Model IFP-2000/ECS Installation Manual
to network the panel, its DIP switches 8, 9, and 10 must be ON. Otherwise, DIP switches 8, 9 and 10 are
always OFF.
2. Jumper J1 on the network repeater is always CLOSED. Newer designs have this jumper permanently
CLOSED. On older designs you had to physically install the jumper CLOSED.
3. Jumpers J2 and J3 for the network repeater should be present (jumper is CLOSED) only when a twisted pair
is connected to Port 1 of terminal block TB1. Jumpers J2 and J3 are used to enable earth ground fault moni-
toring at Port 1 of terminal block TB1.
4. It is a requirement that an insulated wire be run between the network repeater terminal G (TB2) and an earth
grounding screw at the control panel for all network repeater installations.
The following text details how the panel and repeater terminators must be set
for the network example in Figure 5-9 on page 8.
Panel 1 is at the end of a direct connect BUS and it does not have a repeater, so its DIP switches 8, 9 and 10 must
be ON to provide direct connect BUS termination.
Panel 2 is NOT at the end of a direct connect BUS so its DIP switches 8, 9 and 10 must be OFF.
Note: A repeater would not be allowed to be connected to panel 2 in this example because it is not at the end of
a direct connect BUS.
Panel 3 looks like it is at the end of a direct connect BUS, but because it has a repeater connected to it, DIP
switches 8, 9 and 10 at panel 3 must be OFF. The direct connect BUS termination is provided by the repeater
through jumper J1. Recall that jumper J1 must placed (CLOSED) as this is the rule for ALL repeaters. Jumpers
J2 and J3 on the repeater of panel 3 must be OPEN because no wires are connected to the repeater twisted pair
terminals 1 and 2 of TB1.
Panel 4 is not directly connected to other panels but it is effectively direct connected to its repeater which
electrically behaves the same as a direct connected BUS between panels. Because panel 4 is connected only to its
repeater its DIP switches 8, 9 and 10 at panel 4 must be ON to provide direct connect BUS termination. Jumper
J1 of the repeater must also be placed (CLOSED) to provide the other direct connect BUS termination and
because the rule for repeaters is that Jumper J1 must always be placed (CLOSED). Repeater jumpers J2 and J3
must be placed (CLOSED) because a wired twisted pair is connected to terminals 1 and 2 of TB1. Connecting
these jumpers enables earth ground fault monitoring of the twisted pair wire between the repeater of panel 4 and
panel 3.
Panel 5 is at the end of a direct connect BUS so its DIP switches 8, 9 and 10 must be ON to provide the direct
connect BUS termination.
Panel 6 looks like it is at the end of a direct connect BUS, but because it is also using a repeater its DIP switches
8, 9 and 10 must be OFF. In this example, panel 6 is actually in the middle of a direct connect BUS between
panel 5 and the repeater of panel 6. Jumper J1 of the repeater is placed (CLOSED) and provides the termination.
Jumpers J2 and J3 for the repeater must be OPEN because no wires are connected to the twisted pair Port 1 of
TB1.
