Note: As shown in Table 3, D8128A OctoPOPITs cannot be used on the new D7212, D7212G, D7412, D7412G, D9112,
D9412, or D9412G Control Panels. However, D8128D OctoPOPITs may be used and intermixed with D8128A
OctoPOPITs on the D7212B1 and D9112B1 Control Panels.
The maximum number of D8128D Modules that can be connected to your system depends on the control panel being
used (see Table 4). Please refer to Table 7 through Table 10 for proper switch settings.
The number of D8129 OctoRelays that can be connected to each Zonex terminal on the D9412G panels is limited by the
number of D8128D OctoPOPITs connected.
Using D8129 OctoRelays and D8128D OctoPOPITs together on the same Zonex Terminals is limited and
depends on the number of D8128D OctoPOPITs and D8129 OctoRelays connected to a single Zonex Bus.
Refer to Table 5 for information on the maximum number of D8128Ds and D8129s that may be connected
to a single Zonex Bus.
