General Information
The Model 12594-001 Redundant AZI Switching Module is designed to provide connection for a primary
and a secondary AZI card when redundant circuits are required in GAI-Tronics ADVANCE cabinets or
oth er au dio swit chin g applications. The module controls audi o line s w itch ing from the AZI cards t o
amplifier inputs. Each module is capable of switching six audio lines. The switching action is controlled
by an external contact closure.

Installation
CAUTION
When instal ling o r replacing this mod ul e, be sure power is not app l ied to
avoid damage to the module circuits.
The Model 12594-001 Redundant AZI Switching Module is designed for mounting in 4-inch Snap Trak
When inserting the module in SnapTrak
®
, exercise care when pressing on the module edges to avoid
®
dama ge to the module’s pr inted circuit board and compon e nts.
Once installed in the SnapTrak
®
, be sure the module edges are secured in the channels so that the module
does not dislodge during transport or operation if subjected to vibration. Also, if this module is used with
other modules in the SnapTrak
®
, be sure to leave spacing between modules to facilitate wiring at any
edge-mounted terminal blocks.
Terminations
The following is a description of the available terminations:
J1 – is the primary AZI card connection; a cable with a 25-pin “D-Sub” connector is required.
J2 – is the secondary AZI card connection; a cable with a 25-pin “D-Sub” connector is required.
JTB1 – is the 12 V dc power input to the module.
JTB2 – is a feed-through 12 V dc power output to other modules.
JTB3 – is the secondary RS-485 data connection.
.
JTB4 – is for the six switched, audio outputs.
JTB5 – is the primary RS-485 data connection.
JTB6 – are the control inputs to the module to activate the relays to switch between primary and
secondary AZI cards when a fault occur s . Activation at either inpu t requires dc (-) contro l.
JTB7 – is the Form “ C” dry c onta c t out put, which can b e u sed t o activat e other devices or for r e mote
status indication. The maximum switching capacity for the contact set is 30 V dc @ 1 amp.
JTB8 – is an au xiliary audio outp ut connection from the AMP-6 output of the primary AZ I card that ca n
be used to supply audio signals to other devices, if needed.
JTB9 – is an au xiliary audio outp ut connection from the AMP-6 output of the secondary AZI card that
can be used to supply audio signals to other devices, if needed.
