Frankfurt a. M. / Schalksmühle. Constructional fire protection is one
of the most important factors in building practice. The aim of
preventive fire protection is to prevent the occurrence and spreading
of smoke and fire in order to save lives and minimise property
damage. The relevant standards and sets of regulations affect not
only new building but also refurbishing in existing buildings.
Electrical installations are a potential weak spot if, for example,
missing or incorrectly fitted sealings for electrical cables and conduits
allow smoke and fire to spread. With regard to fire resistance classes
according to DIN 4102 or EN 1364, fire-protection walls represent
especially complex challenges for the electrical trade. In this case,
electrical installations must be carried out with extra care in order to
ensure fire and smoke safety. Not only in new buildings, but also for
the
modernising
of
existing
buildings,
practice-oriented
and
economical measures are needed in order to satisfy the fire
protection requirements and at the same time to minimise the amount
of work involved.

As specialists in electrical installations in fire-protection walls and
ceilings, at the "Light+Building 2012" trade fair KAISER GmbH & Co.
KAISER GmbH & Co. KG
Ramsloh 4
D-58579 Schalksmühle
KG presented innovative and reliable systems which ensure the
necessary fire resistance classes if a fire breaks out. With a new
product for the trade fair, KAISER has added a 120 mm diameter box
sealing to its product range of feed-throughs in cavity walls, masonry
and concrete. The "System DS 90 / 120 mm“ covers an expanded
range of applications in fire protection. It is based on the innovative
technology used for the "DS 90" box sealing system, which has
Europe-wide approval. The increased diameter allows the fitter to
feed through a larger number of cables and electrical installation
conduits, and also larger cross-sections. In addition, the new system
allows mixed population of conduits and cables as full population.
With European Technical Approval, issued in autumn 2011 by the
German Institute of Building Technology for sealing systems "LS 90",
"RS 90" and "DS 90/74 mm", professional use for electrical
installations in fire-protection walls is officially confirmed. The
approval (ETA-11/0188) was issued on the basis of the fire tests
passed in accordance with DIN EN 1366-3. This means that these
sealings can be used in solid masonry walls according to DIN 1053,
in concrete walls according to DIN 1045, and in drywalls according to
DIN EN 1364-1. The ETA approval can be downloaded from our
website at www.kaiser-elektro.de.
KAISER's fire sealings allow fast, flexible and secure sealing,
maintain the wall's fire resistance class, and automatically seal joints
and gaps between cables. They give the electrical trade professional
products which allow fire-protection-safe electrical installation using
existing tools and without filling and smoothing or even the application
of a fire-protection coating to cables and conduits. The cable, conduit
and box sealings can also be retrofitted over existing cables and
conduits. In each case, up to three sealings can be arranged as a
group.
An additional special feature of KAISER's box sealings is the
possibility of the later non-destructive fitting of additional cables in all
wall types. For later non-destructive fitting, first open the sealing
element, and additional cables can then be fed through. After this, the

Electronics box with a wide range of applications
info@kaiser-elektro.de
www.kaiser-elektro.de
The "Electronics box HWD 90“ is another new product for F30 to F90
fire-protection walls. It maintains the fire-resistance class and creates
additional installation space for electronic switch devices, network
and communications technology, and also cables and terminals. It
allows population with up to 4 cables and also with a maximum of four
installation conduits up to M25. An additional space for electronic
components such as KNX actuators, relays, radio modules and
communication technology products creates a wide range of
applications. The new electronics box is based on the tried-andtested "HWD 90“ cavity wall box. It is also suitable for later installation
and, if required, can also be used as a double box.
All fire sealings and fire-protection boxes are equipped with so-called
"AFS technology“. "AFS“ stands for "Active Fire Stop“, and it
designates a surrounding fire-retardant coating which intumesces
extremely quickly if a fire breaks out and automatically closes the
installation openings. This technology ensures that fire-resistance
classes up to EI90 or F90 are maintained, which reliably prevents the
spreading of smoke and fire.
It is also easy to replace existing traditional installation boxes, or to
expand existing installation boxes to create multiple combinations.
KAISER has developed the "Centering insert 68/74“ for this purpose,
and it easily and quickly expands the installation openings from 68
mm to 74 mm without damaging the surface of the wall. The robust
centering insert is especially designed for installation work in single
and multi-layer boarded lightweight walls.
