ID3000 Series Installation & Commissioning Manual
2.1 Network Topology
Fire control panels MUST be networked as a
complete and continuous loop. A typical
arrangement is illustrated at left.
Each ID
net Network Gateway Module (NGM)
2
(Kit PN: 020-647) can be used with any of the
following network cable options:
a. Conventional, copper-conductor cables
b. Optical-fibre cables
c. A mixture of conventional and optical-fibre
cables.
The ID
net Network PCB is provided with two
2
wiring connectors, J1 and J2 (located along
the top edge of the PCB) for data
interconnection with other panels using
conventional cables (see example A at left).
A ribbon-cable connector, J3, provided on the
left-hand edge of the Network PCB is used for
connection to an optional Interface PCB (Kit
PN: 020-643) when optical-fibre cables are
used (see example B at left).
If required, the use of a mixture of conventional
and optical-fibre cables at each node can be
supported (see example C at left).
