Notices
These instructions cover the installation of the D7044
Multiplex Single 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 D7044 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 the procedures
can result in the D7044 not operating
properly. Bosch is not responsible for
improperly installed, tested, or maintained
devices.

Status LED
Zone input terminals
Mux bus loop terminals
Rotary address switches
All operating power for the D7044 is drawn from the
FACP.
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 normal
operation.
Slow: Approximately 16 sec indicating a trouble
condition.
The D7044 can be mounted in a standard double-gang
or a 4 in. x 4 in. electrical box.

Connections are made using the terminals on either side
of the D7044 (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 as
specified by NFPA-70 and the local AHJ.
All wiring is power limited and supervised. Refer to
Figures 3 and 4 for the two types of wiring connections.
Use normally-open (NO) contacts for
