8.2 D8125, D8127 and D9127 POPIT
Modules
D8127 and D9127 POPITs use the D8125 POPEX
Module to report to the panel. Each D8125 supports up
to 119 POPIT points. Connect two D8125 Modules to
the D9412G to bring the combined total number of
POPIT and on-board points to 246. Points 9 to 127
connect to the first POPEX Module. Points 129 to 247
connect to the second POPEX Module. The D9412G
reserves Points 128 and 248 for internal use. The panel
only annunciates activity for each POPIT, not each
detection device connected to the sensor loop.
There are two versions of the D8127 and D9127
Modules. Both module enclosures are made of UL
Listed fire resistant material. D8127T and D9127T
Modules contain tamper switches. D8127U and D9127U
Modules include untampered covers. Unless the module
is mounted in a tampered enclosure, UL requires
D8127T and D9127T Modules for certificated accounts.

Listings

The D8125 POPEX and the D8127 and D9127 POPIT
Modules are UL Listed for Local or Police Connected
Burglar Alarm, Central Station Burglar Alarm,
Household Burglar Alarm, Central Station Fire, Local
Fire, Remote Station Fire, Household Fire, and

Installing the D8125 POPEX Module

For information on the Multiplex Bus
Interface, see the D8125 Multiplex Bus
Interface Operation and Installation Guide.
Save the POPIT Label Sheets: The D8125 is packaged
with two sets of POPIT label sheets. One is marked for
use with the D9412/D9112. Save this set for use with the
D9412G/D7412G; it is used later to label the POPITs.
8.3. 1

Mounting

To install the D8125 in the enclosure with the panel:
1. Align the D8125 POPEX Module with any of the
four mounting locations in the enclosure
(see Figure 2).
2. Using the screws provided with the module, secure
it in the enclosure.
8.3.2

Wiring the D8125 to the Control Panel

To wire one or two D8125 Modules to the panel (see
Figure 14 and Figure 15):

8.0 Off-Board Points
Power Down First: Power down the panel by
disconnecting the positive (red) battery lead at the
battery and unplugging the transformer.
For Points 9 to 127 (9 to 75 on D7412G):
1. Connect the GND terminal of the D8125 to
Terminal 23 on the D9412G or to Terminal 9 on the
D7412G.
2. Connect the OUT terminal of the D8125 POPEX
Module to ZONEX IN 1, Terminal 27.
3. Connect the IN terminal of the D8125 POPEX
Module to ZONEX OUT 1, Terminal 28.
4. Connect the AUX terminal of the D8125 to
Terminal 24 on the D9412G or to Terminal 3 on the
D7412G.
For Point numbers from 129 to 247 (D9412G only):
1. Connect the GND terminal of the D8125 to
Terminal 23.
2. Connect the OUT terminal of the D8125 POPEX
Module to ZONEX IN 2, Terminal 25.
3. Connect the IN terminal of the D8125 POPEX
Module to ZONEX OUT 2, Terminal 26.
4. Connect the AUX terminal of the D8125 to
Terminal 24.
See Section 8.3.4 Wiring Data Expansion Loops to POPEX
Modules for instructions on connecting POPITs to the
D8125 POPEX Module.
8.3.3

Wiring POPITs to the Data Expansion Loop

Use one 2-wire data expansion loop or distribute the
POPITs on up to three loops. Setting DIP switches on
the POPIT Modules assigns them to point numbers. See
Section 8.3.6 POPIT Module Point Assignments.
Review Section 3.6.2 Install and Wire Detection Devices to
determine if shielded wire is required. Determine the
required wire gauge for the length of each data
expansion loop using Table 12.
