Installation

For the most effective installation, use the following
four-step process:
1. Set the OctoPOPIT switches. Refer to Section

9.4.4 Setting the OctoPOPIT Switches.

2. Physically mount the OctoPOPIT in the
enclosure. Refer to Section 9.4.5 Mounting
OctoPOPITs on page 39.
3. Wire the OctoPOPIT. Refer to Section 9.4.6
Wiring OctoPOPITs on page 39.
4. Wire the OctoPOPIT sensor loops. Refer to
Section 9.4.6 OctoPOPIT Sensor Loops on page
42.
9.4.4 Setting the OctoPOPIT Switches
The D8128D OctoPOPIT has two sets of DIP
switches (Figure 15). Use the DIP switches on the top
of the unit (with the terminal strip along the left edge)
to set the address for the OctoPOPIT. Use the DIP
switches at the bottom of the unit to enable or disable
individual points connected to the OctoPOPIT.
Address Switches
The switches on the D8128D OctoPOPIT set point
assignments and line termination. These switches are
easier to set before mounting the D8128D in the
enclosure.
Switches 1, 2, 3, and 4 assign the OctoPOPIT sensor
loops to point numbers on the control panel. Table 13
shows the OctoPOPIT switch settings for point
assignments.
Switch 5 sets line termination. Refer to Table 14.
