D7042/D7042B Multiplex Eight Input Remote Modules

Installation Instructions

1.0 Introduction

These instructions cover the installation of the D7042/D7042B Eight Input Remote Modules in a fire system supervised
by an FPD-7024 Fire Alarm Control Panel (FACP).
Install, test and maintain the D7042/D7042B Eight Input Remote Modules according to their instructions, NFPA 72,
Local Codes and the Authority Having Jurisdiction. Failure to follow these instructions may result in failure of the
device to operate properly. Bosch is not responsible for improperly installed, tested or maintained devices.

These instructions contain procedures to follow in order to avoid personal injury and damage to equipment.

2.0 Device Description

The D7042/D7042B is an Eight Input Remote Module that provides a means of addressing up to eight input loops of
conventional contacts to the multiplex bus of the control panel. It is suitable for use with the FPD-7024 Fire Alarm
Control Panel (FACP) with ROM version 2.0 or greater using a D7039 Multiplex Expansion Module. Up to 30 D7042/
D7042B modules can be supported per FACP. One D7039 Multiplex Expansion Module is required in the system to
use the D7042/D7042B Eight Input Remote Modules.

3.0 Installing the D7042/D7042B

3.1 Mounting the D7042

Use the mounting holes (upper left and lower right corners) to mount the D7042. The D7042 normally is mounted
outside of the FACP enclosure.

3.2 Mounting the D7042B

The D7042B will come partially preassembled with the circuit board attached to the mounting skirt.
Select a mounting location for the D7042B.

Using the enclosure as a template, mark the mounting holes on the mounting surface and make an opening for the
unit’s wiring.

Next, attach the mounting skirt if applicable (with the circuit board attached) to the enclosure (hardware provided).
Then complete all wiring (see Section 4.0). Once installation and wiring is completed, attach the enclosure cover and
secure with the screws (provided).

Figure 2: Mounting the D7042B

Be sure all wiring is unpowered before routing. Do not use shielded or twisted pair cable.

Refer to the D7039 Installation Guide (P/N: 38685) for multiplex wiring requirements. The length of the wire connected
to the loop inputs on the D7042/D7042B must be less than 250 ft. (76 m) per loop. Route wiring as necessary from the
D7039 in the FACP enclosure and from remote devices to the D7042/D7042B. If the wiring is to run along the surface
of the enclosure, open the D7042/D7042B surface wire entrance. See Figure 2.

Since NFPA 72 does not allow
redundant/duplicate ground paths,
do not connect wiring to the BUS (-)
terminal on this module for fire
applications. Only the BUS (+) needs
to be connected.

When used with a D7039, power is
connected to the option bus power
terminals (RA or RB (+), BA or BB (-)).
Connection t o 24 VDC sources will
damage the D7042/D7042B.

5.0 Programming the D7042/D7042B

Refer to the programming section of the D7024 Reference Guide (P/N: 31499) for point programming information.

The D7042/D7042B occupies eight multiplex point addresses when connected to the control panel.

6.0 Setting the Jumpers and DIP Switches

6.1 D7042 Jumper Settings

P2 of the D7042/D7042B allows the tamper switch to be bypassed with a jumper when testing or servicing.

Remove the jumper on P2 when testing or servicing has been completed.

6.2 D7042/D7042B DIP Switch Settings

The DIP switches select which points will be activated by the loop inputs.
Set the DIP switches as shown in Table 1.

No two D7042/D7042B DIP Switch settings should be the same.

The D7042/D7042B occupies eight points when connected to the FACP.
The input loops of the D7042/D7042B correspond to the points of the
FACP as shown in Table 2. Figure 6 shows the DIP switch positions for
on and off settings.
