“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

and can thus be used easily.

BSS 167



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.

BSS168



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

Summary:

Here, the installation engineer

can “play it sae”.
