LOUD-SPEAKING COMMUNICATION SYSTEM (LSCS) read more PDF 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. SPECIFICATION
