D8128D Overview
2.1
Specifications
Operating Voltage
10.2 to 13.8 VDC supplied by the panel
Current
51 mA per OctoPOPIT module (all points shorted @ 13.8 VDC)
Sensor Loop Response Time
Approximately 1 second. OctoPOPIT sensor loops are supervised with a
1k
Ω
end-of-line resistor: Radionics model #D105BL or #D105FL (for fire
supervisory applications)
Cabling
D8128D OctoPOPITs may be installed up to 200 feet (61 meters) from
the control panel using standard 4-conductor 22 AWG (0.8 mm) wire.
Each OctoPOPIT uses 51 mA (worst case). This affects the number of
units that can be connected on a single wire run.
Resistance
Maximum loop resistance: 1 k

±
100
Ω
(with 1 k

Module Description
The D8128D OctoPOPIT Module combines the functions of the D8125 POPEX module and the D8127/D9127
POPIT modules to provide eight off-board points in a single module. You can wire both D8128D OctoPOPIT and
D8125 POPEX modules in parallel to the ZONEX Bus terminals on the same panel.
Review the
Power Outputs
section of your panel’s
Operation and Installation Manual
to be sure you provide
enough power for the OctoPOPITs and other powered devices you wish to connect to your system.
The D8128D is designed for use with the Radionics’ panels shown in the table below. (Also shown are previously
manufactured D8128 OctoPOPIT Modules.)

Note
:
As shown in the table above, D8128A OctoPOPITs cannot be used on the new D7212, D7412, D9112, or D9412
Control Communicators. However, D8128D OctoPOPITs may be used and intermixed with D8128A OctoPOPITs
on the D7212B1 and D9112B1 Control Communicators.
