2- WARNINGS

The panel contains static-sensitive high quality electronic control equipment. Do not use the
panel before reading this manual.

In case of any fault, only the technicians of the manufacturer or technicians authorized by the
manufacturer should repair or maintain the panel.

The person who will operate the system should be well trained on powering and operating the
system.

Two years of warranty is valid from the production date as long as the system is used with
regard of obeying the rules, instructions and recommendations provided by the manufacturer.

Use the recommended cable types defined in this manual for cabling of panel power supply,
sounder power supply and detector line. Do not remove any connections and do not make any
connections while mains power supply is connected. Panel’s earth connection must be made
definitely.

Do NEVER apply 230V AC 50Hz mains power into the detectors and manual call points input
terminals, sounder line outputs and battery connection inputs.

This panel has been designed to operate on 230 V AC 50 Hz power supply. The protective
earth connection must be made definitely and the mains power supply must be presented
through the device via a fuse assigned only to this device. If the earth connection is not made
appropriately, all the conductive parts in the device may result in electrical leakage and this
may create hazard.

‘Automatic Learning’ causes erasing of existing configuration data at the panel. Therefore, it is
recommended to download the configuration data to PC, before ‘Automatic Learning’.

3- MOUNTING

The chosen mounting site of the panel must be clean, dry, not subject to shock or vibration
and easily accessible. The temperature must be in between the temperature range of

-5C° and +50C°. The relative humidity must not be m ore than 95%.
The panel should be mounted on a flat surface in such a way that, the indicators should be at

the eye-level and must not be mounted near the sources of excessive heat or cold and inside
of any cabinet.

Uncover the panel via the allen key provided with the panel.
Panel cable entries from back and top of the panel are available for easy mounting. Mark the

position of the fixing holes according to the respective Annex-A, Figure-2; ensuring that the
wall is flat at the chosen location.

Screws or bolts of a minimum of 4mm diameter must be used to mount the cabinet in all four
mounting positions. Drill and plug the wall then fix the cabinet using all fixing points.

4- PANEL INPUTS

4.1 Mains power supply

The system is designed to operate with 230V AC 50Hz. Earth connections must be made to
earth terminal and earth resistor must be less than 10Ω. The mains supply of the panel must
be via an independent self-resetting fuse rated 230V AC 6A. This fuse must be separate from
the other fuses and a caution note should be written such as ‘ATTENTION! FIRE ALARM
CONTROL PANEL’S FUSE. DO NOT REMOVE’ to ensure safe operation of the panel.
Recommended cable types are 3x2,5 NYM or 3x2,5 NYA. Connections must be done
according to Annex- B, Figure-1.

Do not connect or disconnect loops, mains supply input and PCB connections while the panel
is energized, to avoid an electric shock.

4.2 Batteries

Batteries provide continuity of operation during a failure of the mains power supply. The panel
uses 2 units of 12 V DC 7Ah dry type batteries. Battery connection scheme can be seen from
Annex-B, Figure-14.

4.3 Detection Devices Inputs (Loop Lines)

ML-121X series panels are produced with 0, 1, 2 loop models. Panels with
0 loops (no-loop) are used as repeater panels. Each loop is capable of hosting up to 127
addressable devices. Connection of loop line to the control panel must be as like in Annex-B,

Figure-7. A 0Ω resistor must be connected to the unused loops. Each device in the loop must
be addressed via MG-8200 Address Programmer depending on the architectural project of the
site.

The semi-duplex two-wire digital serial synchronous communication between the devices
connected to the loop and the fire alarm control panel is established by the VIP
communication protocol.

Short circuit isolators must be placed in such a way that more than 20 detectors and/or
manual call points shall not be out of service in case of any short circuit occurrence in the
loop.

The devices should be connected to a one-pair cable to create a loop and should turn back to
the panel from the last device.

The loop is energized from the ‘out’ terminal of the panel and the turn back point toward the
panel is the ‘in’ terminal. In case of rupture or short circuit, the loop is energized from both the
‘in’ terminal and the ‘out’ terminal. Thanks to this functionality; it is provided that the devices,
except from the detectors / buttons which are in failure, go on functioning properly while the
part in failure is isolated.

It should be used the short circuit isolator for each ‘in’ and ‘out’ terminals. Thus, if any problem
occurs in between the part from any of the ‘in’ or ‘out’ terminals to the first short circuit isolator
location, this part is isolated and the rest of the loop can go on functioning properly.

KK-641.002 Rev.No:1 01.08.12 ML-121X User Manual Page | 6

1x2x1,5+0,8J-Y(st)Y, 1x2x0,8+0,8J-Y(st)Y or 1x2x1,5+0,8J-H(st)H, 1x2x0,8+0,8J-H(st)H
coded cables should be used. While cabling (starting from Loop + terminal), cable’s earth line
must be connected to appropriate earth terminal in the control panel (See Annex-B, Figure-2).
This earth line should be installed throughout all detectors and call points. Earthing cables
should be wired after placing detectors and/or call points and line should be ended. When a
return is performed to (Loop -), earthing line should be done as it is shown in Annex-B,
Figure-2 and line is ended.

4.4 Panel PC Connection

4.4.1 PC Port
Cable connection between panel and PC for data communication is plugged into the PC

Socket which found on front panel of (See Annex-B, Figure-11). The communication cable
shown in Annex-D must be used for communication with computer.

4.4.2 Write Enable Switch
Write enable switch has two positions as “ON” and “OFF”. (Annex-B, Figure-8) When the

panel is energized while the switch is OFF, the panel runs previously saved data. When the
panel is energized while the switch is ON, panel operation modes appears on the screen.
More details are provided in Section-8.

4.5 Remote Control Inputs
There are remote control inputs on the panel which are likely to control the panel remotely by

the help of any remote button. One terminal of the button is connected to the desired input
and other one is connected to GND. (See Annex-B, Figure-6). It should be used the cable with
this code; 2x1,5 N2XH or 2x1,5 NYY for remote control input line.

AL : Reactivates alarm condition, sounders and relays which was silenced and positioned
by Silence Alarm.

FLT : Activates fault condition.
RS : Resets the panel.
SIL : Silences sounders and returns the relays to their initial position.

5- PANEL OUTPUTS

5.1 Sounder Outputs (4 Units)

The panel has 4 sounder outputs rated 24 V DC 500mA. In order to monitor the line against to
open or short circuit conditions, normally 16 V DC reverse voltage is seen from the sounder
outputs. During fire alarm outputs are driven by 24 V DC (Annex-B, Figure-4). Current driven
more than 0.5A leads the panel into the fault condition.

2x1,5 N2XH or 2x1,5 NYY cable should be used for the sounder line. 10KOhm resistor,
located on sounder outputs from factory default is used as end-of-line resistor and must be
connected to the end of the sounder line. Otherwise, open circuit fault is monitored on the
sounder line of panel. In case of any open circuit or short circuit faults occurred, it can be
displayed on the screen of panel with the line number.

KK-641.002 Rev.No:1 01.08.12 ML-121X User Manual Page | 7

5.2 Auxiliary Power Supply Output (24 V DC)

The panel is equipped with an auxiliary 0.5А 24 V DC power supply output. Exceeding this
level causes fault condition. It can be used for supplying power to peripheral devices.
2x1,5 N2XH or 2x1,5 NYY cables should be used for external power supply line. In case of
mains power supply failure, the batteries provide power supply to the output (24 V DC).
(Annex-B, Figure-3).

5.3 Relay Outputs (3 Units)

The panel has 3 units of relay outputs with volt free changeover contacts rated 1A 30 V DC.
These volt-free outputs; fire relay (normally non-energized), alarm relay (normally non­energized) and fault (normally energized). (Annex-B, Figure-5). 2x1,5 N2XH or 2x1,5 NYY
cable should be used for relay output line.

5.3.1 Fire Relay : The output is activated on any fire event and it can be used to trigger
any other system. The output is returned to its initial position only by pressing ‘Reset’ button
on panel.

5.3.2 Alarm Relay : The output is activated on any fire event and it can be used to activate
any other system. The output is returned to its initial position only by pressing ‘Alarm Silence’
button on panel. If a new alarm occurs, Alarm relay reactivates.

5.3.3 Fault Relay : The output is activated on any fault event, changes its contact in case
of mains failure. The output returns to its initial position, if fault condition is removed and the
‘Reset’ button on the panel is pressed.

Important notice : Fire alarm panel relays operate as signal-based relays. If these relays
will activate any other devices as like control relays, then a contactor should be used between
the relay and device. In case of high current driven applications, the relay outputs can get
damage if there is no contactor. This situation is not subjected to the warranty condition.
