The FG-NET digital unit is designed to be used with all TTK digital sense cables.
In the event of a fault on the sense cables (leak or cable break):
Primary responses from the FG-NET:

• An audible alarm is triggered and a relay is activated.
• The touch screen display on the panel shows the location of the leak (to the nearest metre) and details of the fault (the type of fault leak or cable break), including the time and date the fault is registered.
• Optional – The dedicated monitoring software (TOPSurveillance) displays the dynamic drawings highlighting the location of the fault.

Secondary advanced responses:

• Report to the BMS via a JBUS/MODBUS protocol. The FG-NET can drive dynamic drawings on the host BMS.
• Send email alerts and SNMP traps to a LAN-connected BMS, via a standard Ethernet connection.

• 7” (175mm) touch screen gives a clear and detailed indication of the system status.
• User-friendly system - Users can customise the system with the sub menus accessible from the home screen, to set up system architecture, user access levels, relays, serial links etc.
• Up to 120 lengths of sense cables (or 1800 metres) can be managed independently by the unit.
• The system’s reaction time to faults is adjustable.
• Temporal isolation (72 hours maximum) of a faulty sense cable.
• Up to 5000 events stored in the history log.
• Non-volatile memory (SD card) available on the unit, for storing user settings and dynamic drawings.
• Three types of interface for communication with a BMS available.

• TCP/IP connection via an Ethernet port

• JBUS/MODBUS RS232 or RS422/485 serial links
• 9 relay contacts: 8 configurable relays and 1 specific relay for power interruption.

• Dual relay drive (e.g. 1 for BMS plus 1 for solenoid valve);
• Relay positions are defined by an LED indicator.
• Different security levels with unique passwords to provide maximum security.

• Pin-point location of a leak (to 1 metre).
• Each sense cable is addressable and can be customized by assigning a specific identity and name.
• Multiple simultaneous leaks can be detected (120 cables = 120 alarms).
• Three different types of sense cables (for detecting conductive & non-conductiveliquids) can be connected on the same panel for a truly bespoke system.
• Cable break faults can be detected (to the nearest cable).
• When a cable break occurs, the system maintains its integrity by continuing to monitor all preceding cables for faults.
• Compatible with existing monitoring systems (Trend BMS etc.)
• Extension and upgrade of the system is easy. No additional power source or zoning panels are required.
• Minimum maintenance required.
