General Information
The Model 12593-001 Redundant PPI Switching Module is designed to provide connection for a primary
and a secondary PPI card when redundant circuits are required i n GAI-Tronics ADVANCE cabinets. The
module controls audio line switching from the PPI cards to SmartSeries Page/Party

Hardware Configuration
The Model 12593-001 Redundant PPI Switching Module is comprised of two printed circuit board
assembli e s (PCBAs). The lower b ase board conta ins the lower switc hing rela ys and measures 7.5 L × 4
W inches (190.5 × 102 mm). The r e lay swit chi n g PCBA is equipped w ith seven sma ll DPD T relays, two
LEDs, three 25-pin “D” connectors and four modula r (plug -in type) terminal blocks .
The upper CPU PCBA emp loys a micro-contr oller and ha s two a ddr es s switches (S1 and S2) . The s mall
terminal block located on the opposite side is for external power when used in other applications when
power is not available via the 34-pin DIP connector (J1).
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 12593-001 Redundant PPI Switching Module is designed for mounting in 4-inch Snap Trak

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 Model 12593-001 Redundant PPI Switching Module is equipped with three 25-pin “D” connectors,
and four modular (plug-in type) terminal blocks, which simplify external connections during installation,
and provide quick disconnect if replacement is ever required.
The following is a breakdown of each connector and terminal block and its function(s):
J1 – is the primary PPI card connection; a cable with a 25-pin “D-Sub” connector is required.
J2 – is the secondary PPI card connection; a cable with a 25-pin “D-Sub” connector is required.
®
J3 – is the output connection to the Page/Party
connector is required.
TVP connection module; a cable with a 25-pin “D-Sub”
.
JTB1 – is the f orm “C” dry contact output, whic h c an be used t o activat e additiona l swit chin g modu les,
or for remote status indication. The maximum switching capacity for the contact is 30 V dc @ 1 amp.
JTB2 – is a feed-through 12 V dc power output to additional switching modules.
JTB3 – is the 12 V dc power input to the module.
JTB4 – are the control inputs to the module to activate the relays to switch between primary and
seco ndary PP I cards, whe n a fa ult occurs. Activation at either input r equires dc ground control.
