1 – MP120 SYSTEM
1.1 GENERAL DESCRIPTION
1.1.1 SYSTEM ARCHITECTURE
The MP120 system is an antitheft and safety alarm wire system suitable for individual users both in the residential,
industrial or service industry fields. The inputs can be configured as unbalanced (N.C.), single-balancing and dual-
balancing inputs.
The control unit, inserters, keypads and input/output expansions are connected with one another through a bus. The
detectors, sirens and other signalling devices are, on the contrary, connected to the inputs and outputs available in the
control unit and the other aforesaid devices. Using the bus makes cabling much easier and allows you to save money,
since not all the connections need be terminated directly to the control unit. For instance, if you wish to ensure the
antitheft feature as well as local actuation for an annexe (e.g. garage, warehouse, shot), you will just need to run the bus
cable to the annexed building, and the bus cable shall be connected to an inserter (or keypad) and an expansion to
which the alarm detectors will be linked.
The MP120 system may, if equipped with a communicator, send telephone, voice alarm messages with numeric
protocol (to remote surveillance agencies); moreover, it may also be controlled remotely through the telephone (incl.
mobile phones) and make use of remote assistance. The system is programmed through any of its keypads, and also be
connecting the control unit to a PC equipped with the Fast Link software, after the control unit has been equipped with
the interface with the RS232 port.
1.1.2 BUS
This is the connecting line that transmits, through four wires only, both the information and the 12 V- power supply
between the control unit, keypads, inserters and expansions (as far as expansions are concerned, the 12 V- power
supply, required to power the detectors connected to the expansions themselves, shall be provided separately).
This arrangement makes cabling much easier, since it allows you to use different types while reducing the number
of cables required for connections. Below are the types that can be used.
PERIPHERAL UNIT CONNECTION
The 4-lead bus cable (2 leads for the data, 2 leads for the 12 V- power supply) is enough only for the keypads and
inserters. As regards expansions, if they are not powered locally, two more leads for AUX 12 V- power supply shall
be run from the control unit +/- S terminals (in this case, take care that total absorption will not exceed the current
that can be delivered by the control unit power pack).

Below is the connection diagram for the four bus wires to the devices:
1.1.3 INPUT AND OUTPUT ARRANGEMENT
The individual system detectors are physically connected to inputs. One or several detectors may be properly
connected to each input (if several detectors - to be connected in series - are available, you will not be able to
identify the device that triggered the alarm). Yet, one single detector cannot be connected to several inputs.
The inputs may also be associated to predefined sectors, numbered 1 through 8. Each input may be associated to
one or several sectors: one input associated to several sectors will signal an alarm even though only one of the
associated sectors is ON. The sector is used to group all the inputs that perform the same task, in order to allow
such inputs to be controlled (the sectors - not the inputs - are switched ON and OFF). Let us consider a company,
by way of example: all the raw material warehouse inputs may be associated to a sector; the finished product
warehouse inputs may be associated to another sector; the manufacturing department inputs may be associated to
one further sector; and the office inputs may be associated to one additional fourth sector. By extending a similar
example to a residential building, the apartments may be associated to a sector, and the garage may be associated
to another sector.
Finally, another possible macro-group is available: the area, which makes it possible to group one or several
sectors and further facilitate system control. Three predefined areas (A, B and C) are available, which cannot be
renamed. In the company example above, the two warehouses and the manufacturing department may be grouped
within one single area, in order to be able to actuate the antitheft feature by means of one single command at the
end of the working day.
To sum it up:
•the inputs shall be associated to the sectors; they cannot be associated directly to the areas;
•one input may be freely associated to one or several sectors;
•8 predefined sectors are available (numbered 1 through 8);
•a number of inputs ranging from 0 to the total of the inputs available in the system may be associated to every
single sector;
•the sectors may be associated to the areas (each sector may belong to several areas);
•3 predefined areas are available (A, B and C).
The actuating devices (sirens, blinkers, solenoid valves, presence lights etc.) are connected to the outputs. The
outputs may be associated to the inputs, sectors and areas.

1.2 SYSTEM COMPONENTS
1.2.1 MP120 CONTROL UNIT
The MP120 multifunction control unit can manage separately the signals for six different
types of events: attempt at break-in, attempt at sabotage, fire start, technological alarms
(e.g. flooding), emergency and panic calls. Detectors can be divided up to a maximum of
8 sectors, which may be freely grouped within 3 areas.
The control unit is configured through programming by means of a system keypad or, for
your greater ease, a local PC connected to the control unit (the latter must be fitted with
the TTL/RS232 interface and the Fast Link software, which also allows for remote
programming).
To program by means of the keypad, an easy-to-use menu is available in eleven
languages (Italian, French, English, Spanish, Portuguese, German Swedish, Finnish,
Czech, Polish and Romanian).
The control unit features the following:
•8 inputs with uncoded naming;
•1 24-h input permanently ON (anti-tampering feature);
•1 input for mechanic actuation/deactivation key;
•1 relay output;
•4 OC PNP/NPN electric outputs.
The power for all internal circuits and devices is supplied by a 230 V~ - 12 V−power pack and a 12V−booster
battery. Both the current delivered by the power supply and the battery capacity vary depending on the control unit
version. Other control unit features include:
•protection against opening and removal;
•9 access codes able to be controlled;
•storing into the memory the latest 250 events occurred, e.g. break-in alarm, sabotage, system (or sector)
actuation and deactivation, with an indication of the event's date and time;
•direct connections can be made between the inputs and outputs (actuating an input will actuate the
corresponding output, too);
•weekly time programmer control.
The MP120 control unit capacity may be increased through:
•the EP100, ES100 and ER20WL expansions with auxiliary inputs and outputs;
•the remote communication options offered by the PSTN telephone interface (included in some versions);

Warning! The type chosen will apply to all the control unit inputs, including 24-h.
All the control unit alarm inputs are referred to the positive.
Differences between the various types of inputs
The choice of the input type affects the way in which the detectors are connected and the alarm is distinguished.
N.C. inputs are the simplest ones and may signal opening only. Dual-balancing inputs are the most complete ones:
in fact, input opening can be distinguished from tampering. Single-balancing inputs are half-way, as illustrated on
page 21.

"KEY" INPUT (MECHANIC KEY) - TERMINAL 37
"KEY" input
The KEY input is used to connect a mechanic key and can, as far as actuation and deactivation are concerned, be considered
as a "main switch" for the system. Its behaviour depends on how it is configured through programming (system options):
•impulsive: it switches all the sectors ON and OFF, yet allowing the same to be able to be done with the keypads and
inserters, too;
•hold-on: it switches all the sectors ON and OFF. It takes priority over the other control elements (keypads and inserters),
which cannot actuate or deactivate the sectors any longer.
"KEY" input connection
If the KEY input is used, connect an external switch (for hold-on control) or a button (for impulsive control) to the negative (-
S). Either the switch of the button shall be key-controlled due to safety reasons, in accordance with the “IMQ CERTIFICATION
- SAFETY SYSTEMS” indications on the last page.

2.3.4 OUTPUT HARDWARE CONFIGURATION
Control unit outputs U2, U3, U4 and U5 are of the configurable Open Collector type, choosing from between PNP
(preset) or NPN. Each output must be configured individually, by moving the respective jumper placed on the
control unit master card (see the figure of paragraph 2.2 FITTING OPTIONAL ITEMS AND ACCESSORIES for
their positions).
The max. current that can be delivered is 100 mA (for output U2) and 10 mA (for each of outputs U3, U4 and U5).
Open Collector outputs
To put it in simple words, the Open Collector electric outputs can be considered as electronic circuit breakers”.
In case of PNP output, at rest, the electric output is +12 V, which will be missing in case of alarm.
In case of NPN output, at rest, the electric output is 0 V, which will turn into +12 V in case of alarm.
The Open Collector outputs can be used to control relays or signalling LEDs. The Elkron MR02 module features 2
free-exchange relays (1 A - 24 V) which can be controlled by the OC electric outputs.

Warning! Always close unused inputs: to the positive, if they are of the N.C. type, with a balancing resistor
(22 kΩ) if they are of the balancing type.
The specific input task (break-in, robbery, panic, technological, fire) will be subsequently specified through
programming.
Output connection
The control unit outputs can be reached by connecting alarm devices (sirens and blinkers), signalling devices
(LEDs or buzzers) as well as other devices made to operate automatically when a detector is actuated.
To connect the outputs, proceed as follows:
1. Connect the alarm devices (e.g. siren) to output U1 (potential-free relay, max. 1A - 24V) (such output cannot be
programmed freely):
Event Actuated system Deactivated system
Break-in ■
Tampering ■If programmed
Panic ■■
Fire If programmed If programmed
The relay rest status may be programmed as normally open (N.O.) or normally closed (N.C.).
2. Connect, if you wish so, other devices to programmable outputs U2, U3, U4 and U5, considering that:
•output U2 (max. 100 mA) is preset as a tampering output;
•outputs U3, U4 and U5 ensure a maximum current of 10 mA.
The output specialization (break-in, tampering, robbery, panic, technological, etc.) will be subsequently indicated
through programming.
Bus connection
Connect the bus 4-lead cable (which will make the control unit, inserters, keypads and any I/O expansions to
communicate) to the – SER, + SER, CK and D terminals.
Telephone line connection (optional)
In the event that the control unit is equipped with a PSTN telephone interface, connect the control unit to the
telephone line according to the diagram below:
The control unit shall be the first device connected to the incoming telephone line: any other device (fax, answering
machine, telephones) shall be downstream the control unit. This type of connection ensures that the control unit will
also be able to engage the telephone line in case of need, thus leaving out all the other connected devices.
Handle the duplex cable with care, since the telephone control unit supply voltage may be live! When connecting
the duplex cable to the interface terminals LA and LB, you need not allow for polarity.
The telephone interface is equipped with a protection suitable for standard needs, as laid down by the law
regulations. In the event that you operate in a place with a great risk of electric discharge on the telephone line, an
auxiliary protection (not supplied with the unit) may be optionally installed on the telephone line, upstream the
control unit.
DECLINATORY CLAUSE
Elkron S.p.A. decline all responsibility for non-availability, either temporary or permanent, of the PSTN
telephone line, which may affect making calls and sending programmed messages.

Booster battery connection
1. Connect the two cables equipped with Faston connectors to the BATT + (red cable) and BATT – (black cable)
terminals of the control unit master card.
2. Fit in and secure the battery into the relevant control unit housing, then connect the Faston connectors to its
terminals (red = +, black = –).
2.4 INSTALLING THE KEYPAD
The KP120D keypad may be installed both on a wall and onto an embedded box with three compartments. A hole
(3) is available to let the bus cable through: in the event that the hole is not compatible with the cable run or it is not
enough (e.g. because the keypad auxiliary inputs have to be used, too), you will be allowed to open the central
break-through hole (4).
1) Wall fastening holes
2) 3-compartment embedded box fastening holes
3) Bus cable run hole
4) Cable run break-through hole
5) Tamper spring hole.
The keypad is equipped with two inputs normally closed (N.C.) to the negative for connection of other detectors
or buttons (e.g. panic button).
Reminder: for easier use, the keypad should be installed at a height of approximately 160 cm.
To install the keypad, proceed as follows:
1. open the keypad by applying a slight pressure with a single-cut screwdriver at the point shown in the figure, so
as to disengage the closing tooth.
2. If the keypad is not installed on a 3-compartment box, use a pencil to mark the positions of the fastening holes (2
holes will be enough) on the wall, then make a drill by using a bit at least 5 mm wide and fit in the dowels (the latter
need not be used on wooden walls).
3. Allow the cables to run through the keypad bottom cover.
4. Secure the keypad bottom to the wall. If you do so on a 3-compartment box, use suitable screws; otherwise use
the dowel screws. Warning!: Prior to securing, check the position of the bottom: the tamper hole shall be down.
5. Select the address by means of the keypad dip-switches:
Displaying on keypads Dip-switch
Address Keypad Input Z1 Input Z2 Tamper 1 2 3
1 Keypad 1 B1 B2 BA ON ON ON
2 Keypad 2 B3 B4 BB OFF ON ON
3 Keypad 3 B5 B6 BC ON OFF ON
4 Keypad 4 B7 B8 BD OFF OFF ON
The chosen address will also determine the input and tamper addresses. Warning!: There must not be two or
several keypads with the same address.
6. Make sure that dip-switch 4 is OFF: if it is ON, the tamper will be disabled and the IMQ certification will be lost.
7. Connect the keypad to the bus by means of terminals +, –, CK and D (refer to paragraph 1.1.2 bus for more
information), then close inputs Z1 and Z2 to the negative, if they are not used.
