Bosch D7212GV4K7 Installation Manual

1 | Overview

The B208 Octo-input Module is an 8 point supervised expansion
device that connects to control panels through the SDI2 bus.
This module communicates back to the control panel all point
status changes. The inputs are accessed through on-board screw
terminal connections.

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.

CAUTION!

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

(to control panel or additional modules)

(to control panel or additional modules)

6 ― Address switches

2 | SDI2 address settings

Two address switches determine the address for the B208
Octo-input Module. The control panel uses the address for
communications. The address also determines the output
numbers. Use a slotted screwdriver to set the two address
switches.

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 to enable the new setting.

Set the address switches per the control panel confi guration. If
multiple B208 modules reside on the same system, each B208

module must have a unique address.

The module’s address 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. Figure 2.1 shows the address switches
setting for addresses 1 and 11.

2.1 | Valid addresses and input numbers per
control panel

Valid B208 addresses are dependent on the number of points
allowed by a particular control panel. Addresses higher than 32
require B208 fi rmware version 1.03.003 or higher.

To determine the point 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 point numbers.
For examples, refer to Section 8.

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.

Callout ― Description

1 ― Module with mounting bracket installed

2 ― Enclosure

3 ― Mounting screws (3)

3.2 | Mount and wire the tamper switch

You can connect an optional enclosure door tamper switch
for one module in an enclosure.
Installing the optional tamper switch:

1. Mount 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. Refer to Figure 1.1.

3.3 | Wire to the control panel

When you wire the module to a control panel, you can use either
the module’s terminal strip labeled with PWR, A, B, and COM,
or the module’s interconnect wiring connectors (wire included).
Interconnect wiring parallels the PWR, A, B, and COM terminals
on the terminal strip. Figure 1.1 indicates the location of both
the terminal strip and the interconnect connectors on the
module.

Refer to Figures 3.2, 3.3, and 3.4.

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.

3.4 | Sensor loop wiring

Wire resistance on each sensor loop must be less than 100
Ω with the detection devices connected. The terminal strip
supports 12 to 22 AWG (0.65 to 2 mm) wires.
The B208 detects open, short, normal, and ground fault circuit
conditions on its sensor loops and transmits the conditions to
the control panel. Each sensor loop is assigned a point number
and transmits to the control panel individually.

that the module has power and to indicate the module’s
current state. Refer to Table 4.1.

other trouble condition prohibits the
module from controlling the heartbeat
LED.

5 | Show the fi rmware version

To show the fi rmware version using an LED fl ash pattern:

- If the optional tamper switch is installed:
With the enclosure door open, activate the tamper switch
(push and release the switch).

- If the optional tamper switch is NOT installed:
Momentarily short the tamper pins.

Refer to Figure 5.1 for an example of fl ash pattern

s.

Figure 5.1: Firmware LED fl ash patterns

When the tamper switch is activated, the heartbeat LED
stays OFF for 3 seconds before indicating the fi rmware
version. The LED pulses the major, minor, and micro digits of
the fi rmware version, with a 1 second pause after each digit.

In the following example, the version 1.4.3 shows as LED
fl ashes:
[3 second pause] *___****___*** [3 second pause, then
normal operation].
