D7035/D7035B Octal Relay Module

Installation Guide

1.0 Notice

These instructions cover the installation of the Radionics D7035/D7035B Octal Relay Modules in a fire system

supervised by a Radionics D7024 Fire Alarm Panel (FACP).

Install, test and maintain the D7035/D7035B 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.

2.0 Device Description

The D7035/D7035B is an Octal Relay Module that provides eight Form “C” relay outputs for addition to the D7024

Control. It connects to the D7024 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.

3.0 Installation

Before installing the D7035/D7035B, disconnect all power (AC and battery) from the control panel.

3.1 Installing the D7035 inside the FACP Enclosure

Use the following steps when installing the D7035 inside the FACP enclosure:

1) 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.

See Figure 2 and/or Figure 3. 5) Refer to section 4.0 for wiring instructions. Wiring the D7035/D7035B The D7035/D7035B is wired to the control panel’s option bus.
PAGE 4
All option bus devices must be connected to the same bus (either Bus A or Bus B). Do not connect some devices to Bus A data terminals (YA, GA) and some to Bus B (YB, GB). Power (RA and RB terminals) and ground (BA and BB) may be connected interchangeably to either set of terminals. There are three terminals for each of the eight relays: Normally Open (NO), Common (C) and Normally Closed (NC). To wire the contacts, see Figure 5. Figure 5: Wiring the D7035/D7035B Contacts 5.
