Important Regulations
Observe regulations for danger warning systems VDE 0833, guidelines for electrical systems VdS 2221, VDE 0100,
DIN 18232 for smoke and heat vent systems, regulations of the local fire-brigade and of EVU for connection to mains
supply.
Introduction
Smoke and heat vent systems (RWA´s) are very important elements of structural
preventive fire protection.
Smoke and heat vent systems are appliances of preventive fire protection. They fulfil important functions in case of
fire: protection of human life by providing a smokeless layer, by which rescue routes are kept free for the fire-
brigade. Consequential damages by conflagration gases are reduced, and therefore, considerable material assets are
often protected from destruction. Precondition for this is, that the systems will function absolutely reliable in a case
of fire. Only electrical specialist companies are authorized to install these systems, who have electrical specialist
staff with relevant experiences in installing danger alarm systems or smoke and heat vent systems. Only these ones
can take on responsibility for functioning, and can ensure product liability for the whole system (see product liability
law BGBL.I S.2198 and BGB (bodily injury, compensation for damage)).
Therefore, regular maintenance and checking of functional readiness is imperative and has to be ensured. These
standard requirements are demanded according to regulations of the DIN, of the Association of German Insurer
against damage of property (VdS) and the respective local authorities. Recommended is, that maintenance work
should be carried out by authorized specialist companies, only.
Only regular and professional maintenance warrants the necessary and permanent
functional safety.
Only authorized specialist companies are allowed to install and maintain smoke and heat vent systems and system
components, constructed and distributed by
D+H Mechatronic AG
. All
D+H Mechatronic AG
partners belong to these
authorized specialist companies, who regularly undergo an in-house training to ensure their qualification and experience.
Smoke and heat vent systems must be maintained at annual intervals by authorized specialist companies according
to DIN 18232 section 2 paragraph 10.2, and VDE 0833 section 1 paragraph 5.3.4 for alarm systems and manufacturer
guidelines.
According to DIN VDE 0108 section 1 paragraph 9.1.1 accumulators for emergency supply (lead accumulators) must
be checked every six months by a person, who has been introduced to this task, and once a year, maintenance must
be carried out by specialist companies. Accumulator types, which are used for
D+H Mechatronic AG
smoke and heat
vent systems must be VdS approved, and must be released by
D+H Mechatronic AG
to use in smoke and heat vent
systems. According to DIN 18232 section 2 paragraph 10.2 the tests must be put down in an operational book, which
the operator/ building owner must present to the building supervision authority on request. This operational book is
available at D+H (Ord.-No.: 68.700.15)
Executed maintenance must be proved by a
D+H Mechatronic AG
maintenance/ and testing confirmation.
