3.2 Earth Fault Detection
Each NGM PCB is fitted with two jumper links,
EF1 and EF2, to enable or disable earth fault
monitoring (copper-conductor cables only) on
each inter-node link. EF1 is used with the
network link through connector J1. EF2 is used
with the network link through connector J2.
Earth fault monitoring is enabled with the link
fitted. To disable earth fault monitoring remove
the link.
Caution: To avoid an earth loop, only one
end of each network link should
have earth fault monitoring
enabled.
Network Gateway Unit (NGU)
If one of the inter-node links is connected to
an NGU it must have the appropriate EFD
jumper link fitted. This means that, in some
cases, an NGM could have both jumper links
fitted.
Note: DO NOT connect two, or more, NGUs
together as the link between NGUs
cannot be monitored for earth faults.
3.3 Cables
Conventional copper-conductor cable types
can be used for the communication link
between networked nodes.
NOTIFIER recommend the use of MICC with
a LSF PVC overcovering, a fire-resilient cable
to BS7629 or PVC/SWA/PVC to BS6387.
Alternatively, for longer inter-node distances
fibre-optic cables may be used - the optional
Fibre-optic Interface PCB (PN: 124-319)
available from NOTIFIER Fire Systems is also
required. Only one PCB is required per node.
NOTIFIER have carried out extensive cable
testing with the ID
2
net network. Applying the
following guidelines will allow networks to be
installed with cable runs of up to 2000m.
a. Test results show maximum
communication distances ranging from
1000m to 2000m.
b. Different cable cross-sections for the same
make and type of cable were found to give
almost identical results.
c. Doubling-up wires in multi-pair cables
produces shorter operating distances. It is
better to use a single pair and not use the
others to avoid cross talk.
