1 | Overview

2 | SDI2 address settings

The module’s switches provide a tens and ones value for the 

module’s address. For single-digit address numbers 1 through 

9, set the tens switch to 0 and the ones digit to the appropriate 

number. The following illustration shows the address switches 

setting for addresses 1 and 11.

Set the switches per the control panel configuration. Each 
B308 module must have a unique address.

3.1 | Install the module in the enclosure

Refer to the following illustration for installing into the enclo-

sure.

3.2 | Install and wire the tamper switch

You can connect an optional enclosure door tamper switch 

for one module in an enclosure. 

1.  Put the ICP-EZTS Tamper Switch (P/N: F01U009269) 

into the enclosure’s tamper switch mounting location. 

For complete instructions, refer to 

EZTS Cover and Wall 

Tamper Switch Installation Guide

 (P/N: F01U003734).

2.  Plug the tamper switch wire onto the module’s tamper 

switch connector.

3.3 | Attach to the control panel

Use either the module’s terminal strip labeled with PWR, A, B, 

and COM, or the module’s interconnect wiring connectors (wire 

included) to attach to the control panel. Interconnect wiring 

parallels the PWR, A, B, and COM terminals on the terminal 

strip. Refer to the following illustrations for wiring.

NOTICE!

Use the terminal strip wiring 

or

 interconnect wiring 

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

connecting multiple modules, combine terminal strip 

and interconnect wiring connectors in series.

To find the output numbers for each address, multiply the 

address number by 10 for the base number, and then use 

numbers 1 through 8 in the ones place for the output numbers. 

For examples, refer to 

Section 8

.

This module is a supervised device that provides 8 

programmable outputs (Form C relays) and connects to control 

panels through the SDI2 bus.
