4- PANEL INPUTS
4.1 Mains Power Supply
The panel is designed to operate on 220 V AC 50Hz. Earth connections must be made to earth terminal and
earth resistor must be less than 10 Ohms. The mains power supply of the panel must be via an independent
self-resetting fuse rated 5A 220 V AC. This fuse must be separate from the other fuses and a caution note
should be written such as “ATTENTION! GAS ALARM CONTROL PANEL FUSE. DO NOT REMOVE”to
ensure safe operation of the panel.
Recommended cable types are 3x2.5 NYM or 3x2.5 NYA. Connections should be same as Annex.A Figure1.
Do not connect or disconnect the loop, 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 has an
automatic battery charger circuit. The panel uses 2 units of 12V DC 7Ah dry type batteries. Connection
diagram can be seen in Annex.A Figure-2.
4.3 Channel Inputs
These inputs provide power to the gas or fire detectors and transmit the status of gas/fire alarm, short circuit
and open circuit. In each channel input 4-20mA or conventional fire detector connection can be made.
4.3.1 Fire detectors and MCPs
For each zone line at most 20 units of detector and infinite number of button can be connected.
The characteristicsof the cable are dependent on the length of the loop: for a loop of 0-500 metre long, use
1x2x0.8+0.8J-Y(st)Y cable, for a loop of 500-1500 metre long use 1x2x1.5+0.5J-Y(st)Y. A 6.8 kΩresistor
must be connected as an end-of-line element.
Channel jumper setting should be set as fire. If zener barrier will use, the jumper of zener barrier must be
adjust accordingly. Connections are seen as in Annex. A –Figure-3.
4.3.2 4-20mA input
It provides 28V DC supply voltage for both fire and gas detectors. It follows 4-20 mA analogue current input
via 100 Ohms resistor. It is possible to mount 2- or 3- wire gas or flame detectors, in either sink or source
mode. Control panel can make the tracking of the analogue values between 4mA-21.5mA. When the
currents exceed 21.5 mA, panel gives the fault of “OVERRANGE”. Connection can be seen from Annex. A
figure -9.
4.3.3 Connections of 4-20mA converter card
1- The jumper settings on both converter card and gas alarm control panel adjusted as “SOURCE”or
“SINK”. The point here is both adjustments should be same.
2- Before connecting 4-20 mA card to the panel, from the panel menu, channel device type must be
selected as “det 4-20 srce” or “det 4-20 sink”.
3- Before doing the signal connection of converter card to the panel, card is energized from the panel.
4- Voltmeter’s probes, are connected to (+) and (-) supply terminals of CON1 socket go to detector. Value
seen on Voltmeter is adjusted to 2V by using TP3(detector voltage potentiometer.)potentiometer.
5- Then converter card’s energy is turned off.When all the connections are made, it is reenergized.
6- Voltmeter’s probes are connected to the test points TP4 and TP3. Value seen on the voltmeter is
brought to zero by using TP4 (balance potentiometer)O. Make sure that 0 value see continuously.
7- Voltmeter’s probes are connected to the test points TP2 and TP1. Value seen on the voltmeter is
brought to 40mV by using TP2 (zero potentiometer).
8- After these settings applied, the measured value should be read as 0.

4.3.4 Two - wire detectors
In Figure-8, Annex. A ; a sink current detector’s connection is shown. Appropriate jumper settings should
be selected.
4.3.5 Three - wire detectors
In Figure-9 Annex-A; a 3-wire detector’s connection is shown. Appropriate jumper settings should
be selected as sink or source.
4.3.6 Flame detectors
Jumper settings are adjusted according to detector is sink or source. Definitely do not select fire settings
4.4 Remote control inputs
Some of controls of gas alarm control panel can also be done remotely. These are:
· Alarm Silence / Reset - As/R: In case of alarm, to silence the sounders, switch is closed for one time.
If it is closed again, alarm situationis reset and system turns back to its initial position.
·Inhibiting All Channels - Inh: Inhibits all channels. In this case panel keeps tracking detectors. Yet, if
there is an alarm from any fire or gas detectors, it shows the situation only from LCD panel.
Connections should be as in figure- 7 Annex. A. Screening table should be used.
5- PANEL OUTPUTS
5.1 Sounder outputs
The panel has 2 sounder outputs, each rated 24V DC 500mA. Current consumption more than 500mA will
cause a fault condition in sounder line. Sounder circuits are continuously monitored for open and short
circuit faults by connecting the end of line resistor on the last device on the circuit. 2x1.5 mm²cable
should be used for cabling of sounder outputs. Connections should be made according to Annex-A
Figure-4. Polarised type sounders should be used. Otherwise, fire alarm control panel displays a fault
condition.
5.2 24V DC Power Supply (Aux) Output
The panel is equipped with an auxiliary 24V DC 500mA power supply output. The output is used to
energise external devices such as telephone dialler or gas detector. Overloading the output will cause
device malfunction or output fault respectively. Connections should be made according to Annex-A
Figure-5.
5.3 Relay Outputs
Panel has 4 volt free changeover relay outputs rated 1A at 30 V DC. These volt-free outputs, high alarm
relay (normally de-energized), low alarm relay (normally de-energized), over-range relay (normally de-
energized) and fault alarm (normally energized) relay. Connections should be made according to Annex-A
Figure-6.
5.3.1 Low alarm relay: Low alarm relay is activated when the detectors channel low limit
value exceeds in the medium. Features of low alarm relay; threshold, latching/non-latching, NO/NC
operating is adjusted by the user.
5.3.2 High Alarm relay: High alarm relay is activated when the detectors channel high limit
value exceeds in the medium. Features of low alarm relay; threshold, latching/non-latching, NO/NC
operating are adjusted by the user.
If channels include conventional fire alarm detectors, when detectors sends fire alarm signal, high
alarm relay will be activated.
5.3.3 Over-range Relay: If the gas level in the medium exceeds a fixed high limit (21.5 mA),
over- range relay is activated. Latching/non-latching,NO/NC operating is adjusted by the user.

KK-642.014 Rev.No:1 01.08.12 Page | 6
5.3.4 Fault relay: When fault condition or panel’s energy is cut off, it changes its position. When
the fault condition disappears, fault relay gets back to its initial position.
Important Note: Under no circumstances should voltage or current outside of 1A at 30 V DC used
with contacts. Otherwise, damage on panel may occur, which is not subject to maintenance under
warranty. If the relay outputs are used in an application requiring continuous high current, even
below the rated values, an appropriate contactor should be used between the device and the alarm
contacts. If not, main board of panel can blow or become damaged. Warranty excludes in this case.
