UIDELINES
●
IEE regulations. All installations should comply with
IEE wiring regulations regarding the safety and
separation of low voltage cable from mains cable.
●
Powering devices. Rather than powering external
devices such as sounders and strobes from the
controller (which is not recommended), use
Europlex or other approved power supply units.
●
Switched loads. Devices such as strobes, bells, and
sirens should be powered on a separate cable to the
Ringnet. They should have their power provided
from local monitored power supply units, with I/O
node outputs driving the local trigger.
●
EOL resistors. The 3GS system uses two 2k2 (US:1k
and 470) end-of-line resistors per zone.

Environmental conditions
●
Temperature. 3GS is built to operate in ambient
temperatures in the range -10° to +40°C. Maximum
relative humidity (non-condensing) of 90%.
Ringnet
When wiring the 3GS system network (ringnet), ensure
the correct cable type for the system is used.
There are several factors which govern the selection of
the cable to be used.
Ringnet Speed
3072 kilobaud per second
●
Environment - When the 3GS is to be used in a noisy
environment (high power output devices, mains
cables, or high voltage devices in close proximity),
then Europlex recommend the use of high grade,
screened twisted pair cable, such as Belden 9829 or
equivalent.
●
Distance - When the distance between nodes
increases, then the grade of cable used should also
be increased as per the cable table below.
Note
The cable distance specified here is the
distance between nodes on Port 1A 1B and Port
2A 2B.
●
Screen - If screen cable is used, all screens should be
linked together and wired to the terminal provided
at the node/controller.
●
Branch Node - Each node on the system has two
drivers on board for the network, Port 1A 1B and
Port 2A 2B to achieve these distances. However,
when using the node as a branch node, there are no
drivers on Port 3A 3B and Port 4A 4B, which must
be accounted for when calculating cable distances.
