DESCRIPTION
The FG-NET Digital system ensures an immediate detection and the precise location of any liquid leaks (water, acids, bases, solvents, hydrocarbons) in both industrial applications and buildings.
The FG-NET system is composed of an FG-NET Digital Unit, plus lengths of sense cables and accessories. The FG-NET Digital Unit is designed to be used with TTK digital sense cables FG-EC (water and bases), FG-
AC (acids), or FG-OD (hydrocarbons and solvents). Different types of sense cables can be connected on the same unit.
The presence of liquid on the sense cable triggers an audible alarm and activates the relevant relays. The 7 (175mm) touch screen display shows the location of the leak to the nearest metre and details of the fault in text format; an interactive installation plan (optional) highlights the location of the fault in real time.
Each sense cable comes equipped with a microchip at the female connector end. The Digital Unit questions each cable successively; the microchip then digitally transmits the state of the cable to the Digital Unit. Due to the autonomy of each cable, several faults can be detected at the same time within the same circuit.
A Digital Unit can manage three circuits of sense cables; each one of these circuits has a maximum capacity of 40 sense cables (15 metres I total), or 120 lengths of sense cable, that is 1,800 metres maximum for an FG-NET unit. In addition to the presence of liquid, the system detects and locates any faults in cable breaks within the circuit.
The FG-NET Digital Unit is available in a rack-mounted (19 and 4U in height) version (FG-NET E), or a wall mounted version (FG-NET F).
The touch-screen on the front face makes the setup of the system easy: For example, you can nominate the zones for detection (by assigning a name to each sense cable), choose and configure the set-up (relays, serial links), set the system parameters (language, time adjustment, date, user access levels, relay setup, serial link connection, etc.).
The system's reaction time to faults on each sense cable is adjustable. It is possible to remotely isolate a sense cable for up to 72 hours. The Digital Unit can store up to 5000 events in the event log.
In order to explore the fault, three types of interface with a centralized technical management system are available: TCP/IP connection via an Ethernet port; JBUS/MODBUS protocol (Serial links - RS232, RS422/485 output) and nine relays: eight of which are fully configurable and one to interrupt the power supply.

FG-NET_Operation & Installation Manual_UK_v3.1.5_201809.docx
CHAPTER II: CABLE AND ACCESSORIES INSTALLATION
The FG-NET 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. INSTALLING ADDRESSABLE SENSE CABLES
1.1. Hold-down adhesive clips
The sense cables are fixed to the earth with adhesive clips, type CF-EC100. (100 clips available per tube of adhesive).
The first stage of the installation consists of sticking these clips to the earth using the adhesive provided.
Recommendations:
1. To 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.

FG-NET_Operation & Installation Manual_UK_v3.1.5_201809.docx
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!
Pay attention to the direction of the sense cables!
The FG-CLC leader cable is connected to the FG-NET Digital Unit. The sense cable starts with a male connector, and ends with a female connector. On board electronics are located at the end of the sense cable.
1. Connect the first sense cable to the leader cable (coming from the FG-NET 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-40 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-terminated neutral Belden 8723 cable and finish the
circuit with a modular end termination plug.
1.3. Installing 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.
18
Sep 2018 – Version 3.1.5
FG-NET_Operation & Installation Manual_UK_v3.1.5_201809.docx
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. A OD end termination plug (FG-TMOD)
5. Hold-down adhesive clips (CF-OD50)
6. FG-OD kit installation instructions
Caution!
All FG-OD hydrocarbon or solvent sense cables must be installed in clean areas.
Connection with a FG-NET Digital Unit:
The set contains:
1. FG-NET Digital Unit
2. One or more Digital FG-OD kits for FG-NET (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-NET Digital Unit, follow the FG-NET installation instructions guide in chapter 1.3 of
this document. FG-NET 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
The FG-NET power supply must be switched off.
1. Connect the Belden 8723 cable to circuits 1, 2 or 3 in the FG-NET 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
19
Sep 2018 – Version 3.1.5
FG-NET_Operation & Installation Manual_UK_v3.1.5_201809.docx
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 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 drying for few hours.
Caution! All hydrocarbon sense cables must be installed in clean areas.
1.4. Labelling with tags
ES-EC and ES-OD tags indicate the presence of installed sense cables. Part of the label is intended for the user to note the distances during water leak simulations.
Fix the tags every five metres on the sense cable circuit.
Ensure the tags are clearly visible.

Heat the whole cable with a heat gun to shrink the tube. Heat it on the side of the male
connector whilst holding it down so that it remains in place. Then heat the whole of the heat shrinkable tube.
Heat it sufficiently to melt the adhesive ring until the adhesive is visible outside the tube (on
the cable side).
Caution!
Do not heat it too much, or you risk the cable overheating and melting.
