SLS-15 Shaft Communication System
The SLS-15 system is a means of shaft telephone communication designed to organize local communication in mine shafts where a methane hazard of any concentration may occur.
SLS-15 SHAFT COMMUNICATION SYSTEM
It is designed for use mainly in underground mines. It can be used in places at risk of methane and/or coal dust explosions, in places with high noise levels, salinity, dustiness or in high humidity conditions. It allows for telephone communication between the hoisting machine operator and the plant crew located at different levels, and also allows for the transmission of a threat report to the operator, the transmission of information or signals by the operator to threatened places or mutual communication of subscribers between levels.
The SLS-15 shaft communication system is made in an intrinsically safe version [I] intended for plants at risk of methane and/or coal dust explosions, and a non-intrinsically safe version [N] intended for other plants and places where intrinsic safety is not required.
The SLS-15 system, both in the intrinsically safe version SLS-15/I and the non-intrinsically safe version SLS-15/N, is a means of communication that guarantees compliance with the guidelines contained in Annex No. 2 to the Regulation of the Council of Ministers of 30 April 2004 on the approval of products for use in mining plants.
The system has the approval of the President of WUG No. GX-33/15
