6.2 Network Connections

An ID2000 Series Network master terminal can be
networked with up to seven Network slave terminals,
master repeaters and slave repeaters to a maximum of
thirty one components.
The Network master and slave terminals use RS485
signalling to communicate with each other and with the
repeaters. The Network master terminal, slave terminals
and repeaters must be connected in a 'daisy chain'
The termination resistors must be disconnected from
all stations except the two end stations, as described
for repeaters in Section 6.1.
The ID2000 network can consist of a mixture of ID2000
panels, ID3000 panels (reduced functions), ID1000
panels, and repeaters all connected via the RS485
communication link. The following rules concerning
Earth Fault Monitoring (see Section 8.6) must be
a. The repeaters can be powered from the Auxiliary
Supply Output of the ID2000 panels without causing
an Earth Fault. However, if the repeater is powered
from an external supply then this supply must be
b. The Earth Fault Monitoring can be enabled on the
individual ID2000 and ID3000 panels on the network
but any ID1000 panel panel on the network MUST
have its Earth Fault Monitoring disabled.
c. If an Earth Fault occurs anywhere on the network
then every panel with its Earth Fault Monitoring
enabled will report the Fault.
Note: This is not true for networks that contain only
isolated RS485 connections. In this case the fault
will be localised to the faulty panel.
d. If any RS485 device other than a repeater or ID1000
panel or ID3000 panel is connected to the network, it
MUST be an isolated device.
