General Information
NOTE: If the 69268-001 Amplifier Zone Interface II (AZI II) board is being installed in a system that
does not currently have an AZI II, the GAI-Tronics Service Department must be contacted to modify the
system configuration. If the AZI II Board is being installed as a replacement for an existing AZI II,
follow the instructions contained in this manual. The 69268-001 AZI II board is designed to be installed
in the 10457 Series Card Rack Assembly and is used to interface between a 69254 Series or 69440 Series
Master Control Unit (MCU) and up to twelve power amplifiers.
How to Use the Assembly/Model
Application
The AZI II Board serves the following functions:
• Performs audio switching of the backplane page resources to the power amplifiers. There are two
page resources or buses available in the 10457 Series card rack.
• Performs audio switching from the backplane Supervisory Tone resource to the power amplifiers.
The Supervisory Tone permits health check monitoring of the power amplifiers’ speaker loops. The
supervisory tone incorporates gain control.
• Provides an audio path from the backplane Fail-safe Bus Tone to the power amplifiers.
• Provides normal/emergency output level selection for each of the two backplane page resources.
Each level is manually adjustable through the front bezel. The MCU controls output level selection.
• Provides manually-adjustable gain on two of the twelve outputs. The Amplifier 6 and Amplifier 12
outputs incorporate gain control.
• Provides RS485 communication to external Snaptrack™ modules.

Interfaces
Figure 2 illustrates the location, method of connection, and part numbers associated with the installation
of the AZI II board.
Figure 2. AZI II PCBA (69268-001) Interfaces
P1
P1 interfaces the AZI II board to the backplane on the 10457 Series Card Rack. This connector provides
the board’s digital I/O as well as power input. In addition, all of the audio buses are interfaced through
P1.
P2
P2 provides an audio interface to support up to 12 central amplifiers. It also provides an RS485 interface
to enable communication with external Snaptrack™ modules.

Installa tion/Repl acement
Warnings: Please observe the following warnings, or damage to the equipment may r esult.
WARNING:
Observe precautions for
handling electrostatic
sensitive devices.
1. Remove the AZI II board from its carton. Ensure that power is disconnected from the card rack
assembly.
2. Before installation, set hex switch S1 (Board Address) and hex switch S2 (Board ID) as shown in the
system manual.
• The valid range of Board IDs is: 0x1 to 0xE (hex)
• The valid range of Board Addresses is: 0x200 to 0x3F0 (hex)
The following is an example of a Board Address and how it is derived:
Sample Board Address: 2 E 0
• The first digit must always be either a 2 or a 3. This corresponds to whether W1 is installed
(2), or is removed (3).
• The second digit is set by switch S1. It is a hexadecimal number ranging from 0 to F.
• The third digit is always
zero.
3. Remove existing AZI II board from card rack assembly.
4. Align the new AZI II board into the upper and lower tracks for the slot.
5. Slide the card towards the rear of the card rack assembly until the board comes in contact with the
backplane connector.
6. Firmly press on the front bezel until the board is seated.
7. Secure the board to the card rack assembly by tightening the two screws located on the front bezel.
(See Figure 1.)

8. Apply power to the card rack assembly. You can expect to see the following responses on the AZI II
board:
These responses are summarized in the table below:
LED Color LED State Condition
ON-LINE
Green On/Off After a brief delay, the ON-LINE LED illuminates.
On indicates AZI II board is powered and recognized by MCU.
RTS
Yellow Flashes The RTS LED begins flashing continuously if external
modules are configured to communicate with the AZI II board.
Flashing indicates that the AZI II board is transmitting data via
RS485.
(The LED is on
when transmitting, and off when not
transmitting. The rapid switching between these two
conditions results in flashing.)
EOL
FAULT
Red On/Off The EOL
line (EOL) external modules are responding to the AZI II
FAULT LED does NOT illuminate if all the end-of-
Board.
ON indicates an EOL device is not responding. LED is
extinguished when all EOL devices respond to MCU.
9. Verify the AZI II Board properly routes audio and communicates with the external devices as
indicated in the system manual.
10. Adjust the normal level during a period when audio is routed via the AZI II board and normal
volume level is selected by the MCU. The volume control labeled NORMAL
LEVEL is located on
the AZI II front bezel. Rotate clockwise to increase the normal level.
11. Adjust the emergency level during a period when audio is routed via the AZI II board and emergency
level is selected by the MCU. The volume control labeled EM ERGENCY
LEVEL is located on the
AZI II front bezel. Rotate clockwise to increase the emergency volume.
12. Specific audio levels for the Amplifier 6 output and the Amplifier 12 output can be set independently
from the remaining ten amplifiers. If they are used, adjust the audio output levels of Amplifier 6 and
Amplifier 12 while audio is routed via the AZI II board. There are two user adjustments labeled as
AMP 6
VOL and AMP 12 VOL on the AZI II board. Rotate the corresponding volume control
clockwise to increase volume.
13. Specific audio level for the supervisory tone can be adjusted for all amplifiers simultaneously. R157
can be used to raise or lower the supervisory tone level. Rotating the pot clockwise will increase the
level.
14. The start-up and check-out are now complete.
