The control panel uses point programming to interpret the sensor loop information reported by the POPITs and
make the appropriate system response.

D8125 POPEX Module

The D8125 POPEX Module is a hardware accessories for the Bosch Security Systems Zone Expansion (ZONEX)
system.
The D8125 POPEX Module is a Point Of Protection EXpander. One or two POPEX Modules can be used to
interface zone expansion loops to the D8112G series. Each POPEX Module can monitor up to 63 POPIT
Modules, and as many as 126 individual POPIT Modules can be monitored in a ZONEX system with two POPEX
Modules. An unlimited number of detection devices can be connected to each POPIT sensor loop; however,
annunciation is available only for the sensor loop.
3.2.1.1 Programming
POPEX/POPIT application programs are developed using the Remote Account Manager or the Bosch Security
Systems D5200 Bar Code Programmer containing the D8112 Handler. The control panel used for the ZONEX
system must be of the D8112"G" Series (referred to in this guide as "D8112G1/G2"). The POPEX/POPIT
Modules will not function with the D8112 "E" or "A" Control/Communicators. The D8112G contains the ZONEX
firmware, and has expanded memory for custom ZONEX text displays on the Bosch Security Systems D1252A
Keypad. (Custom alphanumeric text for each expansion point can be programmed with the D8112 Handler (see
the Omegalarm D8112 Zonex System Program/Account Record Sheet). Each POPEX Module is supplied with a
D8112 ZONEX System Program/Account Record Sheet, used to record both the ZONEX subhandler program file
and the physical location of each POPEX and POPIT Module.
3.2.1.2 Listing
See UL Applications on page 2 to determine the appropriate POPIT module for each application. The POPEX
module can be mounted in any D8103, D8108A or D8109 enclosure.
3.2.2

Operation

Each POPIT Module is assigned to report to a D8112G1/G2 control panel "master zone." The POPIT can
transmit three conditions to the D8112G1/G2: sensor loop open, shorted, and normal. The D8112G1/G2
receives the condition signals and interprets them as sensor loop alarm, trouble, or normal, missing POPIT
module, or extra POPIT module. The D8112G1/G2 "master zone" loop code program determines the system
response to each of these sensor loop conditions. When an event occurs on a POPIT, the D1252A sequences
through displays which indicate the type of event.
