Setting the Address
Set the D7044 address using a flat-bladed screwdriver to
position each rotary switch located on the front of the
module (Figure 2). Note that the switches click when
turned.

A = D7024 FACP, B = DS9400M FACP
For example:
0 hundreds, 9 tens, 5 ones = Address 095 on the
The valid D7044 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.

Wiring
Ensure all power is removed before making
electrical connections. Failure to do so can
result in personal injury and damage to the
equipment.
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
Underwriters Laboratories, Inc. (UL) Listed
fire installations.
