Intercom divers station SVS-2P-ÌS is designed for maintenance of loud-speaking double-end telephone communication either in the 2- or 3- wire mode between:
High communication quality is provided by:
- The operator and one or two divers, either operating under water or situated in decompression chamber,
- For divers communication among themselves and with the operator.
Besides, the station has possibility to:
- suppression of network frequency and multiple harmonics that is especially important at carrying out of underwater welding,
- existence of protection from pickups and wandering currents,
- optimization of speech path frequency characteristic which has raised legibility of speech;
- suppression of noise from air (incoming and outgoing from helmet);
- automatic amplification adjustment that keeps the established loudness of sound, both for operator,
and for divers invariable;
High reliability of station SVS-2P-MS is provided by:
- output of talks with all subscribers on a separate socket for tape recording;
- connect portable (deck) loudspeaker by capacity 10 W;
- works with various types of communication cables;
- operation without reconfiguration of both low- and high-resistance communication headsets;
- power source both from external sources 220V 50Hz or 12 – 24V DC and built-in accumulator. At fall of external power source the station automatically switches to the built-in accumulator without interruption in communication. Light indication of power source’s switch and charge level of built-in accumulator is provided in station;
- possibilities for carrying out the operative wire and headset diagnostic in case of communication interruption with diver (breakages, short circuits and cable or headset wicking);
- possibilities for surface operator to work without the portable console, instead of it to use the loudspeaker as a microphone (loudspeaker is integrated in the obverse panel);
Modular construction makes it possible to repair the system in field conditions or on the side of the Customer by replacing the failed PCBs with new ones without soldering and additional configuration of the replaced module.
Station SVS-2P-MS is produced in the shockproof water-proof case. Design features allow to use station both in portable and stationary variants.
