SSM101 Card Rack Assembly
General Information
This data sheet applies to the Model SSM101 Card Rack Assembly, which is a central control device
designed to control a single-zone SmartSeries system and central amplifiers. This system configuration
provides health checking (supervision) for the Page/Party® system’s page line and party line 1 cable,
handset/speaker amplifiers and station speakers. Additionally, it allows the ability to connect up to seven
power amplifiers for central amplifier page broadcast.
SmartSeries handset stations and power amplifiers permit the operator to page individuals throughout the
system. Additionally, two-way (telephone type) conversation can occur between stations on a party line.
Single party line systems and five party line systems are available. Refer to Figure 1 for typical system
diagram.

Capacities/Limitations
SmartSeries Stations—A maximum of 200 SmartSeries stations may be connected to the PPI card in the
SSM101 Card Rack.
Speakers—Only one speaker can be connected to a SmartSeries station if the station is supervising the
speaker. If speaker supervision is not used, up to four speakers can be connected to a single station.
Central Power Amplifiers—A maximum of seven central power amplifiers may be connected to the AZI
card of the SSM101 Card Rack.
Central Power Amplifier Input Cable—One No. 18–20 AWG shielded, twisted pair cable is required for
each amplifier.

GAI-Tronics System Cable—The recommended maximum cable distance from the card rack to a
SmartSeries station is 5,250 feet (1600 m).
GAI-Tronics Speaker Cable—The recommended maximum cable distance from a SmartSeries station to
an 8-ohm speaker is 75 feet (22.86 meters). The maximum cable distance from a SmartSeries station to a
16-ohm speaker is 150 feet (45.72 meters).
The following printed circuit boards are included:
Master Control Unit (MCU)—Contains the central processing unit that coordinates all system operations
as defined by its software configuration. The MCU maintains communication with all other cards in the
card rack and with SmartSeries stations and devices located throughout the system.
Page/Party® Interface (PPI)—Provides system interface for SmartSeries and Page/Party®. Each PPI card
supports up to 200 SmartSeries stations and an unlimited number Page/Party® stations.
Amplifier Zone Interface (AZI)—The AZI is the interface to the central amplifiers. Each SSM101
supports up to seven amplifiers and provides a serial data port for connection of MRM and ADM devices.
The Model PA250-001 250-Watt Central Power Amplifier is designed for use in public address systems.
It can be mounted in standard 19-inch racks or placed on a table. It is designed to be connected to 8-ohm
speakers via the direct 8-ohm connection, or connected to speakers with variable-impedance, line matching
transformers designed to match the amplifier’s line output voltage of 25 V or 70.7 V.
Optional Ancillary Equipment
The Model 10959-103 Audio Messenger Interface (AMI) tone/speech generator broadcasts live pages,
pre-recorded alarm tones, and pre-recorded speech messages. The included Audio Messenger Interface
Configuration Tool (ACT) software is used to define and change configurations for the AMI. The AMI
includes eight configurable inputs and outputs. The AMI provides the ability to perform live speech pages
from a telephone if connected to an analog station port of a PBX type telephone system, or directly to a
Central Office telephone line on the public switched telephone network (PSTN). The AMI includes a builtin feedback eliminator. The Model 10959-103 includes a Page/Party® system interface card.
The Model 10434-202NA Building Entrance Protection Barrier provides secondary protection
from signal line transients and over-voltage conditions that may cause serious damage to indoor
equipment or injury to personnel.
