D7048(B)	Octal Driver Module

Installation Guide

1.0Notice

These instructions cover the installation of the Radionics D7048(B) Octal Driver Modules in a fire system supervised by a Radionics D7024 Fire Alarm Panel (FACP).

Install, test and maintain the D7048(B) 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. Radionics 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.

Test the D7048(B) in accordance with NFPA 72.

2.0Device Description

The D7048(B) is a Solid State Octal Driver Module that provides eight open collector transistor outputs for addition to the D7024 Fire Alarm Control/Communicator. It connects to the panel via the Option Bus. The outputs are fully programmable and can be activated by several system events. Each output operates individually of the other seven outputs for complete flexibility.

3.0Installation

The D7048(B) is static-sensitive. Use proper static controls when handling the D7048(B).

Before installing the D7048(B), disconnect all power (AC and battery) from the system. Failure to do so may result in personal injury and/or damage to the equipment.

3.1Installing the D7048 inside the FACP Enclosure

Use the following steps when installing the D7048 inside the FACP enclosure:

1)Disconnect all power from the FACP by turning off the AC supply circuit and disconnecting the red battery lead.

2)Remove the two optional transformer studs from the enclosure using either pliers or a hammer to rock them loose. Push the studs back through the enclosure. If the enclosure is already mounted, pull the studs forward through the back of the enclosure instead of pushing them back. See Figure 1 for details.

3)Place the mounting clips in the enclosure as shown in Figure 1.

4)Insert the upper length of the D7048 board underneath the lips of the mounting clips holding the control panel board in place. See Figure 1.

5)Fasten screws through the lower mounting holes on the D7048 and mounting clips from step 3. See Figure 1.

6)Refer to section 4.0 for wiring instructions.

3.2Installing the D7048B Outside the FACP Enclosure

The preferred mounting for the D7048 is directly inside the FACP enclosure, using the provided mounting site. The D7048B kit (which contains a D7048 Octal Driver Module, one MP-D203 Mounting Skirt, and one AE203R Fire Enclosure) may, however, be mounted in its own enclosure near the FACP using the following procedure.

The D7048B may be mounted up to 250 feet (76 m) from the D7024 panel using #18 AWG (1.2 mm) wire. No more than 4,000 ft. (1,219 m) of wire may be attached to the FACP option bus terminals. Refer to the FACP’s installation manual for additional option bus wiring information. The length of wiring connected to the outputs on the D7048(B) must be less than 20 ft. (6.1 m).

1)Choose an appropriate location for the AE203R enclosure.

2)Using the enclosure as a template, mark the mounting holes on the mounting surface and make openings for the unit’s wiring. It is recommended that the option bus wiring enter the AE203R enclosure from the left and the D7048 output wiring exit the enclosure to the right. See Figure 2.
