Refer to Address Switches in Section
9.4.4 Setting the OctoPOPIT Switches
on page 47 for information about
making these switch settings. Refer to
Table 13 on page 48 for information
about setting Switch 5.
For system supervision, do not use
looped wire terminals. Break the wire
run to provide supervision of the
connections.
Using Interconnect Wiring
Each D8128D Module is supplied with a 30 cm
(12 in.) female-to-female interconnect wiring
assembly.
P1 and P2 are interconnect wiring connectors
that parallel the COM, IN, OUT, and +12.0 VDC
terminals on the terminal strip. In installations
with multiple D8128Ds, use these connectors
(as opposed to terminals) with the supplied
cable; however, when connecting D8128D
Modules directly to the control panel, the
terminal strip is easier to use.
The interconnect wiring connectors provided
are "keyed" (interconnect wiring plug can fit in
only one direction). Ensure that the connector
is attached correctly: the red wire is on the
bottom of P1 (or P2) and the black wire is on
the top.
When connecting multiple D8128Ds to a
control panel, you can connect the control
panel terminals to P1 or the COM, IN, OUT,
and +12V terminals on the first D8128D. Then
connect P2 of the first D8128D to P1 of the
second D8128D and so on (Figure 19).
