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 Guide 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 Bosch Security Systems' panels shown in Table 3. (Also shown are previously
manufactured D8128 OctoPOPIT Modules.)

10.2 VDC to 13.8 VDC, supplied by the panel
51 mA per OctoPOPIT module (all points shorted @ 13.8 VDC)

+32°F to +120°F (0°C to +49°C)
1 kΩ (+/-100 Ω)
Approximately 1 second. OctoPOPIT sensor loops are supervised with a 1 kΩ
end-of-line resistor: Bosch's D105BL or D105FL (for fire supervisory
applications)
Burglary applications: D8128D OctoPOPITs may be installed up to 200 ft.
(61 m) from the control panel using standard 4-conductor 22 AWG (0.8 mm)
wire. Shielded cable is recommended when the D8128D is located outside the
control panel enclosure.
Fire applications: UL Listed fire-rated cable approved by the AHJ must be used
when connecting fire-initiating or fire-supervisory devices to the D8128D.
D8128D Octopopits may be located up to 200 ft. (61m) maximum from the
control panel and must be mounted in a D8109 or D8108A enclosure. If a
D125B Dual Powered Loop Interface Module or D129 Dual Class A Module is
required, they must also be mounted in the same enclosure as the D8128D
Octopopit.
Each OctoPOPIT uses 51 mA (worst case). This affects the number of units that
can be connected on a single wire run.
