D8128A OctoPOPIT Module
Description
The D8128A OctoPOPIT Module combines the functions of the D8125 POPEX module
and the D8127 POPIT modules to provide eight off-board points in a single module. You
can use OctoPOPIT and D8125 POPEX modules on the same D9112.

Warning, Do not use D8128 modules, they are not compatible with the D9112, only

use D8128A modules:

Using D8128 modules may cause intermittent missing and
restoral reports. Be sure to only use D8128A modules.
Review the

Power Outputs

section of this manual to be sure you provide enough power
for the OctoPOPITs and other powered devices you wish to connect to your system.

Do not use the instructions packaged with the OctoPOPIT:

The literature packaged
with the OctoPOPIT is not for use with the D9112 panel. Use the instructions below.

Listing

The D8128A OctoPOPIT Module is UL listed for Local or Police Connected Burglary
Alarm, Central Station Burglary Alarm, and Household Burglary Alarm applications. The
D8128A is also suitable for fire supervisory applications, such as indicating circuit
supervision (using the D192A Bell Circuit Supervision Module), sprinkler supervision, and
valve tamper protection. Do not connect fire alarm initiating devices to the D8128A
You must use the D125B Powered Loop Interface Module or D129 Dual Class A initiation
Circuit Module for fire initiation applications. Connect the initiating devices, smoke
detectors for example, to the D125B powered loops or D129 Class A loops.
Connect the zone outputs on the D125B or D129 to the OctoPOPIT sensor loop inputs.
The D125B or D129 and the OctoPOPIT must be mounted in the enclosure with the
D9112 or in an enclose connected to the D9112’s enclosure by conduit not more than 20
feet in length.

Installing the OctoPOPIT

You can install the D8128A OctoPOPIT Module in the enclosure with the D9112, or in a
separate enclosure up to 200 feet from the panel. If you mount the OctoPOPIT in a
separate enclosure, use shielded cable to avoid electro-magnetic interference. See

EMI

on Long Wire Runs

in the

Troubleshooting

section of this manual.

Tampered enclosures for UL certificated systems:

Mount the D8128A in a tampered
enclosure for UL certificated systems.
Mounting
Follow the procedure below to install OctoPOPITs in the enclosure with the D9112.
1. It is easier to set the switches on the D8128A before you mount it in the enclosure.
See

Line Termination, Sensor Loop Switches,

and

Point Assignment Switches.

2. Align the OctoPOPIT module with any of the four mounting locations in the enclosure.
See Figure 2.
3. Use the screws provided with the module to secure it in the enclosure.
Use the D137 Mounting Bracket to install OctoPOPITs in enclosures with no module
mounting locations available.
