Connecting to the SSA-324

General Description

The SSA-324 is a System-to-System Adapter (or interface). It interconnects the voice signals between different types of
intercom systems. In addition, it can optionally interconnect intercom systems. Also, it can optionally interconnect "Calls" or
tally signals between systems. Each SSA-324 includes two, 2-wire to 4-wire converters. The 4-wire interface can deliver and
accept high-level signals such as those from the McCurdy intercom system. An SSA-324 carries two voice channels when
used as dual 2-wire to 4-wire interfaces, and one voice channel when functioning as a 2-wire to 2-wire interface.

Installation

Mechanical Installation

The SSA-324 can be installed in 3 ways:
• a single unit mounted in half rack space using an optional Model MCP2 Kit for rack mounting a single unit.
•
two SSA-324 power supplies mounted side-by-side using the optional MCP1 Kit for rack mounting two units side-by-side.
• free standing using the optional MCP8 Kit for adding side channels for non-rack mounting portable use.

Electrical Installation

The connection for t6he headset used to setup the interface is on the front panel, all other connections are on the rear panel.
On the rear panel, on System A the 2-wire connection is at J101, while on System B it is a J102. These are XLR-3-31 (female)
type connectors. System A and B 4-wire connections are both at TB1 and J103. J103 also contains connections to the options
card, when installed. Low voltage alternating current power is applied to J104 (16 volts, AC).
