Notices
Use these instructions to install the D7039 Multiplex
Expansion Module in a fire system supervised by a
D7024 Fire Alarm Control Panel (FACP).
Install, test, and maintain the D7039 according to these
instructions, NFPA 72, local codes, and the Authority
Having Jurisdiction (AHJ).
Follow the procedures in this document to
avoid personal injury and damage to the
equipment. Failure to follow these
procedures can cause the D7039 to not
operate properly. Bosch is not responsible
for improperly installed, tested, or maintained
devices.
For the D7039 with ROM version 1.04 to
operate properly, the D7024 FACP must be
running version 2.05 or later firmware.
1.0 Description
The D7039 (Figure 1) connects directly to the FACP for
either two Class B multiplex buses or one Class A
multiplex bus that allows up to 247 remote points.
When configured for Class A operation,
the D7039 can only support Addresses 9
through 128.

2.0 Installation
Failure to follow the mounting instructions in this document can damage the FACP.
The D7039 and D7024 have static sensitive components and must be handled with care. Follow the
anti-static procedures when handling these modules.
Before installing the D7039 Module, remove all AC and battery power to the FACP.
1. If the D7024 is already installed in an enclosure, remove it.
2. Place the FACP on a flat surface with the component side facing up (Item 2 in Figure 2).
3. Insert the four plastic standoffs in the mounting holes (Item 3 in Figure 2) without bending or flexing the FACP.
4. Align the standoff tabs so they do not touch the module components.
5. Firmly press the standoffs into the board, allowing the ears to expand out.
6. Mount the D7039 on the standoffs, ensuring the FACP connector pins (Item 4 in Figure 2) are properly aligned.
7. Install the FACP in the enclosure.
8. Use the mounting screw (Item 5 in Figure 2) to secure the D7039’s ground wire (Item 6 in Figure 2) to the FACP.

9. Mount the D7039 I/O Module (Item 1 in Figure 3) in the FACP enclosure (Item 2 in Figure 3) using the mounting
holes in the enclosure (Item 3 in Figure 3).
10. Connect the yellow and green earth ground wire from the I/O module to the earth ground terminal on the
FACP control board (Item 4 in Figure 3).
3.0 Wiring
1. Connect the D7039 multiplex loop using up to 3800 ft (1170 m) of 18 AWG (1.0 mm2) or 5950 ft (1810 m) of
16 AWG (1.5 mm2) wire (Figure 4). Do not use shielded wire.
Do not use shielded wire. Twisted pair is acceptable, but is not recommended.

You can configure the D7039 with a single fault tolerant Class “A” loop or as a pair of supervised Class “B”
loops. When configured as a Class “A” loop and installed on a D7024 Control Panel before Lot #100, the
D7039 implements a Style 4.5 signaling line circuit (SLC). When installed on a D7024 Control Panel Lot #100
or later, the D7039 implements Style 6 SLC. Refer to the D7024 Operation and Installation Guide (P/N: 31499)
for programming.
When configured as a Class “B” loop and installed on a D7024 Control Panel before Lot #100, the D7039
implements a Style 3.5 SLC. When installed on a D7024 Control Panel Lot #100 or later, the D7039
implements a Style 4 SLC. Refer to the D7024 Operation and Installation Guide (P/N: 31499) for programming.
2. Measure loop resistance by shorting the end of the farthest device in Class “B” (Figure 5) or shorting the return
wire in Class “A” (Figure 6) and reading the total resistance of all wires associated with the loop.
3. Ensure the loop is disconnected from the D7039 Module.
