 The LSCS is intended for maintenance of simplex loud-speaking communication between the removed from each other systems.

Communication between equipment LSCS is carried out in any combination by two-wire and four-wire lines or phone channels of automatic telephone exchange (ATE).

It is one of components of operatively-technological communication system and can be used everywhere, where there is a necessity of people communication, connected by a uniform technological chain: in the industrial enterprises, in administration building, station and entertaining complexes, offices and etc.

Two modifications of the loud-speaking equipment are produced:

• LSCS-1, used at a single-channel two-side loud speaking communication

 LSCS-8 –equipment providing 8 channel loud speaking communication 

       

LSCS provides:

• Transmission from built-in or external noise-resistant microphones with the indicating lamp for transmission mode turning on;
• Transmission reception on the built- in loudspeaker of the device and/or an external active loudspeaker with the possibility of loudness level control. Information reception is made at the released button or talk-listen button;
• Automatic transition on DC supply (accumulator) with the 12V voltage at switching-off of AC network;

 LSCS — 8 has conference communication mode between channels.

Commutator is intended for commutation of N-phones of central battery (CB) system and connection of its subscribers to one urban telephone line.

The commutator operates by three mode:

•  N pones of CB system;
• spreading (coupled operation of two switchboards for the purpose to increase  number of subscribers  of the CB system);
• conference communication (connecting all subscribers to one line).

The device consists from:

• commutator with handset set and dialer for CB system;
• linear dashboard  for subscribers  connection.

The call from subscribers is displayed by light-emitting diode indication and the sound alarm system. 

Commutation of subscribers is carried out by microswitcher.

Supply from alternative current	~220V
Overall dimensions	385x200x85 mm

The compressor is intended for matching of digital channel of communication  with various  communication lines.

Consists from:

• digital linear modem;
• matching unit (MU).

The equipment provides:

• multiplexing of 4 digital flows with 22 kbit/s speed in one general flow under the standard RS 232;
• joining each channel;

a) by two-wire line;

b) by four-wire line;

c) by telephone two-wire line;

d) by port RS 232.

The system is intended for sounding and providing of the simultaneous translation of interpreters and tour guides operating both indoors and outdoors modes.

This system provides the necessary level of quality of meetings, conferences and trips.
Advantages of this system are small dimensions and weight, and also operative preparation of system for operating.

The equipment consists of:

• central unit;
• microphone for the interpreter or guide;
• extension cord (with 10м of cable length  with  4-socket-outlets for plugging the earphones after each 1m);
• earphones.
