D7044M | Installation Instructions |
Notices
These instructions cover the installation of the D7044M
Multiplex Mini 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 D7044M 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
procedures can cause the D7044M 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 D7044M (Figure 1) is a general purpose module that
connects a contact device to the FACP’s multiplex bus
with a supervised input loop. All operating power for
the D7044M is drawn from the FACP.
Rotary switches (Item 3 in Figure 1) 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 D7044M can be inserted in a standard single-gang
electrical box.
2.0 Setting the Address
Set the D7044M address using a single point screwdriver
to position each rotary switch located on the front
(Figure 2). Note that the switches click when turned.
The valid D7044M 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 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 shows the A address range set at 095, allowing
the D7039 to work with the D7024 FACP.
