Bosch B308 - Octo-Output Module Installation Manual

Overview

This module is a supervised device that provides 8 programmable outputs (Form C relays) and connects to control panels through the SDI2 bus.

Callout ― Description

1. SDI2 interconnect connectors - connect SDI2 control panel and SDI2 devices
2. SDI2 terminal strip - connect SDI2 control panel and SDI2 devices
3. Tamper switch connector
4. Terminal strip (outputs)
5. Heartbeat LED (blue)
6. Address switches

SDI2 address settings

NOTICE!
The module reads the switch setting only during power up. Cycle the power to the module to enable the new setting.

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

Valid addresses and output numbers per control panel

Valid B308 addresses are dependent on the number of outputs allowed by a particular control panel.

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 "Point number examples".

Installation

Remove all power (AC and battery) before making any connections. Failure to do so might result in personal injury and/or equipment damage.

Install the module in the enclosure

Refer to the following illustration for installing into the enclosure.

Callout ― Description

1. Module with mounting bracket installed
2. Enclosure
3. Mounting screws (3)

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.

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.

Callout ― Description

1. Terminal strip wiring (SDI2)
2. Interconnect cable (P/N: F01U079745) (included)

Callout ― Description

1. Bosch control panel
2. B308 modules

Callout ― Description

1. Bosch control panel
2. B308 modules

Relay output wiring

Each output provides a NO and a NC output. The NO, C (COMMON), and NC terminals are available in each terminal or connection output position. The silkscreen on the edge of the circuit board shows the function of each terminal and the relay output number.
The middle terminal of each output position is the COMMON and is labeled C. When the output is inactive, the NC (Normally Closed) terminal has continuity with the C terminal. When the output is active (energized), the NO (Normally Opened) has continuity with the C terminal.
NOTICE!
Do not exceed relay contact ratings of 1.0 A, 24 VDC, resistive load.

LED descriptions

The module includes one heartbeat LED to indicate that the module has power and to indicate the module's current state. Refer to the following table.

Flash Pattern	Function
Flashes once every 1 second	Normal operation state.
3 quick flashes every 1 second	Communication error state: Indicates an SDI2 communication error.
ON Steady	LED trouble state: Not powered (for OFF Steady only), or some other trouble condition.
OFF Steady

Show the firmware version

With a tamper switch:

1. Open the enclosure door.
2. Push and release the switch

Without a tamper switch:

1. Quickly short the tamper pins.
2. Refer to the illustration below.

When the tamper switch is on, the heartbeat LED stays OFF for 3 second before showing the firmware version. The LED flashes the major, minor, and micro digits of the firmware version, with a 1 second pause after each digit.
For example, the version 1.4.3 shows as LED flashes: [3 second pause] *___****___*** [3 second pause, then normal operation].
