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.

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.

.
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.

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 us ing mu ltiple modules, address FF must be set on ALL modules. Address FF allows the
module to operate as a Multi-S tation Simulator (MSS), with its d esignated P PI car ds. Refer to the
oper atio n section for information on the MSS feature.
Operation
The module switches the SmartSeries Page/Party® Stations between the Page/Party® Interfac e (PPI) cards
in th e p rima ry and seco ndary card rac ks. The switching action is in itia ted wh e never a primary MCU or
primary AMI fault occurs in the system. The signals being switched are the page line, party lines 1 and 2,
the r e lay contr ol output (R LY) and t he control input (CL S).
The module has essentially two modes of operation, normal and fault. Each mode is described in detail
below.
Normal Co ndition

All relays on the module are de-energized. The SmartSeries Page/Party
the P rimary PPI card (J1) via relays K2 - K6.
stations (J3) are connected to
The module’s CPU PCBA, is connected to the page line of the Secondary PPI card (P2) via relay K7.
The CP U P CBA simulat es 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 C onditio n
A fault condition is signaled by connecting either terminal of JTB4 to dc ground. LED1 (Pri-Active) or
LED2 (Sec-Active) illuminate to indicate the active input. In an ADVANCE system application, these
inputs are active if a primary MCU or primary AMI fault occurs. The control signal input is supplied by
an external relay contact.
When activated, relays K1–K7 are energized. Relay K1 contacts are wired to JTB1 and will change state
for the duration of the active 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
(P1).

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 r e lays do not s witch when
input control is provided.
Module still does not function after
all checks described in this section.
• 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 J1 pins of CPU PCBA are correctly inserted into J4 of
lower relay switching PCBA.
• Verify connectors J 1 , J2, J3 are properly ins erted. If
disconnected, the page, and party lines 1 and 2 will be
unloade d resu lting in osc illation of the Smar tSer ies handset
amplifier.
• Veri fy 12 V dc (-) is being switched to the PRI
and/or SEC
inputs at JTB4
Contact GAI-Tronics service for repair or replacement of the
module.
