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. 2.1.2 Specifications The exchange is available with the following specifications. EX-16 Capacity: 16 lines max. (with paging function) Dimensions: 360(W) X 300(H) X 100(D)mm (14.2" X 11.8" X 3.9") Weight: 8.3 kg (18.3 lbs.) with 16 lines Exchange capacity can be increased within the given limits in units of 4 lines. Exchange Specifications Ambient Temperature Range: 32°~104° F (0°~40°C) Audio Input Level: +7dBm max. Audio Output Level: +30dBm max. Bandwidth: 200Hz~10KHz Crosstalk: -60dB/1.5KHz Subscriber Impedance: 600 ohms balanced (input/output) Power Consumption: 30W Power Source: AC 110, 120, 220, 240V ±10% DC 24V 2.1.3 Further Details The exchange is composed of the following sections: * CPU (Central Processing Unit) * LAU (Line Amplifier Unit) * DSM (Power Supply Module) * Integral terminal board for connecting stations The power supply module can be removed ...
