The D8128D OctoPOPIT module combines the
functions of the D8125 POPEX module and the D8127
and D9127U and D9127T POPIT modules to provide
eight Class B (Style B) off-board points in a single
module. The D8128D OctoPOPIT and D8125 POPEX
modules can be wired in parallel to the ZONEX Bus
terminals on the same panel.
System overview
The module can be installed inside the enclosure of
the control panel, or the module can be installed in a
separate enclosure and connected to the control
panel.
Functions
Address Switches
There is a set of DIP switches for setting point
assignments and line termination. Switches 1 to 4
assign the sensor loops to point numbers on a
compatible control panel. Switch 5 sets the line
termination.
Point DIP Switches
Activate or deactivate each point connected to the
module by placing its respective DIP switch in the
closed or open position. The point DIP switch can be
used to deactivate conflicting points.

Connection Considerations
If the module is installed in a separate enclosure, it
can be placed up to 60 m (200 ft) from the control
panel:
Maximum Wire Impedance: 4 Ω
Distance (maximum) Wire Size
60 m 0.6 mm
60 m 1.0 mm
200 ft 22 AWG
200 ft 18 AWG
The module can be wired to the control panel using
the module's terminal strip or using Molex connectors.
The Molex connectors are useful when multiple
D8128D modules are in use. The terminal strip is
easier to use in cases when the module is connected
directly to the control panel.
