Bosch Security Systems, Inc. | 9/08 | F01U034973-02 3
1.0 Introduction
1.1 Description
Use the D8125MUX Multiplex Bus Interface Module
to connect multiplex points to the zonex bus on the
following Bosch Security Systems control panels:
D9412GV2, D7412GV2, D7212GV2, D9412G,
D7412G, D7212G, D9412, D7412, D7212, D9112,
and D9124 with version 5.22 or greater firmware.
Install the D8125MUX on Zonex 1 and Zonex 2
(D9412GV2, D9412G, D9412, and D9112 only). The
multiplex bus interface supports two independent
multiplex buses; therefore, a fault on one multiplex
bus does not prevent the other from operating
normally.
The D8125MUX scans the multiplex points connected
to it and reports the points’ status to the control panel.
Point index programming then determines if the
control panel initiates an action (for example, alarm
response, trouble response, and so on).
Also available on the D8125MUX are auxiliary power
terminals labeled Power A (+,-), Power B (+,-) that
support remote devices requiring an uninterrupted
source of power.
D8125MUX is a Class B (Style 4) signaling line
circuit.
For additional D8125MUX installation information,
refer to the D9412GV2/D7412GV2 Approved
Applications Compliance Guide (P/N: F01U003639).
1.2 Programming
The D8125MUX is programmed using the D5060
Multiplex Point Programmer. The D5060 connects to
the D8125MUX PROG PORT located next to the
POWER A+ terminal. Individual point addresses and
point types are then programmed into the D8125MUX
EEPROM. In addition, the programmer must also
program each multiplex point that is connected to the
system, unless the point is equipped with
programming DIP switches. Reset pins are provided
(located above Zonex Bus Out terminal) to clear the
D8125MUX of all programmed points.
Refer to Section 3.2 Programming on page 6for
programming information.
1.3 Listings

page 5).
3. Enter the point’s three-digit address. The address
must be between 1 and 255. Press [#].
The programmer shows tyP.
4. Enter the number corresponding to the point type
you are programming as shown in Table 3 and
press [#]. The programmer alternately shows the
address and the point type.
When you program for a mutiplex smoke
device by entering decimal value 4 or 5
Table 3, an 18-second timer starts
counting. Do not disconnect the mutiplex
smoke device until after the timer counts
down to zero.

3.8 Point Matrix Tables
Only use one D8125MUX per zonex output. Refer to Table 8 beginning on page 12 for Zonex 1. Refer to Table
9beginning on page 14 for Zonex 2
If configuring the system with DS7457i, DS7461i, or DS7465i MUX devices. Refer to Table 10 on page 16 if
configuring the system with the DS7460iMUX device.
The type of multiplex device used determines the quantity of devices you can connect to the D8125MUX. Do
not program two multiplex points to the same point number. After programming all the points, perform a
Service Walk Test. Refer to the control panel’s operation and installation guide for information on the Service
Walk Test. If a multiplex point is not functioning, check for duplicate addresses.
Two sheets of peel-off labels are supplied with the D8125MUX. Each label has two parts. Place the smaller
part (with the point number) on the multiplex point. Throw away the larger part. Use the sheet marked Bank 1
for Points 9 through 127 and the sheet marked Bank 2 for Points 129 through 247. The D7412GV2,
D7212GV2, D7412G, D7212G, D7412, and D7212 Control Panels use the sheet marked Bank 1.

The devices listed in Table 10 reserve a single point
on the MUX bus. Single Input Multiplex points can be
programmed as Points 9 through 127 (Zonex 1) and
129 through 247 (Zonex 2) (238 devices) on the
D9412GV2, D9412G, D9412, and D9112; Points 9
through 75 (67 devices) on the D7412GV2, D7412G,
D7412, and D7212; Points 9 through 40 on the
D7212GV2 and D7212G (32 devices). When
programming the point type for Single Input Multiplex
points using a D5060 Programmer, refer to Table 11
for information on how to configure the point type.
Tamper conditions on multiplex points are treated as
Missing conditions by the control panel.

3.11 DS7460(i) Dual Input Multiplex
Module
The DS7460(i) reserves two points on the MUX bus.
Dual input multiplex points can be programmed as
Points 9 through 127 (Zonex 1) and 129 through 247
(Zonex 2) (59 per zonex, 118 modules) on
D9412GV2, D9412G, D9412, and D9112: Points 9
through 75 (33 modules) on a D7412GV2, D7412G,
D7412, and D7212; Points 9 through 40 on the
D7212GV2 and D7212G (16 modules). When
programming dual points, they occupy first an odd
point number, then an even point number. For
example, DS7460(i) Modules must be programmed to
occupy Points 9 and 10, not 10 and 11.
The MX250 and MX250TH Photoelectric Smoke
Detectors with MXB2W Base or D7050 and D7050TH
Photoelectric Smoke Detectors and D7050-B6 Base
reserve a single point on the multiplex bus. Single
input Multiplex points can be programmed as points 9
through 127 (Zonex 1) and 129 through 247 (Zonex
2) (238 smoke detectors) on a D9412GV2, D9412G,
D9124, D9412, or D9112; points 9 through 75 (67
smoke detectors) on a D7412GV2, D7412G, D7412,
and D7212; and (32 smoke detectors) points 9
through 40 on the D7212GV2 and D7212G. Other
wiring restrictions can reduce the maximum number
of photoelectric smoke detectors on the multiplex bus.
Refer to the MX250 Installation Guide (P/N: 45253)

automatically added.
The DS7460i cannot be used for Point 75
on the D7412GV2, D7412G, D7412, and
D7212 or for Points 127 or 247 on the
D9412GV2, D9412G, D9412, and D9112.
Failure to observe these programming
requirements will result in intermittent
missing conditions.
In addition, both points on the DS7460i must have a
Point Index assigned to it when programming the
control panel. If one of the two points is not required
on the device, simply place the 47 kΩend-of-line
(EOL) resistor on the point input terminals and
program the unused point with the same Point Index.
When programming the point type for the DS7460(i),
using the D5060 Programmer refer to Table 13 for
information on configuring the point type. Tamper
conditions on multiplex points are treated as Missing
conditions by the control panel.

3.12 DS7432 Eight Input Remote Module
This device type reserves eight points on the
multiplex bus. Each D8125MUX supports fifteen
DS7432s on the D9412GV2, D9412G, D9412, and
D9112 Control Panels, up to eight on the D7412GV2,
D7412G, D7412, and D7212 Control Panels, and up
to four on the D7212GV2 and D7212G Control
Panels. The DS7432s occupy groups of eight points;
however, when programming the DS7432 with the
multiplex point programmer, program them as four
sets of dual points. For example, if using a DS7432
on the system for Points 9 through 16, program
Points 9, 11, 13, and 15 as dual points with the even
points being added automatically. Program starting
point locations for the DS7432 on the D9412GV2,
D9412G, D9412, and D9112 Control Panels as
follows: 9, 17, 25, 33, 41, 49, 57, 65, 73, 81, 89, 97,
105, 113, 121. Refer to Table 14.

Points 127/128 and 247/248 cannot be
programmed when using DS7432s
(D9412GV2, D9412G, D9412, or D9112).
Program starting point locations for the DS7432 on
the D7412GV2, D7412G, D7412, D7212 as follows:
9, 17, 25, 33, 41, 49, 57, and 65. Program starting
point locations for the DS7432 on the D7212GV2 and
D7212G as follows: 9, 17, 25, and 33. Failure to
observe this programming requirement will result in
intermittent missing conditions. All eight points on the
DS7432 must also have a Point Index assigned to
them. If any of the eight point inputs are not required
on the device, place the 47 kΩEOL resistor on the
point input terminals. Refer to Table 15 for
information on configuring the point type. Tamper
conditions on multiplex points are treated as Missing
conditions by the control panel. Removing the cover
and activating the tamper results in a missing
condition for all eight points.

3.13 DS7465(i) Input/Output Module
This device type reserves a single point on the MUX
bus and provides a Form C (NO, C, NC) relay output.
The relay output number assigned to this module is
the same as the point number assigned to it. For
example, if this device was programmed as Point 27,
the relay number is also 27.
The relay output on this module is a fully
programmable relay and follows the relay
programming of the control panel.
The maximum number of DS7465i Modules that can
be placed on the control panels is 56 as points 9
through 64 for the D9412GV2, D7412GV2, D9412G,
D7412G, D9412, D7412, D7212, and D9112; and 16
as points 9 through 24 for the D7212GV2 and
D7212G. Place the DS7465(i) on the D8125MUX
connected to Zonex 1.
If only the relay is required for the installation, assign
a Point Index for the programmed point location, and
place a 47 kΩEOL resistor on the point input
terminals. Refer to Table 16 for point type
configuration.

Tamper conditions on multiplex points are treated as
Missing conditions by the control panel. Using
DS7465i Input and Output Modules on the system
does not interfere with the use of D8129 OctoRelay
Modules.
