Notices
These instructions cover the installation of the D7053
Multiplex Input/Output 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 of DS9431 Multiplex Expansion
Module.
Install, test, and maintain the D7053 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 the
equipment. Failure to follow these
instructions can result in the D7053 not
operating properly. Bosch is not responsible
for improperly installed, tested, or maintained
devices.
Test the FACP according to NFPA 72.
1.0 Description
The D7053 (Figure 1) is a general purpose module that
connects to the control panel’s multiplex bus and
provides a supervised input loop and a Form “C” Relay
output.
All operating power for the D7053 is drawn from the
control panel.
Rotary switches provide convenient address setting.
An on-board Status LED, visible through the low-profile
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 D7053 can be mounted in a standard double gang
box or a 4 in. x 4 in. electrical box.

2.0 Setting the Address
Set the D7053 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.

D7053 | Installation Instructions | 3.0 Wiring
The D7053 requires two program addresses. The address
cannot be 8 or any multiple of 8 such as 16, 24, 32, and
so on.
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 output address is 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 or damage to the equipment.
The wiring connections are made using the zone wiring
and MUX bus loop terminals located on either side of
the D7053 (Items 2 and 3 in Figure 1 on page 2).
All terminals can accommodate up to and including
12 AWG (2.3 mm) wire. Follow the wiring guidelines
specified by NFPA 70 and the local AHJ.
The loop and zone wiring is power limited and
supervised. The relay contacts are not power limited or
supervised. Refer to Figures 3 and 4 for wiring
connections.
