DESCRIPTION
Fire dampers, installed in ventilation ducts (air conditioning
systems), serve for the automatic locking of fire lobbies. The
fire damper BKA-EN conforms to EN 15650, EN 13501-3 and
EN 1366-2. The BKA-EN has been tested according to EN
1366-2 in compliance with Declaration of Performance No.
DoP-BKA-EN-2020-07-10. Its classification according to EN
13501-3 is EI 30 (v
e
, i↔o) S to EI 90 (v

o
i↔o) S.
According to Directive 2014/34/EU, EC Certificate of Conform-
ity Number EPS 09 ATEX 2 153 X, its use in areas subject to
explosion hazards is permitted, not only with spring return ac-
tuator ExMax-5.10-BF (X14/X15), including safety tempera-
ture limiter (ExPro-TT), but also with mechanical release via
fusible link (manual actuation with or without ATEX limit
switch ES-Ex). The fire damper is marked as follows according
to ATEX:

EPS 09 ATEX 2 153 X
II 2 D Ex h IIIC T80°C Db
The national standards and guidelines must be observed in
connection with these additional operating instructions.
For functional test, service, retrofitting, etc., inspection open-
ings must be provided on site in suspended ceilings, shaft
walls, connected ventilation ducts etc., if necessary. They
must be built in in sufficient numbers and sizes and must not
impair the functioning of the fire dampers.
The fire dampers must be connected to the ventilation system
by means of ventilation ducts either on one or on both sides.
When connected on one side, security grille made of non-
flammable building materials (EN13501-1) must be provided
on the opposite side. The fire dampers can be connected to
non-flammable and flammable ventilation ducts as well as to
flexible spigots.
The fire damper complies with the regulations of the ATEX di-
rectives and may be used in supply and return air installations
of ventilation systems in areas subject to explosion hazards.
The fire damper is certified for device group II, Zones 1, 2 and
21, 22.
Zones 1 and 2 represent the application range containing
gases/vapours, while Zones 21 and 22 represent the applica-
tion range containing dusts.
Classification by zone must be established by the system op-
erator or planner in compliance with current standards.
Note:
In explosion-protected zones, only devices that have an ATEX
approval for this use may be used.
SPECIAL CONDITIONS
The attached and installed electrical devices must have a suit-
able explosion-proof design.
It must be ensured that all metal components are properly
and permanently connected to the ground potential.
TYPE OF IGNITION PROTECTION
The type of ignition protection of the fire dampers is guaran-
teed by their safe design.
QUALITY ASSURANCE
The SCHAKO production facilities are certified according to
the QM procedure EN ISO 9001.
To ensure that the defined product features are adhered to
during the production, a factory production control is carried
out at regular intervals. In addition, a notified body carries
out an external audit once a year.
