General Information

The Model 12593-101 Redundant PPI Switching Module is designed to provide connection for a primary
and a secondary PPI card when redundant circuits are required in GAI-Tronics ADVANCE cabinets. The
module controls audio line switching from the PPI cards to SmartSeries Page/Party
module is capable of switching one zone. The switching action is controlled by an external contact
closure.

Hardware Configuration

The Model 12593-101 Redundant PPI Switching Module is comprised of two printed circuit board
assemblies (PCBAs). The lower base board contains the switching relays and measures 4 L  4 W inches
(102  102 mm). The relay switching PCBA is equipped with six small DPDT relays, two LEDs, three
RJ45 jacks and three modular (plug-in type) terminal blocks.

The upper CPU PCBA employs a micro-controller and has two address switches (S1 and S2). The small
terminal block located on the opposite side is for external power when used in other applications.

Installation

CAUTION

When installing or replacing this module, be sure power is not applied to

avoid damage to the module circuits.

Terminations

The Model 12593-101 Redundant PPI Switching Module is equipped with three RJ45 jacks and three
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 standard straight through Cat5E cable is required.
J2 – is the secondary PPI card connection; a standard straight through Cat5E cable is required.

TB1 – is the 12 V dc power input to the module.
TB2 – is the control input to the module to activate the relays to switch between primary and secondary

PPI cards.

TB3 – is the form “C” dry contact output, which can be used to activate additional switching modules, or

for remote status indication. The maximum switching capacity for the contact is 30 V dc @ 1 amp.
