TOA Electronics EX-16 - Manual (Page 3)

1. Introduction
This is the installation manual for the exchange, stations and other
components of TOA Intercom System EX-16. It includes an outline of the
system, an explanation of installation, cable connection, inspection
procedures and a troubleshooting guide. Careful study of this manual
is recommended prior to installation of the system.
This manual is only intended to give the information necessary for
proper installation of the system.
Prior to installation of the system, unpack the components of the
system to make sure that they are in order.
2. Introduction of the EX-16 System
Because the EX-16 System is a fully electronic intercom system, it has
the following features that surpass conventional mechanical systems.
1. All components of the exchange are designed according to the
modular concept. Each module and the integral terminals for
connecting stations are connected to the mother board, thus
eliminating wiring between the two, resulting in a sizable reduction in
the number of procedures required to install the system.
2. The exchange is a wall-mounted type for space conservation.
3. Wiring for each station is an independent 4-wire system which uses
a minimum number of connecting wires resulting in greater ease
in installation.
2.1 Exchange
2.1.1 Features
The features of the TOA EX-16 Intercom System are as follows:
1. All components of the exchange are designed as plug-in modules.
This results in a great increase in ease of maintenance, expansion,
and in speed of the system installation.
2. Extensive incorporation of IC's in the electronic circuits of the
exchange results in a highly compact, space-saving design and in
quieter operation than conventional intercom systems.
The system consists of only two types of basic electronic units.
This, in turn, means greater freedom in selection of an installation
site.
3. Since the system is completely electronic, power consumption is
kept to a minimum.
