Bosch B208 - I/O System Installation Manual

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.

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 configuration. 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.

Figure 2.1: Address switches

Valid B208 addresses are dependent on the number of points allowed by a particular control panel. Addresses higher than 32 require B208 firmware 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.

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.

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

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.

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.

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.

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. Run wires away from the premises telephone and AC wiring. For the 1 kΩ dual EOL resistor circuit style order ICP-1K22AWG-10, a package of 10 1.0 kΩ EOL resistors.

1. Point sensor loop terminals
2. Normally closed device (contact)
3. 1 kΩ resistor at device
4. 1 kΩ resistor at end-of-line (EOL)
5. Normally open device (contact)

Dual EOL requires B208 firmware v1.05.001 or higher. Dual EOL meets the requirement of double protection for medium to high risk ULC installations.

LED descriptions

The module includes one blue heartbeat LED to indicate that the module has power and to indicate the module's current state. Refer to Table 4.1.

Table 4.1: LED descriptions

Flash Pattern	Function
Flashes once every 1 sec	Normal state: Indicates normal operation state.
3 quick flashes every 1 sec	Communication error state: Indicates (the module is in a "no communication state") resulting in an SDI2 communication error.
ON Steady	LED trouble state: Module is not powered (for OFF Steady only), or some other trouble condition prohibits the module from controlling the heartbeat LED.
OFF Steady

Show the firmware version

To show the firmware version using an LED flash 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 flash pattern
  
  Figure 5.1: Firmware LED flash patterns

When the tamper switch is activated, the heartbeat LED stays OFF for 3 seconds before indicating the firmware version. The LED pulses the major, minor, and micro digits of the firmware version, with a 1 second pause after each digit. In the following example, the version 1.4.3 shows as LED flashes:
[3 second pause] [3 second pause, then normal operation].
