INTRODUCTION
A HBES/BACS network is part of the home/building network, which includes cabling for
information and communication technology (ICT) and broadcast communication technology
(BCT) applications. ISO/IEC 14763-2 is the specific standard for ICT and BCT cabling
installation and planning.
This document covers installation and planning requirements specific to a HBES/BACS network
in addition to safety requirements for electrical installations included in the IEC 60364 series.
Installation and planning specific requirements include:
– infrastructures for cabling,
– coexistence with electric wiring,
– hints for sensors.
Wireless systems are also considered. Planning the cabled backbone for wireless systems is
less complex compared to a full cabled network pathway, power supply cabling. Additional
provisions are provided to guarantee coverage and reliability.

4 Home/building networks
The home/building networks:
– ensure the distribution of services, such as:
• communication,
• HBES/BACS;
– need components such as conduits, boxes, etc. as physical infrastructures for the system.
The implementation of the home/building network goes through the following steps:
– design,
– planning of physical infrastructure,
– installation.
The planning of a common physical infrastructure for HBES/BACS, ICT, and BCT and the
supporting power distribution network is advantageous for the following reasons:
– cost optimization through common works,
– optimization of the pathways,
– planning of common installation spaces for interfacing units,
– simplify the planning of spaces for future updates.
Specific requirements for the planning and the installation of a communication services generic
cabling infrastructure are given in ISO/IEC 14763-2. Requirements for the HBES/BACS physical
infrastructure are given in this document.
HBES/BACS networks can be wired, wireless or a combination of both and require a supporting
physical infrastructure. For example, wireless HBES/BACS are composed of the housing of the
device, the supporting power network, the positioning of interfacing modules, etc.
– 10 – IEC 63044-6:2021 © IEC 2021
5 Home/building network model and general requirements
The design of the home/building network shall consider:
– characteristics of the premises, including surface, type of home/building, physical
characteristics;
– required services:
• communication,
• HBES/BACS (see IEC 63044-1 for the complete list of HBES services);
– possible restrictions, in the case of existing buildings (see Annex A).
Figure 1 shows that a star topology is commonly used for ICT and BCT cabling subsystems
(according to ISO/IEC 11801-1). The home distributor (HD) is the unit for service delivery to
outlets (TO: telecommunication outlets; BO: broadcast outlet). A secondary home distributor
(SHD) may be necessary in the case of complex premises (e.g. a home on two floors).
HBES/BACS networks may have different topologies: wired (e.g. bus, tree, loop, star and/or
combinations thereof), wireless or mixed wired/wireless. However, HD and SHD spaces may be
conveniently shared with ICT and BCT networks.
HD: Home distributor
SHD: Secondary home distributor
TO: Telecommunication outlet
BO: Broadcast outlet
Figure 1 – General topology of home/building network showing
ICT, BCT, HBES/BACS networks
Home/building applications may be distributed over the ICT network, and communication
services may have interfaces with HBES/BACS.
HBES/BACS networks may have outdoor parts.
NOTE Outdoor locations are for example front doors, garages, garden lighting.
Improvements and additions to the HBES/BACS may however occur during the building life
(e.g. change/addition of devices). Flexibility is therefore required for the home/building network
layout.
Wireless networks often need some wiring and spaces for housing devices which need
infrastructure planning as well. See Clause 6 for infrastructure planning either for wired or
wireless networks.
Some installation guidelines for typical HBES/BACS applications are reported in Annex B
depending on the applications and clusters of services for HBES/BACS provided in Annex E.
6 Infrastructure requirements
6.1 Infrastructure requirements for wired HBES/BACS
6.1.1 Installation spaces for wired HBES/BACS
According to the home/building network model of Clause 5, a physical infrastructure shall be
planned to allow the installation of cables and housing of the equipment.
Since the HBES/BACS may be extended to the whole building and to the outdoor grounds,
corresponding installation spaces shall be foreseen.
Six levels of installation spaces are identified, labelled IS1 to IS6 and selected according to the
design specification.
NOTE The selection of installation spaces depends on the complexity of the installation. For example, in a single
home installation only IS2, IS4, IS5 and IS6 are usually needed.
Installation spaces IS1 to IS6 are intended for fixing cabinets, enclosures and/or boxes, for
example according to IEC 60670-1 and containing active and/or passive devices as well as
connecting hardware.
Each installation space shall:
– contain boxes with an appropriate fixture for fixing the devices;
– allow mounting of active and passive (modular) devices, with any insulation and separation
that may be required;
– facilitate access for maintenance;
– allow foreseeable extensions of the network.
Figure 2 summarises the installation spaces IS1 to IS6.
– 12 – IEC 63044-6:2021 © IEC 2021
Figure 2 – Installation spaces
In 6.1.2, coexistence requirements between HBES/BACS cables and mains are specified.
If such requirements are met, the space for cable ways can be reduced accordingly.
An example of a building infrastructure is shown in Figure 3.
Figure 3 – Infrastructure for buildings
In Figure 3, the building in the foreground shows one single vertical backbone distribution, the
building in the background shows two vertical ways of distribution connected with each other.
The gateways to external services connecting the grounds with a public network may be in an
extra enclosure (IS1), which can be mandatory in certain cases, for example, IP network.
A maximum cable length between devices may be imposed for HBES/BACS functions.
Infrastructure planning shall consider such aspects for distances between installation spaces.
The general infrastructure may consist of the grounds, building, floors, flats, rooms, distribution
systems and shall be adapted to the needs by considering different types of buildings.
The infrastructure shall easily allow future extension/modification of the home/building network.
Figure 4 shows an example of a horizontal floor distribution infrastructure.
Horizontal floor distribution connects the floor installation space IS3 to the flat installation space
IS4.
Figure 4 – Horizontal infrastructure (floor distribution)
Figure 5 and Figure 6 show examples of the topology of installation spaces inside a home.
IS4 provides the space for equipment to distribute services in the home as well as home
gateway to the building network.
– 14 – IEC 63044-6:2021 © IEC 2021
IS5 is an intermediate space between IS4 and IS6 (terminal outlets).
Figure 5 – Example of infrastructure for ICT and BCT cabling for a flat
Figure 6 – Example of infrastructure for HBES network for a flat
Figure 7 shows an example of the physical allocation of the installation spaces IS6 and terminal
outlets inside a home.
Figure 7 – Example of allocation of installation spaces (IS5, IS6)
– 16 – IEC 63044-6:2021 © IEC 2021
NOTE Pathways connecting the installation spaces can be subjected to national regulations.
The height of the IS6 depends on the device to be installed. The following are suggested values:
– floor level: flood detectors;
– heights from the floor:
• power, TV and data sockets: 175 mm to 400 mm,
• junction boxes (IS5), LPG detectors: 300 mm,
• switches, pushbuttons, presence/movement sensors: 800 mm to 900 mm,
• panel boards, HD (IS4): 1 400 mm,
• intercom terminal displays: 1 600 mm,
• alarm commands (bathroom), bells, fans, cameras, loudspeakers, presence/movement
sensors: 2 250 mm;
– heights from the ceiling:
• sockets for kitchen fans: 100 mm to 200 mm,
• gas methane detector, emergency lamps: 400 mm;
– ceiling level:
• smoke detector,
• fans,
• loudspeakers,
• presence/movement sensors.
NOTE Installation heights to allow the use of equipment for special needs (e.g.to be accessed by disabled people)
can be different and are outside the scope of this document.
Additional recommendations by manufacturers should be considered.
In Figure 8, the heights for IS6 are shown.
Figure 8 – Indicative installation height for the most common HBES/BACS devices
Enclosures (IS1 to IS4) should be planned to allow fixing means to be mounted, for example to
allow 35 mm DIN rail (according to IEC 60715) to be mounted.
Flush mounting boxes according to IEC 60670-1 may be used to achieve IS6.
It is recommended to consider the infrastructures for a complete HBES/BACS at an early stage
of the building design. This allows the installation of the cables with minimum impact and allows
for future modifications and additions.
The pathway cross section shall be dimensioned to allow the installation of additional cables.
Consequently, the internal diameter of conduits between IS5 and IS6 shall be not less than
20 mm (or with an equivalent cross section for other shapes of conduits).
The cable ways shall be planned in order to guarantee the bending radius and the maximum
allowed pulling force of HBES cables.
6.1.2 Cohabitation of HBES/BACS and power cables
The cohabitation of HBES/BACS and power cables is subject to safety and EMC requirements
and recommendations.
Safety requirements are specified in IEC 60364-4-41.
– 18 – IEC 63044-6:2021 © IEC 2021
EMC requirements depend on the cable type, the application group (HBES/BACS, BCT, ICT)
and the maximum allowed parallel length (e.g. 90 m for ICT).
Table 1 shows the EMC requirements for the coexistence between HBES/BACS and power
cables for all the applications defined in IEC 63044-1. These requirements consider that all
devices of the HBES/BACS network comply with the immunity and emission requirements
specified in IEC 63044-5 (all parts) and/or the relevant product standards.

With reference to Table 1, cohabitation is:
– allowed if no significant impact of interference is expected.
– not allowed if interference is likely to create significant disturbance. Cohabitation may be
admitted for limited lengths (not longer than 2 m), if necessary for practical reasons.
6.1.3 Infrastructure requirements for outdoor wired HBES/BACS
If HBES/BACS are installed outdoors within the building premises, the following additional
requirements and recommendations apply:
– the underground pathways shall comply with IEC 61386-24;
– cables shall have an outdoor sheath;
– planning of underground cableways shall avoid collection of water and moisture; a minimum
slope should be foreseen as shown in Figure 9;
Figure 9 – Underground pathways
– the recommended depth of underground pathways is 0,5 m to 0,9 m (see also Figure 10);
– the planning of the pathways shall:
• respect the cable bending radii (see Figure 11 showing pathways from the building to
the outside). This radius depends on the type of cable. In the absence of information,
0,5 m is the recommended radius;
• include holes for access and maintenance. The length between the holes depends on
the maximum pulling strength of the cable (see Table 2);
• consider maximum distances covered by HBES/BACS;
– boxes shall be minimum IP55.

6.2 Infrastructure requirements for RF HBES/BACS
The planning of the infrastructure for RF HBES/BACS shall consider:
– positions of IS6 spaces to install devices;
– pathways to install power supply cables for RF devices;
– position of installation spaces dedicated to transmitting devices to ensure signal coverage
and to minimize any potential interference of and with other equipment and systems;
– maximum distances of radio links, considering the possible attenuation from obstacles.
The possible presence of an obstacle between the transmitter and the receiver may be difficult
to plan for, due to changes in furniture during the life of the home. For this reason, radio
connections shall be planned in such a way that they have enough margin of field strength at
the receiver side. Repeaters may be used to improve signal strength and coverage area.
Radio connections may also be affected by electromagnetic interferences.
EXAMPLES Interference sources in a home are
– computers and other ICT equipment,
– microwave ovens,
– electronic transformers,
– home theatre systems and television sets,
– controlgear for light sources.
HBES/BACS components may be supplied by power cable, batteries or energy harvesting (e.g.
piezoelectric) as shown in Figure 12.

8.2 Functional safety
Functional safety requirements for HBES/BACS devices are in accordance with IEC 63044-4.
9 EMC
The HBES/BACS devices shall comply with the requirements of IEC 63044-5 (all parts) and of
IEC 60364-4-44.
10 Earthing and bounding
Connection requirements for the screen of the bus cable (when present) shall comply with
IEC 60364-5-54.
Installation of HBES devices shall consider the different earthing systems:
– connected to a network which is installed wholly within the same equipotential earthing
system;
– connected to a network which is not installed wholly within the same equipotential earthing
system.
The HBES devices shall be selected accordingly.
11 Fire reaction and resistance requirements
No additional requirements to those given in IEC 60364-4-42.
12 Environmental aspects
Environmental aspects are under consideration.
13 Installation documentation
HBES/BACS should be installed based on technical documentation, with a unique reference
number allocated to each installation.
The technical documentation should be handed to the user of the installation and a copy of it
should be available for maintenance purposes.
This documentation may be provided electronically.
Under special circumstances, the user is allowed to modify the documentation themselves,
subject to national or local regulations.
Some guidelines are provided in Annex C.
Annex A
(informative)
Guidelines on HBES/BACS installation in existing buildings
Installation spaces described in 6.1 may not be present in existing buildings. In these cases,
installing HBES/BACS according to the guidelines given in this document should require
refurbishment of the building.
However, HBES/BACS may be installed at reasonable costs, according to the following
guidelines:
a) external boxes are easier to be placed than those that are flush mounted;
b) cohabitation rules reported in Table 1 allow sharing of conduits and therefore the saving of
installation space;
c) integration of a cabled network with wireless links may reduce size and total lengths of
conduits;
d) optical fibre systems may share infrastructures with non-electrical services;
e) manufacturer's installation guidelines may give additional suggestions on sharing
installation spaces.

(informative)
Installation guidelines for typical HBES/BACS applications
B.1 General
In the following subclauses, guidelines for the installation of specific applications are given.
B.2 Installation guidelines
B.2.1 Lighting and shutter control
An HBES/BACS lighting system is based on a logical connection between switches and
controlled actuating devices (actuators) physically connected by a cable or an RF link (see 6.2).
The logical connection between switches and actuators may be assigned via hardware, software
or a combination of both.
The actuators shall match the connected load: load type, power, etc. The manufacturer's
instructions should include information about the compatibility between the actuators and the
load.
The HBES/BACS lighting function may be activated through macro-commands releasing
combinations of lighting and shutter positions (scenes). Scenes may be programmed either in
sensors and/or in actuators or in specific memory devices according to manufacturer's
instructions.
B.2.2 Temperature control
Home temperature control may have the following implementations:
– central automatic control: one control unit with one sensor in a home;
– zone control (see Figure B.1): each zone has an independent control unit with a local
sensor.
