TTK FG-SYS - Sense Cable Installation

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.
1.3 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.
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.
