DESCRIPTION
The FG-SYS Digital system ensures an immediate detection and a precise localization of any liquid
leak (water, acids, bases, solvents, hydrocarbons) in industrial applications and buildings.
The system is composed of a FG-SYS Digital Unit, lengths of sense cables and accessories.
The FG-SYS Digital Unit is designed to be used with sense cables FG-EC (Water and Bases), FG-AC
(Acids), or FG-OD (Hydrocarbons and Solvents). The presence of a liquid on the sense cable starts an
audible alarm, as well as a luminous alert. The information of the fault is displayed on the LCD screen,
which specifies the localization of the initial leak point to the nearest meter.
Each sense cable is equipped with a microchip at female connector end. The digital unit questions
successively each cable; the microchip then transmits numerically ' the state ' of the cable to the digital
unit. Because of autonomy of each cable, several faults can be detected at the same time (but only
one fault per cable).
A digital unit can manage three circuits of sense cables; each one of these circuits has a maximum
capacity of 40 sense cables of 15 meters, or 600 meters maximum per circuit. In addition to the
presence of a liquid, the system detects and locates any fault of cable break on the circuit of cables.
The FG-SYS Digital Unit is available in rack-mounted version (FG-SYS E), or wall mounted version
(FG-SYS F), with a metal enclosure.
The keyboard (of thirteen buttons) on the front face makes it possible to configure the system:
Nominate the zones for detection (by allotting a name to each sense cable), choose and configure for
the set-up (relays, serial communication), setting the parameters of the system (language, adjustment
of the time, date, protection code).
The green luminous witness, or red, indicates the state of the digital unit under surveillance mode or
alarm. The button on the right (ECS) allows the manual acknowledgement of the sound alarm, the
validation of an operation, and the return to the previous screen. The last thirty defects are kept in
memory and their description is accessible in the historical menu.
FG-SYS also has a general test function. The Digital Unit indicates the number of sense cables
installed on a circuit, the length of each sense cable, the nominated zones, associated sense cables,
as well as the overall length installed.
In order to explore the fault information, several tools are available. The FG-SYS digital unit is
equipped with eight configurable dry contacts: the choice of dry contact is associated with a cable and
the type of fault (leak, discontinuity, or both). Two independent serial links of type RS232/RS485, with
a JBUS/MODBUS communication protocol, are used for the connection to a supervisor.

II SENSE CABLE AND ACCESSORIES INSTALLATION
FG-SYS System is modular. All the sense cables and accessories are pre-terminated with both male
and female connectors. This makes the installation quick, easy, and safe.
We recommend drawing a precise map of all zones to be fitted with sense cables, ensuring that all
installation zones are clean and dry before installation.
1. SENSE CABLE INSTALLATION
1.1 Installation: Hold Down Clips with Adhesive
The sense cables are fixed on the ground by fixing clips, type CFC-100.
The first stage of the installation consists in sticking these clips on the ground using the provided
adhesive (3M cold Glue).
Recommendations:
1. Ensure the cable sticks correctly to the earth, alternate the direction of the clips on the earth.
2. The clips must follow the drawing of the sense cables and be spaced approximately 1 metre apart.
3. Wherever there is a curve of the trajectory, stick 1 clip the entry point and a second at the exit point
of curve.
4. Please wait for the clips to be completely dry (three to four hours), before installing the sense
cables.
5. When fixing the sense cables into the clips, keep a length of approximately 10 cm between the
connector and the clip.
Hold Down Clips with Adhesive (ref.: CFC-100)

10
1.2 Installing sense cables: FG-EC, FG-AC and FG-ECX
Unroll the entire length of the sense cable and place in the clips fixed on the floor before
installation.
Caution: Start with the right way of the sense cables installation.
The FG-CLC leader cable, connected to the FG-SYS Digital Unit with a female connector, at its
extremity. The beginning of the sense cable thus corresponds at its extremity with a male
connector.
1. Connect the first sense cable to the leader cable, coming from the FG-SYS Digital Unit
2. It is recommended that you avoid placing the cables in direct contact with the jacks (on the raised
floor), the cable trays, any other obstacles...
3. Take care to circumvent the air-conditioning system (at a distance of approximately 50 to 75 cm), to
avoid false leak alarms related to harmless water projections.
4. All partitions must be fitted with pre-determined neutral Belden 8723 cables: type FG-NC (1 or 3
metres).
5. Once the sense cables are fixed with clips, their length must be maintained along the flooring or
ceiling in a closed retention tray, etc…
6. ES-EC tags must be placed along the length (packet of 40 tags) and spaced approximately every 4
metres.
7. Place a new length of sense cable (a pre-termined neutral Belden 8723 cable and finish the circuit
with a modular end termination plug.
1.3Installing hydrocarbon and solvent sense cables: FG-OD
DESCRIPTION
The Oil & Gas FG-OD detection cable from TTK allows for the fast detection of any leaks of
hydrocarbon liquids. The presence of a real liquid leak, hydrocarbon or solvent, activates an audible
alarm, and detailed information is displayed on the Digital Unit with the hour, date, and type of fault:
leak or cable break. The dry contact related to the fault switches to the alarm position. This dry contact
makes it possible to drive an external alarm and be reported to a management team via BMS, remote
monitoring, solenoid valve, etc...
The dry contact remains activated as long as the alarm is present. Once the alarm has been cleared,
the relay returns to its initial position.
Due to ATEX regulations, FG-OD cables are using a different communication protocol, and they must
be connected to the system through a bus interface box FG-DOD. Up to 10x FG-OD cables can be
connected to one FG-DOD box.
The FG-OD kit contains:
1. A OD bus interface box for up to 10x FG-OD (FG-DOD)
2. A length of FG-OD sense cable (3, 7 or 12m)
3. A OD leader cable (FG-CLOD)
4. An OD end termination plug (FG-TMOD)
5. Hold-down adhesive clips
6. FG-OD kit installation instructions
CAUTION: All hydrocarbon sense cables must be installed in dry and clean areas
On the basis of the FG-SYS Digital Unit, unroll the lengths of sense cable while placing them in
the clips fixed on the ground.
Connection with a FG-SYS Digital Unit:
The set contains:
1. FG-SYS Digital Unit

11
2. One or more Digital FG-OD kits for FG-SYS (up to 40x FG-OD cables per circuit)
3. One or more additional FG-OD sense cables (max 10 FG-OD per FG-DOD)
To connect the FG-SYS Digital Unit, follow the FG-SYS installation instructions guide in chapter 1.3 of
this document.
FG-SYS haves a capacity of 40x FG-OD cables per circuit. Those cables must be connected to the
panel through a FG-DOD bus interface by groups of ten cables maximum.
Example: 4x FG-DOD with 10x FG-OD cables each = 40x FG-OD
Or: 8x FG-DOD with 5x FG-OD cables each = 40x FG-OD
Or: 2x FG-DOD with 10x FG-OD cables each + 4x FG-DOD with 5x FG-OD cables each = 40x FG-OD
CAUTION: The FG-SYS power supply must be switched off.
1. Connect the Belden 8723 cable to circuits 1, 2 or 3 in the FG-SYS Digital Unit:
On circuit no.1:
Green wire: Point 1A
White wire: Point 1B
Black wire: Point 1C
Red wire: Point 1D
2. Connect the other end of the Belden jumper cable to the INPUT points of the first FG-DOD interface
box.
3. Take the FG-CLOD 3.5 m leader cable and connect it to the following points of the ‘OD BUS’
terminal of the first FG-DOD interface box:
White wire: Point B
Black wire: Point C
Red wire: Point D
4. Fix the provided hold-down clips (1 clip per meter) and place the FG-OD sense cable in the clips.
5. Connect the FG-OD cable to the FG-CLOD leader cable, then add a second, third… FG-OD cable
(10x max) and put the FG-TMOD end plug at the end of the last FG-OD cable.
6. 7. Pour some light Naphta on the cable to simulate a leak alarm.
7. ‘OUTPUT ’ is reserved for the neutral cable going towards the next detection zones.
8. Proceed as with stage 2 for the second (and third etc.) FG-OD kits.
9. Note: on the last FG-DOD diversion box, a bridge must be installed on the unused ‘OUTPUT ’
terminal between points A and B.
OPERATION AND MAINTENANCE
The FG-OD sense cable is insensitive to the limited presence of conducting liquids (water, bases or
acids); FG-OD is also insensitive to any residual traces (lower than 35 ml) of non-conducting liquids
(hydrocarbons or solvents). The sense cable absorbs this limited presence of liquid and does not
react.
In the presence of a quantity (at least equal to 50 ml) of non-conducting liquids (hydrocarbons or
solvents), the FG-OD sense cable activates an alarm on the Digital Unit.
FG-OD cables are reusable after a limited contact with hydrocarbons. Immerse the cable in light
Naphta during 30 minutes, then remove and allow to dry for few hours.

12
1.4 Labeling with ES-EC tags
Labels ES-EC indicate the presence of sense cables installed. Part of the label is reserved to the user
to note the distance rose, during water leak simulations.
1. Fix the labels every four meters on the circuit of sense cables.
2. Ensure itself of the good visibility of the labels.
Pack of 40 Tags, ref. : ES-EC

13
2. FG-NC JUMPER CABLE INSTALLATION
It can be necessary to use jumper cable for:
Pass from a zone of detection to another
Connect the Digital Unit to the first length of sense cable
Pass through rooms...
Note: for the passages of rooms, stop the passage of the sense cable with a product adapted to the
regulation and the architecture of your customer (partition firebreak, for example).
For a correct operation of the system, you have to use the following jumper cable:
BELDEN 8723 (LSZH, if required)
This jumper cable must be equipped with a male and female connector, in order to be compatible with
the TTK sense cables. The FG-NC Kit includes for this purpose the following material:
A male connector with its 4 contacts
A female connector with its 4contacts
2 heat-shrinkable sleeves
2 rings of hot melt
Notice for the realization of the jumper cable
Tools necessary:
Material to be stripped
Air Gun, with 800W power
Flat-nose pliers
Jumper Cable Connexion
The random jumper cable is installed. The beginning of the cable is the end coming from the digital
unit. Always start by making the connection at the beginning of the cable. The beginning of each
cable must be provided with a male connector and the end of the jumper cable with a female
connector.
At the beginning of the Belden jumper cable:
