3 | Installation

After you set the address switches for the proper address, install the 

module in the enclosure, and then wire it to the control panel and other 

devices.

NOTICE!

Remove all power (AC and battery) before making any 

connections. Failure to do so might result in personal injury 

and/or equipment damage.

3.1 | Mount the module in the enclosure 

Mount the module into the enclosure’s 3-hole mounting

pattern using the supplied mounting screws and mounting

bracket. Refer to 

Figure 3.1.

3.2 | Mount and wire the tamper switch

For instructions on this optional switch, refer to the 

Conettix Ethernet 

Communication Module (B426) Installation and Operation Guide

 (P/N: 

F01U266226) and the 

EZTS Cover and Wall Tamper Switch Installation 

Guide

 (P/N: F01U003734). 

3.3 | Wire to an SDI or SDI2 control panel

When you wire a B426 to an SDI or SDI2 control panel, you can use 

either the module’s terminal strip labeled R, Y, G, B (PWR, A, B, COM) 

or the module’s interconnect wiring connectors (wire included). 

Figure 1.1

 indicates the location of both the terminal strip and the 

interconnect  connectors on the module. Refer to 

Figure 3.2.

NOTICE!

Use either the terminal strip wiring 

or

 interconnect wiring 

connector to the control panel. Do not use both. When 

connecting multiple modules, you can combine terminal strip 

and interconnect wiring connectors in series.

1 | Overview

NOTICE!

The module must be mounted in either the control panel’s 

enclosure or in a listed enclosure such as the D8103 

Universal Enclosure.

NOTICE!

Before browsing to a new settings page, you must click 

OK 

to save edited values. 

Set the address switches per the control panel configuration. If 

multiple B426 modules reside on the same system, each B426 module 
must have a unique address.

3.4 | Wire to an option bus control panel

Run the wires from the module to the data bus terminals on the 

compatible control panel. Refer to 

Figure 3.2

.

4 | Configuration

Configure the B426 using one of the methods described in this section 

for your control panel type.

NOTICE!

By default, when connecting a field replacement B426 to an 

existing SDI2 Control Panel, the panel overrides the module 

settings. To keep custom module settings when you connect 

a module to a configured SDI2 control panel, you must 

disable Panel Programming using web-based configuration, 

prior to connecting to the SDI2 bus.

An SDI2-compatible control panel automatically configures a newly 

connected module.

1. 

Ensure the B426 is new, or defaulted to the factory settings.

2.  Set the address switch to the correct address for the control panel 

(SDI2 control panels use address 1 or 2).

3.  Program the control panel communication settings using RPS or the 

keypad.

4.  Connect the module to the control panel bus and apply power.

NOTICE!

Before proceeding, ensure that the web browser is not 

configured to use a proxy server. Refer to the browser’s 

online help for instructions on disabling proxy service.

4.1 | Configure an SDI2 control panel

4.2 | Configure an SDI, option bus control panel

Configure for an SDI or option bus control panel using one of the 

methods described in this section.

4.2.1 | Plug and Play configuration

When installing under the following conditions, the B426 needs no 

further configuration:

 

DHCP is available on your network.

 

AES encryption is not required.

 

Default B426 port settings (UDP on Port 7700) are permitted by 

the network administrator.

4.2.2 | Web-based configuration

For installations where additional non-default settings are required, a 

web-based configuration menu is available.

 

Determine the module’s hostname or IP address by one of the following 

methods:

 

Locate the IP address in the table on the DHCP server 

(networked modules).

 

Use Auto IP to direct connect from your PC to the B426. 

Within 60 seconds, the B426 temporarily assumes address 

169.254.1.1 for configuration. (

Refer to the Conettix Ethernet 

Communication Module Installation and Operation Guide

 for more 

information on using these methods.)

To use web-based configuration (B426 configuration web pages):

1. 

Open an internet browser (Microsoft Internet Explorer 6 or 

higher, or Mozilla Firefox 3 or higher) and type in the B426’s IP 

address. The B426’s login page opens.

2. 

Enter the default password:

control panel shown)

NOTICE!

The module reads the address switch setting only during 

power up. If you change the switches after you apply power 

to the module, you must cycle the power to the module in 

order for the new setting to be enabled.

One address switch determines the address for the B426 Conettix 

Ethernet Communication Module. The control panel uses the address 

for communications. Use a slotted screwdriver to set the address 

switches.

The B426 address switch provides a ones value for the module’s 

address. 

Figure 2.1

 shows the address switch setting for address 1.

Option

The B426 Ethernet Communication Module is a four-wire powered SDI, 

SDI2, or Option bus device that provides two-way communication with 

compatible control panels over IPv4 or IPv6 Ethernet networks. 

The B426 on-board switch determines the bus address of the device. 

Configuration of the B426 is performed through the B426 configuration 

web pages. On SDI2 control panels, configuration can also be done on 

the keypad or through Remote Programming Software (RPS).
