D8128D
The number of D8128D OctoPOPITs connected limits the number of D8129 Octo-relays that can be connected
to each ZONEX Terminal.
Using the D8129 Octo-relays and D8128D OctoPOPITs together on the same ZONEX Terminals is
limited and depends on the number of D8128D OctoPOPITs and D8129 Octo-relays connected to a
single ZONEX Bus. Table 4 shows the maximum number of D8128Ds and D8129s you can connect to
a single ZONEX Bus.

Installation
Before installing the D8128D OctoPOPIT, become familiar with the operation and installation guide and the
program entry guide corresponding to your system. Follow the four-step process for the most effective
installation:
•
Set the OctoPOPIT switches.
•
Mount the OctoPOPIT to the enclosure.
•
Wire the OctoPOPIT.
•
Wire the OctoPOPIT sensor loops.
3.1
Setting OctoPOPIT Switches
The D8128D has two sets of DIP switches. Use the DIP switches on
the top of the unit (with the terminal strip along the left edge) to
set the OctoPOPIT address. Use the DIP switches at the bottom of
the unit to enable or disable individual points connected to the
OctoPOPIT.
3.1.1
Address Switches
The switches on the D8128D OctoPOPIT set point assignments and
line termination (Figure 1). These switches are easier to set before
mounting the D8128D in the enclosure.
3.1.1.1 Address Assignment Switches
Switches 1, 2, 3, and 4 assign the OctoPOPIT sensor loops to point
numbers on the control panel. Table 6 on page 11 show the
OctoPOPIT switch settings for point assignments, depending on
the control panel being used.
3.1.1.2 Line Termination Switch Settings
Switch 5 sets line termination.
•
If no D8125 POPEX is connected to ZONEX 1, set switch 5 of only one D8128D connected to those
terminals to the ON position.
