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.

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 0 for 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.

4.8 Single Input Multiplex Devices
The devices listed in Table 12 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 G Series,
D9412, and D9112; Points 9 through 75 (67 devices)
on G Series, D7412, and D7212; Points 9 through 40
on G Series (32 devices). When programming the point
type for Single Input Multiplex points using a D5060
Programmer, refer to Table 12 for information on how
to configure the point type. Tamper conditions on

5.0 Testing the System
5.1 Local Walk Test (Command 44)
While disarmed, check the security system’s status by
entering [COMMAND] [4] [4] at the D1255 or D1260
Keypad. This command initiates a System Walk Test.
Each point of protection is scanned by the control
panel, and points are displayed on the D1255 as they
are activated. An accompanying tone is heard from the
keypad to alert the user of an activated point. When all
the burg points are tested, 0 POINTS TO TEST
appears and the system returns to normal operation.
Points failing to report during the Walk Test can be
viewed by pressing [NEXT] until the display reads
VIEW UNTESTED ? Press [NEXT] to view the faulty
points.
Refer to the Security System Owner’s Manual
(P/N: 71-06633-000) for more details on the Local
Walk Test features.
5.2 Missing Multiplex Points
Multiplex points appearing as missing on the display
are usually not connected properly to the multiplex
bus, not programmed correctly, nor have incorrect DIP
switch settings.
Check the multiplex bus wiring to the missing point
and its programming.
5.4 Ground Fault Notification on
Multiplex Devices
When the Loop Input (+) is in a normal condition, a
ground fault on the Loop Input (+) terminal is initially
signaled as a point trouble. A ground fault condition is
signaled by the system after the normal 30 second
ground fault detect time. To witness the ground fault
indication on the keypad, the point trouble must be
cleared from the display by pressing [Command] [4]
on a D1255 and D1260 or [Trouble Silence] on a
D1256. The control panel History Log, shown on a
keypad or sent to the central station, also indicates the
ground fault detection. An Alarm condition is still
indicated even during the occurrence of a ground fault
condition.
When the loop is in an open position, a ground fault on
the Loop Input (+) terminal disrupts supervision. An
open on the loop does not indicate a new fault,
because the ground fault is interpreted as an open. A
short might indicate an Alarm condition depending on
the control panel’s programming.
5.3 Extra Multiplex Points
Extra Points occur when the D8125MUX sends point
transitions back to the control panel and the control
panel does not have a Point Index programmed for it.
Extra multiplex points are reported to the control
panel as a trouble event at the keypad or central
station. The keypad shows the default custom text for
the point number as programmed in the RADXPNTS
(handler).
When an extra point is activated during the Service
Walk Test, it appears as an extra point in the control
panel’s event log and at the local printer (if installed).
Use VIEW LOG to view the control panel’s event log.
Once an extra point is identified, check the
programming to see if it has a Point Index
programmed. Determine if the point belongs in the
system.
Refer to Section 6.0 Troubleshooting on page 25 for
more information.

Verify the wiring to the multiplex points and the
D8125MUX does not have nicks or cuts in the
insulation that can short to nearby conduit.
Make sure wires are tight under terminals of
multiplex points and on the D8125MUX.
Remove the sensor wiring from the multiplex
point and meter it for continuity.
There should be no more than 100 of
resistance, plus the EOL resistance. If you read
less than the EOL resistance look for shorts in
the wiring.
With the wires for the sensor removed, use a
meter to check them for continuity to ground.
A ground before the EOL resistor on a multiplex
points’ sensor loop is interpreted as a short. If
the multiplex point is programmed for trouble
on short, a ground before the EOL causes the
multiplex point to send a trouble report.
The control panel ignores events generated
while the programming or reset switch is down.
Multiplex points programmed for the same
address do not function correctly. Check the
programming of each multiplex point with the
multiplex point programmer.
