB being the block number (one or two digits, from 00 to 99) and AA the
apartment number (two digits, from 00 to 99).

- Apartment number 1 of Block 1, will be programmed in the Decoder as: 101

- Apartment number 2 of Block 1, will be programmed in the Decoder as: 102

- Apartment number 1 of Block 23, will be programmed in the Decoder as:2301

- Apartment number 13 of Block 45, will be programmed in the Decoder as:4513

The block number must also be programmed in the corresponding Interior Block panel. See "Digitizer
Instructions" for MDS CITY Panels or "Instruction Manual" included with the MDS DIRECT panel.
* Then, a call must be made from the general entrance using the digits corresponding to the block number
+ the digits corresponding to the apartment number.

General Entrance-->block number + apartment number

* If the call is made from the Interior Block panel, only two digits (the ones corresponding to the apartment
number) are required.

E.g., To call the apartment number 19 in block number 7.
From the General Entrance Panel, key in 719
From the Block Panel, if MDS DIRECT, key in the number 19. The "7" is automatically inserted by the panel.
In MDS CITY, push the desired button (codified as 19 with the Call Extension Module, in this example).

MDS CITY PANELS

Basically these are standard City panels, but provided with a Digitizer Module Ref. 2440, which being
mounted in a window, allows the panel to be used with MDS systems, and one or more Extension Call
Modules Ref. 2441 or Ref. 2442 that convert each pushbutton action into a digital signal acknowledged by
the digitizer.

As the size of the panel depends on the number of apartments (pushbuttons), this system is convenient
only for combined MDS systems, to be installed in internal blocks with a few apartments only. In any other
case (internal blocks with more than 20 or 30 apartments) MDS Direct panels are recommended.

*The block number must also be programmed in the corresponding Interior Block panel. This can be done
from an MDS DIRECT panel, from an MDS Digital Central Unit or even from a PC, using the Decowin program.
See the corresponding technical information for each one.

*Then, a call must be made from the general entrance using the digits corresponding to the

E.g., To call the apartment number 19 in block number 7.
From the General Entrance Panel, key in 719.
From the block panel in MDS CITY, press the button to which the call wire nº 19 from the Call Extension
has been connected. If it is an MDS DIRECT panel, we simply key in the apartment number 19. The "7"
is added automatically by the Interior Block panel.

Every call wire from the Call Extension must be connected to the corresponding pushbutton
number (apartment number).
*For installations with several MDS-CITY panels to the same block, all the call extension
modules must be wired in the same order.
The number printed in each output in the Call Extension Module calls must match the
apartment number.

MDS City/Direct Guard Unit Ref. 2462

Generally, the MDS City/Direct Guard Unit offers 3 different operating modes: Day Mode, Mixed Mode and Night
Mode.

Both in Day and Mixed modes, it is possible to call all the telephones and/or panels from the guard unit. In Night
mode it functions as a MDS Direct panel.

As for reception of calls, the differences between different modes are:
In NIGHT mode the Guard Unit does not receive any calls but can

make them. In door entry phone installations it works as a General
Entrance panel.
In this mode, the display shows the usual instructions Dial Flat
Number and press %.

Informative

Display

In DAY mode every call from panels are captured by the guard
unit. From telephones and/or intercom panels it is possible to call
the guard.
A D character is shown on the top-left corner of the display.

In MIXED mode the calls from panels to telephones are not captured
by the guard unit, but the guard unit can be called from telephones
normally and from the panels just by pressing "%".

BLOCK DIAGRAMS and THUMBNAILS

This Technical Book presents the new FERMAX fashion for schematic diagrams: the THUMBNAIL system.
It makes the work of creating complex schematic diagrams based on the MDS Systems easier.
Every thumbnail is identified by a code (e.g.: MDS 95A). This code is the same as the one identifying the corresponding
detailed WIRING DIAGRAM shown in the ANNEX.
After making up your specific block schematic diagram with the necessary thumbnails, you can do the wiring one by
replacing each thumbnail with the corresponding wiring diagram from the ANNEX.

On the next page we offer some examples that should help you to understand how easy it is to manage the thumbnails
in order to elaborate any specific block diagram. Nevertheless, FERMAX is at your disposal to make any specific
diagrams you need. Please do not hesistate to contact us.

Example I: MDS DIGITAL

Video system, for one block with 2 accesses and 1 desktop guard unit. One branch.
