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 special-
ist 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.
