“Function maintenance” means the guarantee o the power supply to saety-relevant installations,
such as emergency lighting and smoke extractors, in the event o re.
OBO oers a broad range o practical systems or electrical installations or unction maintenance or almost
every eld o application and mounting type. All the OBO systems are tested according to DIN 4102 Part 12

3rd protection aim:
Important electrical systems must continue to unction.
Solution: unction maintenance or electrical systems
To ensure that emergency and es-cape routes remain usable and also
important technical equipment such
as emergency lighting, re alarm sys-
tems, smoke exhaust systems, etc.
in case o re, it is absolutely essen-tial to provide special protection or
the power supply or these systems.
The use o special cables and rout-
ing systems means that it is possible
to maintain the power supply, evenin the case o re, thus guaranteeing
the unction maintenance.
What is a cable system with
integrated unction maintenance?
A cable system with integrated unc-
tion maintenance is, according to
DIN 4102 Part 12, the combination o
the routing system (cable ladder,
cable tray, etc.) and cables with inte-grated unction maintenance.
Cables and standard routing
systems
The standard species that unction
maintenance o an electrical cable
system includes not just the cables
themselves, but also the routing sys-
tems. DIN 4102 Part 12 denes threestandard routing systems:
Routing on cable ladders Routing on cable trays Individual cable routing under
the ceiling
All the OBO routing system or elec-
trical installations with unction main-
tenance correspond to DIN 4102
Part 12.
Function maintenance
in the building regulations
The requirement or electrical instal-
lations with unction maintenance is
a component part o the building
regulations o the German ederal
states. This type o installation isparticularly required or buildings in
which many people meet regularly:
public buildings, hotels, meeting
places, large industrial complexes,
etc. Function maintenance applies
solely to those areas which provide
the power supply to saety-relevant
systems such as emergency light-
ing, alarm systems, re alarm sys-
tems, smoke extraction systems, etc.
Here, the regulations require the
power supply to be guaranteed or a
specic period o time, even i there
is a re.

System labelling by the
installation engineer
Each cable system must be perman-
ently labelled with a sign. This label-
ling must contain the ollowing inor-
mation:
Name o the erection engineer o
the cable system (installation en-
gineer) Function maintenance class E... Test certicate number
Owner o the test certicate Year o manuacture
BSS 169
Besides the type and quantity o
cables, the selection o the cor-
rect system is dependent on the
actual conditions on the con-
struction site.
Fastening systems
O equal importance to the selection
o the support system is the decision
or the most suitable astening sys-
tem. Here, too, the individual actors
on the construction site must be
taken into account. The Fastening
systems section contains proes-
sional, easy-to-mount solutions or
any requirements.
Space with multiple girders
Please note that, i there are jumps in
height, the installed cables must be
supported. This may be required,
when cables with large cross-sec-
tions are not supported by the sup-
port system.
Combination
with other systems
Ventilation systems, pipes, etc. may
not be mounted above the electrical
installation with unction mainten-
ance, as, i there is a re, parts may
all down, damaging the unction
maintenance cables. The solution is to
employ cable mounting with clips
directly under the ceiling or on the wall.
Restricted spaces
The solution here is either cable
mounting with clips or pressure clips
directly under the ceiling or the
installation o multiple narrow cabletracks above each other instead o
one wide track.
Problematic substrate
As, or old ceiling structures, e.g. dur-
ing renovation projects, the support
orce cannot be ocially claried, we
recommend wall mounting.

Fire testing
The proo o the unction mainten-
ance property o electrical installa-
tion material must be provided by
re testing to DIN 4102 Part 12 in an
independent materials testing oce.
The test is carried out in a special
testing urnace in which the installa-
tion to be tested is heated up ac-
cording to a standard temperature-
time curve. The cable systems areawarded the classes E30 to E90,
depending on the length or which
they manage to survive.
Proos and approvals
The result o the re test is docu-
mented in a construction testing
certicate. This test certicate is valid
or cable systems with
cable-specic support
structures as a proo
o unction maintenance. With standard support struc-
tures, the proo o unction
maintenance also requiressurveyor’s comments in addition
to the testing certicate.

Extreme loads or
cables
I there is a re, the cables are sub- jected to extreme loads rom fames
and heat. Nevertheless, cables used
or a unction maintenance installa-
tion must be able to withstand tem-
peratures o 1,000 °C and more or a
certain period o time, without there
being a short-circuit o the copper
conductor. As the copper conductor
may anneal at these extreme tem-
peratures, thus impairing its own
mechanical stability, the support
system serving as a “support cor-
set” has a special signicance.
Cables with integrated unction
maintenance
Thereore, in the case o cables with
integrated unction maintenance, the
insulation has a special role to play.
These cables possess a special
winding around the copper conduct-
or made o glass silk or mica tape. I
there is a re, then the cable insula-tion burns completely, creating a
layer o ash. This is kept together by
the windings and ensures that the
copper conductors are kept apart
and that no short-circuit o the sup-
port system can take place. In add-
ition, a new product on the market is
a cable, which, instead o special
windings, has a ceramising plastic
insulation. I there is a re, this spe-
cial plastic orms a ceramising ash,
which also produces the required in-
sulation o the current-carrying cores.
Halogen-ree plastic
Cables with integrated unction main-
tenance are always made o halogen-
ree plastic. These materials, which do
not contain any chlorine, bromine or
fuorine, do not create any corrosive
re gases during combustion.
Low smoke and reducedfre spread
In addition, cables with integrated
unction maintenance have addition-
al positive properties during a re,
or example:
Low smoke and/or Reduced re spread

Selection aid, unction maintenance systems
Standard support structureWith standard support structures, it
is possible to select reely the cables
required or the installation. This is
possible, as all the cable manuac-
turers have proven the unction main-
tenance o their cables or the stand-
ard support systems.
Benefts Free choice o cables, as the
combination o cables and the
standard support structure has
the unction maintenance proo Not bound to one specic
cable type This structure is ideal or smaller
projects Testing means that the countless
installation variants are approved
or many years

Here, the installation engineer
can “play it sae”.
