IMPROVEMENT OF REQUIREMENTS FOR WIRING SYSTEMS FOR FIRE PROTECTION SYSTEMS

Abstract

The whole complex of fire protection must work as a single system, be serviceable and kept in constant readiness for work, have a certain margin of safety for reliable operation in extreme conditions and long-term autonomy.

In general, the limits of fire resistance of cable systems or their fire protection systems, set in the state building codes DBN B.2.5-56:2014 and DBN B.2.5-23-2010, differ from those set in European and relevant national standards. At the same time, the limits of fire resistance for these systems set in such documents may not be sufficient to ensure that fire protection systems perform their functions.

Recently, a number of new versions of European standards have been adopted, in particular on the basis of international standards, which define new requirements for wiring systems for fire protection systems.

To eliminate discrepancies in the requirements of state building codes and national standards, requirements for fire resistance of cable lines for implementation in the national regulatory framework were formulated in order to adapt them to the requirements of European Union legislation and European standards.

In this regard, it is important to study the current requirements for wiring systems for fire protection systems justification based on the results of analytical studies of the requirements for such systems.
