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.

Description

The D7044 (Figure 1) is a general purpose device that

connects a contact device to the FACP multiplex bus

with a supervised input loop.

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.

Setting the Address

Figure 3: Field Wiring Connections

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.

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.

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
