Foreword
This document (EN 50491-6-1:2014) has been prepared by CLC/TC 205 "Home and Building Electronic
Systems (HBES)".
The following dates are fixed:
• latest date by which this document has to be
(dop) 2014-11-25
implemented at national level by publication of an
identical national standard or by endorsement
• latest date by which the national standards conflicting
(dow) 2016-11-25
with this document have to be withdrawn
This European Standard covers the Principle Elements of the Safety Objectives for Electrical Equipment
Designed for Use within Certain Voltage Limits (LVD - 2006/95/EC).
This European Standard is complementary to EN 50174-2, “Information technology – Cabling installation –
Part 2: Installation planning and practices inside buildings” – Clause 10 “Homes”. The couple of standards
constitute the reference for the installation requirements of the home network which includes the
telecommunications service distribution and the HBES.
This European Standard specifies the specific HBES installation requirements. EN 50174-2 gives the specific
ICT and BCT cabling installation and planning requirements.

1 Scope
This European Standard specifies the additional specific HBES requirements for the common rules for the
planning and the installation of HBES home cabling systems. The structure is in accordance with
EN 50174-2.
This European Standard focuses on requirements for HBES cabling systems in homes. Requirements for
backbones cabling in buildings are also considered.
HBES radio frequency (RF) systems are considered as extensions or as alternative to cabled systems.
RF connections may have an impact on the infrastructure. Different infrastructure models are presented for
the use of RF connections instead of wired ones (e.g. fewer installation spaces IS6).
Optical fibre HBES installation guidelines may be considered in future.
Power line systems are outside the scope of this European Standard.
