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.
The Model 12593-101 Redundant PPI Switching Module is designed for mounting in 4-inch Snap Trak
When inserting the module in SnapTrak

Once installed in the SnapTrak
to avoid damage to the module’s printed circuit board and components.
, 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 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.
®
J3 – is the output connection to the Page/Party
Cat5E cable is required.
TVP connection module; a standard straight through
.
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.

Address Switch Settings
Address switches S1 and S2 on the upper CPU PCBA must each be set to position F for a board address
of FF. When using multiple modules, address FF must be set on ALL modules. Address FF allows the
module to operate as a Multi-Station Simulator (MSS), with its designated PPI cards. Refer to the
operation section for information on the MSS feature.

Operation
The module switches the SmartSeries Page/Party® Stations between the Page/Party® Interface (PPI) cards
in the primary and secondary card racks. The switching action is initiated whenever a primary control
care or primary AMI fault occurs in the system. The signals being switched are the page line, party line
1, party line 2 and the control input (CLS).
The module has essentially two modes of operation, normal and fault. Each mode is described in detail
below.
Normal Co ndition
Connecting the Control Input (TB2) to dc ground will energize all relays on the module. LED1 (AActive) will illuminate to indicate the Primary system is active. The SmartSeries Page/Party
®
stations
(J3) are connected to the Primary PPI card (J1) via relays K3-K6.
The module’s CPU PCBA, is connected to the page line of the Secondary PPI card (J2) via relay K2. The
CPU PCBA simulates all the SmartSeries Page/Party
®
stations by responding to all station polling
requests from the Secondary Master Control Unit (MCU). This action prevents SmartSeries station faults
from occurring in the secondary system.
Fault Condition
The dc ground is removed from TB2 during a fault condition. LED2 (B-Active) will illuminate to
indicate the Secondary system is active. Relays K1–K7 are de-energized. Relay K1 contacts are wired to
TB3 and will change state for the duration of the fault condition. Relays K2–K6 switch the SmartSeries
Page/Party
®
stations (J3) to the Secondary PPI card (J2). The CPU PCBA is connected to the page line of
the Primary PPI card (J1).
Maintenance
If the module requires service, contact your Regional Service Center for a return authorization number
(RA#). The module should be shipped prepaid to GAI-Tronics with a return authorization number and a
purchase order number. If the module is under warranty, repairs or a replacement will be made in
accordance with GAI-Tronics’ warranty policy. Please include a written explanation of all defects to
assist our technicians in their troubleshooting efforts.
Call 800-492-1212 inside the USA or 610-777-1374 outside the USA for help identifying the Regional
Service Center closest to you.

Troubleshooting
Problem Solution
SmartSeries station faults are
present in the secondary system.
SmartSeries stations squeal
when party line 1 or 2 are
accessed.
Module LEDs do not illuminate
and relays do not switch when
input control is provided.
Module still does not function after
all checks described in this section.
Specification s
Electrical
Verify 12 V dc power is applied to the module.
Verify CPU PCBA address is set to FF.
Verify cables are properly inserted into connectors J1, J2, J3.
Ensure pins of CPU PCBA are correctly inserted into J4 of
lower relay switching PCBA.
Verify connectors J1, J2, J3 are properly inserted. If
disconnected, the page, and party lines 1 and 2 will be unloaded
resulting in oscillation of the SmartSeries handset amplifier.
Verify 12 V dc power is applied to the module.
Verify 12 V dc (−) is being switched to the C
ONTROL inputs
at TB2.
Contact GAI-Tronics service for repair or replacement of the
module.
