Notices
These instructions cover the installation of the D7052
Multiplex Dual Input Module in a fire system
supervised by a D7024 or DS9400M Fire Alarm
Control Panel (FACP) with firmware revision 2.0 or
greater and a D7039 or DS9431 Multiplex Expansion
Module.
Install, test, and maintain the D7052 according to these
instructions, NFPA 72, local codes, and the Authority
Having Jurisdiction (AHJ).
Follow the procedures in these instructions
to avoid personal injury and damage to
equipment. Failure to follow these
instructions can cause the D7052 to not
operate properly. Bosch is not responsible
for improperly installed, tested, or maintained
devices.
Test the FACP according to NFPA 72.
1.0 Description
The D7052 (Figure 1) is a general purpose module that
connects to the multiplex bus of the control panel. It
provides two supervised Class “B” input zones or one
Class “A” input zone. Use a jumper pin setting for a
Class “A” or Class “B” wiring configuration.
All operating power for the D7052 is drawn from the
control panel. Rotary switches provide convenient
address setting.
An on-board Status LED, visible through the faceplate,
indicates normal operation and communication with the
control panel. The LED flash rates are:
• Fast: Approximately 4 sec indicating an alarm
condition.
• Medium: Approximately 8 sec indicating a normal
operation.
• Slow: Approximately 16 sec indicating a trouble
condition.
The D7052 can be mounted in a standard double-gang
or a 4 in. x 4 in. electrical box.

2.0 Setting the Address
Set the D7052 address using a flat-blade screwdriver to
position each rotary switch located on the front of the
module (Figure 2). Note that the switches click when
turned.

The valid address range is 9 to 255. Refer to the D7024
Operation and Installation Guide (P/N: 31499) or the
DS9400M Reference Guide (P/N: 44578) for additional
address limitations.
The D7052 requires two program addresses. The address
cannot be 8 or a multiple of 8, such as 16, 24, 32, and so
on.

D7052 | Installation Instructions | 3.0 Wiring
The A address range works on the D7039
Multiplex Expansion Module with the D7024
FACP. The B address range works on the
DS9431 Multiplex Expansion Module with
the DS9400M FACP.
Figure 2 on page 2 shows the input address set at 095.
The second input address will be set to the next
consecutive address, 096. Because the hundreds address
is within the input address range, it works on the D7039
with the D7024 FACP.
3.0 Wiring
Remove all power before making electrical
connections. Failure to do so can result in
personal injury and damage to the
equipment.
Use normally-open (NO) contacts for
Underwriters Laboratories, Inc. (UL) Listed
fire installations.
The wiring connections are made using the terminals on
either side of the D7052 (refer to Figure 1 on page 2). All
terminals can accommodate up to and including
12 AWG (2.3 mm) wire. Follow the wiring guidelines as
specified by NFPA-70 and the local AHJ.
All wiring is power limited and supervised. Refer to
Figure 3 and Figure 4 for the two types of wiring
connections.
Ensure the D7052 is correctly configured for Class “A”
or Class “B.” Refer to Figure 5 for jumper settings.
