Overview
2.2 D9412G/D7412G Point Expansion
The D9412G can use Point of Protection Input Transponder (POPIT) Modules to provide a maximum of 238 off-board
points, bringing the total number of points the D9412G can monitor to 246. The D7412G provides up to 67 off-board
points, bringing the total number of points the D7412G monitors to 75. Each
off-board point requires a POPIT Module.
POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data
expansion loops connect to a D8125 Point of Protection Expander (POPEX) Module. POPEX Modules connect to the point
bus on the panel, Terminals 23 and 24 for power (3 and 9 on the D7412G), and Terminals 25 and 26 (D9412G only), or 27
and 28 for data.
If a programmed POPIT is disconnected from the expansion loop, a missing condition appears immediately and the event is
logged. The missing condition may also be transmitted to a central station or printed to an on-site printer, if programmed to
do so. See the D9412G/D7412G Program Entry Guide for programming options.
Extra Point events are generated when a POPIT is connected to the data expansion bus but does not have a Point Index
assigned to it. Shown below are instances when an Extra Point event is or is not generated.
If a POPIT is connected to the data expansion bus but does not have a Point Index assigned to it and…
· the data expansion bus becomes disconnected, no trouble condition is annunciated or displayed at command centers
and the Extra Point event is not generated. (However, POPITs programmed with a Point Index immediately go
missing.)
· the data expansion bus restores to a normal condition from an open, a trouble condition annunciates and displays at
the command center. In addition, an Extra Point event is generated, logged, and may be programmed to be sent to the
central station or printed to an on-site printer.
· the point input goes from an electrically normal state to an open or shorted state, the command center neither
annunciates nor displays a trouble condition. No Extra Point event is generated.
· the system is presently in a Service Walk Test and the point input goes from an electrically normal state to an open or
shorted state, the command center neither annunciates nor displays a trouble condition. However, an Extra Point
event is logged and printed to an on-site printer, if programmed. Note: The Service Walk Test never displays a points’
electrical state as‘Extra’.
If the positive or negative leg of the data expansion bus is shorted to earth ground and Ground Fault Detect is enabled, a
general Ground Fault event is generated.
If the positive or negative leg of the data expansion bus becomes disconnected, all POPITs beyond the break report as a
missing condition.
If the data expansion bus becomes shorted, all POPITs report a missing condition and a Pt Bus Trouble event is generated.
When the data expansion bus restores from a shorted condition, a Pt Bus Restore event is generated, and if there are POPITs
connected to the data expansion bus without a Point Index assigned to it, an Extra Point event is generated.
If the positive or negative leg of the data expansion bus becomes shorted to a Common terminal on the D7212G, all POPITs
report a missing condition. In addition, a Pt Bus Trouble event is also generated.
If Terminal 28 becomes shorted to a Common terminal, a Pt Bus Trouble event is not generated. However, a short between
Terminal 27 and a Common terminal generates a Pt Bus Trouble event and the command center displays SERVC ZONEX
1. If Terminal 27 and Terminal 28 are shorted together, a Pt Bus Trouble event is generated and the command center displays
SERVC ZONEX 1.
The D7212G responds to missing point conditions based on how the points are programmed and which armed state the
area is in the point is assigned to. For example, if an interior motion detector point went missing during a disarmed state, a
Missing Trouble event is generated. However, if the point went missing while the area was Master Armed, a Missing Alarm
event is generated. Non-fire, 24-hour points always generate a Missing Alarm event whereas Fire points always generate a
Missing FireTrouble event.

Overview
2.2.1 D8125 POPEX/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.
2.2.1.1 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 Electrically Actuated Transmitter Applications.
See the D9412G/D7412G Approved Applications Compliance Guide to determine the required equipment and enclosures for
the application.
2.3 D7212G Point Expansion
The D7212G can use POPIT (Point of Protection Input Transponder) Modules to provide up to 32 off-board points,
bringing the total number of points the D7212G can monitor to 40.
POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data
expansion loops connect to a D8125 POPEX (Point of Protection Expander) Module.POPEX Modules connect to the point
bus on the panel, Terminals 3 and 9 for powerand Terminals 27 and 28 for data.
If a programmed POPIT is disconnected from the expansion loop, a missing condition appears immediately and the event is
logged. The missing condition may also be transmitted to a central station or printed to an on-site printer, if programmed to
do so. See the D7212G Program Entry Guide (P/N: 4998138538) for programming options.
Extra Point events are generated when a POPIT is connected to the data expansion bus but does not have a Point Index
assigned to it. Shown below are instances when an EXTRA POINT event will or will not be generated.
If a POPIT is connected to the data expansion bus but does not have a Point Index assigned to it and…
· the data expansion bus becomes disconnected, no trouble condition is annunciated or displayed at command
centers and the EXTRA POINT event will not be generated. (However, POPIT’s that are programmed with a
Point Index will immediately go missing.)
· the data expansion bus restores to a normal condition from an open, a trouble condition will annunciate and
display at the command center. In addition, an EXTRA POINT event is generated, logged, and may be
programmed to be sent to the central station or printed to an on-site printer.
· the point input goes from an electrically normal state to an open or shorted state, the command center will
neither annunciate nor display a trouble condition. No EXTRA POINT event will be generated.
· the system is presently in a Service Walk Test and the point input goes from an electrically normal state to an open
or shorted state, the command center will neither annunciate nor display a trouble condition.However, an
EXTRA POINT event will be logged and printed to an on-site printer, if programmed. Note: The Service Walk
Test will never display a points’electrical state as‘Extra’.
If the positive or negative leg of the data expansion bus is shorted to earth ground and Ground Fault Detect is enabled, a
general GROUND FAULT event is generated.
If the positive or negative leg of the data expansion bus becomes disconnected then all POPIT’s beyond the break will report
as a missing condition.
If the data expansion bus becomes shorted then all POPIT’s will report a missing condition and a PT BUS TROUBLE event is
generated. When the data expansion bus restores from a shorted condition, a PT BUS RESTORE event is generated and if
there are POPIT’s connected to the data expansion bus without a Point Index assigned to it, then an EXTRA POINT event
will be generated.

Overview
If the positive or negative leg of the data expansion bus becomes shorted to a Common terminal on the D7212G then all
POPIT’s will report a missing condition. In addition to this, a PT BUS TROUBLE event will also be generated.
If Terminal 28 becomes shorted to a Common terminal, a PT BUS TROUBLE event will not be generated. However, a short
between Terminal 27 and a Common terminal will generate a PT BUS TROUBLE event and the command center will display
SERVC ZONEX 1. If Terminal 27 and Terminal 28 are shorted together, a PT BUS TROUBLE event is generated and the
command center will display SERVC ZONEX 1.
The D7212G will respond to missing point conditions based on how the points are programmed and which armed state the
area is in that the point is assigned to. For example, if an interior motion detector point went missing during a disarmed
state, a MISSING TROUBLE event would be generated. However, if the point went missing while the area was Master
Armed, a MISSING ALARM event would be generated. Non-fire 24-hour points always generate a MISSING ALARM event
whereas Fire points always generate a MISSING FIRE trouble event.
2.3.1 D8125, D8127 and D9127 POPIT Modules
D8127 and D9127 POPITs use the D8125 POPEX Module to report to the panel.The D8125 supports up to 32 POPIT points
(Points 9 to 20).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 come with untampered
covers. Unless the module is mounted in a tampered enclosure, UL requires D8127T and D9127T Modules for certificated
accounts.
2.3.1.1 Listings
The D8125 POPEX and the D8127 and D9127 POPIT Modules are UL Listed for use with the D7212G for Central Station,
Local, Police Connect, Bank Safe and Vault, Mercantile Safe and Vault, and Grade A Household systems, and Proprietaryas
a Control Unit for Household Fire Warning. The D7212G is not listed for commercial fire applications.
See the D7212G Approved Applications Compliance Guide (P/N: 4998138560) to determine the required equipment and
enclosures for the application.
2.4 Non-G 9000 Series Point Expansion
On the D9412/D9112, you can use POPIT (Point Of Protection Input Transponder) modules to provide up to 238 off-board
points, bringing the total number of points the D9412/D9112 can monitor to 246. The D7412/D7212 can provide up to 67
off-board points bringing the total number of points the D7412/D7212 can monitor to 75. Each off-board point requires a
POPIT module.
POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data
expansion loops connect to a D8125 POPEX (Point Of Protection EXpander) module.POPEX module(s) connect to the
point buss on the panel, Terminals 23 and 24 for power (3 and 9 on the D7412 and D7212), and terminals 25 and 26 (D9412/
D9112 only), or 27 and 28 for data.
If a POPIT is disconnected from the expansion loop, a trouble message appears immediately. See the D9412G/D7412G
Program Entry Guide (P/N: 47775) for programming options.
If you connect a POPIT to the expansion loop that is programmed for a point number that does not appear in the program
for the D9412/D9112, it appears as a trouble condition when the data expansion loop restores from a faulted condition. A
faulted condition on the data expansion loop includes:
1. Positive leg of the data expansion loop shorted to ground.
2. Negative leg of the data expansion loop shorted to ground.
3. Data expansion loop (positive or negative leg) becomes disconnected.
4. Data expansion loop becomes shorted.
Placing a short on the data expansion loop generates a PT BUS TROUBLE report. The panel sees all points on the shorted
expansion loop as shorted, and responds according to point programming, except for fire points. The fire points will
respond locally as a trouble condition and transmit missing fire reports if programmed during this condition.
POPIT modules monitor their sensor loops for three conditions, loop normal, loop open, and loop shorted. They report
these three conditions to the D9412/D9112.

Overview
The D9412/D9112 uses point programming to interpret the sensor loop information reported by the POPITs and make the
appropriate system response.
2.4.1 D8125 POPEX/ D8127 and D9127 POPIT Modules
D8127 and D9127 POPITs use the D8125 POPEX module to report to the D9412/D9112.Each D8125 supports up to 119
POPIT points. Connect two D8125 modules to the D9412/D9112 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 D9412/D9112 reserves Points 128 and 248 for internal use. The D9412/D9112 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 come with untampered
covers.Unless the module is mounted in a tampered enclosure,UL requires D8127T and D9127T modules for certified
accounts.

the application.
2.5 D9112B1/D7212B1 Point Expansion
The black-on-white and white-on-black circled numbers correspond to the terminal labels on the faceplate of any of the 9000
Series panels.
You can use POPIT modules to provide up to 126 off-board points, bringing the total number of points the D9112B1 can
monitor to 134, The D7212B1 can monitor up to 40 off-board points for a total of 48 points.
Each off-board point requires a POPIT module.
POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data
expansion loops connect to a D8125 POPEX module. POPEX modules connect to the point buss on the panel,Terminals 23
and 24 for power (Terminals 3 and 9 for D7212B1) and Terminals 25 and 26 (D9112B1 only), or 27 and 28 for data.
If a POPIT is disconnected from the expansion loop, a trouble message appears immediately.
If you connect a POPIT that is programmed for a point number that does not appear in the program for the D9112B1/
D7212B1 to the expansion loop, it appears as an extra point at the command centers when the point is faulted, and during
the service walk test.
Placing a short on the data expansion loop generates a PT BUS TROUBLE report. The panel sees all points on the shorted
expansion loop as shorted, and responds according to point programming.
POPIT modules monitor their sensor loops for three conditions; loop normal, loop open, and loop shorted. They report
these three conditions to the control panel. A ground on a POPIT sensor loop reports as an open.
The D9112B1/D7212B1 uses point programming to interpret the sensor loop information reported by the POPITs and make
the appropriate system response.
2.5.2 D8125 POPEX Module/D8127 and D9127 POPIT Modules
D8127/D9127 POPITs use the D8125 POPEX Module to report to the D9112B1. Each D8125 supports up to 63 POPIT points
(40 for the D7212B1). Connect two D8125 Modules to the D9112B1 (one for D7212B1) to bring the combined total number
of POPIT and on-board points to 134 for the D9112B1.Points 9 to 71 connect to the first POPEX module. The D9112B1
reserves Points 72 and 136 for internal use. Points 73 to 136 connect to the second POPEX module.The D9112B1 only
annunciates activity for each POPIT, not each detection device connected to the sensor loop.For the D7212B1,Point 9 to 48
connect to the POPEX module.

The D8125 POPEX and D8126/D8127 POPIT Modules are 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 D8126/D8127 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.
The D8127 is a smaller version of the D8126. There are two different versions of the D8126/D8127 POPIT Modules; the
D8126T/D8127T plastic enclosure, which contains a tamper switch, and the D8126U/D8127U,which comes in an untampered
enclosure. Both enclosures are made of UL Listed fire retardant material.
2.6.1.1 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 Command Center. (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 an 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.

See UL Applications in Section 2.1 Specifications to determine the appropriate POPIT module for each application. The
POPEX module can be mounted in any D8103, D8108A or D8109 enclosure.
2.6.2 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 (see D8112 Handler) 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.

3.1.3 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. Refer to Section 3.1.6 POPIT Module Point Assignments.
Determine the required wire gauge for each data expansion loop using Table 4.
3.1.3.1 Combine data expansion loops
The maximum lengths shown in Table 4 are for all data expansion loops
connected to the same POPEX module combined.
Before installing the POPITs, make sure the resistance on the data expansion
loop is no more than 40 Ω.
3.1.3.2 Wiring POPITs together
Do NOT connect POPITs to each other in series, or with a T-tap. Doing so may cause random missing POPIT
conditions.Follow the procedure below to connect POPITs to one another in parallel. Figure 3 shows a typical
configuration.
1. Connect the positive (+) Data terminal from one POPIT to the positive (+) Data terminal on the next POPIT.
2. Connect the negative (-) Data terminal from one POPIT to the negative (-) Data terminal on the next POPIT.
3. Repeat steps 1 and 2 to connect all POPITs to the expansion loop.You don’t need to wire the POPITs in any
particular order on the loop. The switch setting on each POPIT assigns it a point number, regardless of its
physical location.
Three inch clearance for tampered POPITs: Mount tampered POPIT Modules at least 3.0 in. (76 mm) apart to prevent the
tamper magnets from interfering with each other.
3.1.4 Wiring Data Expansion Loops to POPEX Modules
There are two positive (+) and two negative (-) data expansion loop terminals on each POPEX module. Follow the
procedure below to connect the data expansion loops to the D8125 POPEX Module (refer to Figure 3). Remember you can
only connect a maximum of 119 POPITs to one D8125 on the D9412/D9112 and 67 for the D7412/D7212.
1. Connect the positive (+) Data terminal from the first POPIT on the data expansion loop to one of the D8125
module’s positive (+) terminals.
2. Connect the negative (-) Data terminal from the first POPIT on the data expansion loop to one of the D8125
module’s negative (-) terminals.
3.1.5 POPIT Sensor Loops
The number of normally-open and/or normally-closed detection devices each sensor loop can supervise is limited only by
the resistance on the loop.Resistance on each sensor loop must be less than 100 Ωnot including the End-of-Line Resistor.
Certain UL and NFPA applications may limit the number of detection devices. Consult the appropriate UL or NFPA
standards.
Terminate each POPIT sensor loop with the 33 kΩEnd-Of-Line resistor (D106F) included with each POPIT.
Bosch Security Systems recommends you use twisted-pair wire (six twists per foot) in all POPEX/POPIT installations for
both the data expansion loop wiring and the POPIT sensor loops. Run wires away from AC sources to prevent AC
induction. If you suspect a noisy environment, use shielded cable.

3.1.6 POPIT Module Point Assignments
Six switches on each D8127 POPIT assign the module to a point number. D9127 ASIC POPITs have seven switches (0-6) that
assign the module to a point number. POPIT switch settings are found in the Point Assignment section of the D9412G/
D7412G Program Record Sheet (P/N: 47488). See Figure 6 .
For the D9412/D9112,point numbers 73 to 127 and 193 to 247 must use D9127 POPITs. Points 9 to 72 and 129 to
192 may use either D8127 or D9127 POPITs. For the D7412/D7212, Points 9 to 72 may use either D8127 or D9127
POPITs; however, D9127 POPITs must be used for
Points 73-75.
3.1.6.1 Program Record Sheet
The first column on the program record sheet contains the switch
settings for the POPITs. Switches are numbered 1 to 6, left to right
on the D8127 POPIT. Switches are numbered 0 to 6, left to right on
the D9127 POPIT. Set switches whose number appears in the
setting to the ON position. Set switches with a dash (-) in the
switch position to the OFF position (see Figure 4).
The second column contains the translation of the point number
into the ZONEX format. See Point User Flag in the Panel Wide
Parameters module of the D9412G/D7412G Program Entry Guide
(P/N: 47775) for an explanation of this feature.
The third column contains the point number as it is displayed at command centers.
The fourth column contains the point index.See the Point Index Parameters module in the D9412G/D7412G Program Entry
Guide (P/N: 47775) for an explanation of the point index.
The fifth column of the Program Record Sheet shows the area the point is assigned to. The sixth column shows the Debounce
Count for the point. See Debounce Count in the Point Assignments module in the D9412G/D7412G Program Entry Guide (P/
N: 47775).
The seventh column shows the BFSK report code. It is the point number reported for this point when the panel is using the
BFSK format. The eighth column contains the text displayed at command centers for the point. The text is transmitted to the
receiver when the panel is using the Modem IIIa2 format.
3.1.6.2 POPIT Labels
Off-board points for the D9412 and D9112 are numbered 9 to 127 and 129 to 247 (D7412 and D7212 use Points 9 through 75
only). The D9412/D9112 reserves Points 128 and 248 for internal use.You must connect POPITs for Points 129 through 247
to expansion loops connected to POPEX #2.
Two sheets of peel-off POPIT labels are supplied with the D8125 POPEX module.Use the sheet marked Bank1 for Points 9 to
127. Use the sheet marked Bank2 for Points 129 to 247.
Each label has two parts. Place the smaller part, with just the point number on it, on the chip. Place the larger part with the
switch settings on the base of the POPIT. Set the switches and cover the POPIT.
Do not program two POPITs for the same point number. After you program all the points, perform a service walk test. The
Troubleshooting section of this document contains instructions for performing a service walk test. If a point does not test,
check the programming for a duplicate address switch settings.
