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: new
G Series (B9512G, B9512G-E, B8512G, B8512G-E),
G Series (D9412GV4, D7412GV4, D7212GV4,
D9412GV3, D7412GV3, D7212GV3, 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 (G Series, 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 point status to the control panel.
Also available on the D8125MUX are auxiliary power
terminals labeled Power A (+,-), Power B (+,-) that
support remote devices requiring an uninterrupted
source of power.
The B600 Retrofit (ZONEX) module is
required to use the D8125MUX on the
B9512G, B9512G-E, B8512G, and
B8512G-E control panels.
See the Control Panel Approved Applications Compliance
Guide or the Installation and System Reference Guide to
determine the required equipment and enclosures for
the application.

4.4 Using Power B and MUX BUS B
(Optional)
It might be necessary to use the Power B (+, -) and
MUX BUS B (+, -) terminals for isolation purposes. For
example, an Authority Having Jurisdiction (AHJ) might
require that fire points and burglar points be on
independent buses.
1. Connect Power B+ and Power B- on the
D8125MUX to multiplex devices that require
uninterrupted auxiliary power. Up to 200 mA is
available at these terminals.
2. Connect MUX BUS B + and B - on the D8125MUX
to the positive and negative bus wires of the
multiplex points. The maximum allowable current
on MUX BUS B is 75 mA.
4.5 Wiring Multiplex Devices to the
Multiplex Bus
Use one two-wire data expansion loop using MUX BUS
A, or distribute the devices on both MUX BUS A and B.
Table 5 shows the maximum distance per MUX bus
output - each D8125MUX has two multiplex bus
outputs. Table 6 shows the maximum distance
between the control panel and the D8125MUX.
Determine the required wire gauge for each multiplex
bus expansion loop (Table 5). Programming the
individual multiplex points with the D5060 assigns
them to point numbers. Daisy chain and T-tapping
configurations are acceptable. Refer to Figure 9.

4.6.1 Adding Multiplex Devices to the Control
Panel
Off board points for G Series, D9124, D9412, and
D9112 are numbered 9 through 127 and 129 through
247 (G Series, D7412, and D7212 use off board Points
9 through 75 only; G Series use off board Points 9
through 40 only). G Series, D9412, and D9112 reserves
Points 128 and 248 for internal use. The D8125MUX
connected to ZONEX 1 monitors Points 9 through 127,
whereas the D8125MUX connected to ZONEX 2
monitors Points 129 through 247.
The D8125MUX and multiplex points
connected to ZONEX 2 must be
programmed in the D8125MUX with DIP
switches as Points 9 through 127. Refer to
Table 8 on page 12.
4.6.2 Removing Multiplex Devices from the
Control Panel
To remove a multiplex device from the system:
1. Connect the device to the D5060.
2. Enter the address.
3. Enter 0for the point type.
Ensure that the D8125MUX is not powered
before connecting or disconnecting
multiplex devices. Connecting or
disconnecting a multiplex device while the
D8125MUX is powered causes the
multiplex device address setting to
reprogram or scramble.
After any programming or hardware
change, do a functional test of the system
as required by local codes.

4.7 Point Matrix Tables
Only use one D8125MUX per ZONEX output. Refer to Table 9 beginning on page 14 for ZONEX 1. Refer to Table
10 beginning on page 17 for ZONEX 2
If configuring the system with DS7457i, DS7461i, or DS7465i MUX devices. Refer to Table 11 on page 19 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. G Series, and D7212 Control
Panels use the sheet marked Bank 1.
