DESCRIPTION
The smoke extraction blade damper ERK-MB meets the require-
ments of EN 12101-8, EN 13501-4, EN 1366-2 and EN 1366-10.
The ERK-MB has been inspected according to EN 1366-2 and EN
1366-10 in accordance with the Declaration of Performance No.
DoP-ERK-MB-2019-04-01.
Depending on the installation situation, its classification accord-
ing to EN 13501-4:
EI 90 (v
edw
, h

i↔o) S 1000 C
10000
MA multi.
Smoke extraction blade dampers for multiple sections in
rectangular design are intended for extraction of smoke within
smoke extraction systems to smoke and heat control systems.
The smoke extraction blade dampers are driven by a reversible
OPEN/CLOSE actuator with 24 V AC/DC or 230 V AC supply vol-
tage. It is located in a thermally insulated actuator housing to
ensure correct opening and closing of the smoke extraction
blade damper under fire conditions.
Optionally, the ERK-MB can be equipped with the EK12 (SEL
1.90 SLC, 24 V AC/DC) / EK14 (EK12 + SPMa-1SR) actuator. Each
smoke extraction blade damper is connected only with one
two-wire line by means of the SLC technology, detecting and re-
porting short-circuit or line break of the SLC lines by constant
monitoring. The function of the actuator EK12 is only active
when an additional required communication device (e.g. EK14 =
EK12 + SPMa-1SR) is connected.
Suitable communication devices (e.g. SPMa1SR or SPLM-4S 0SD
Mod) allow retrieving data, such as indication of end position,
keeping timeframe (<60 s) or torque monitoring.
For installation in solid walls and in dry building walls for supp-
lying air or extraction of smoke, also in combination with smoke
extraction ducts in compliance with EN 121017 which have been
inspected according to EN 13668 or EN 13669.
The national standards and guidelines must be observed in
connection with this technical documentation, installation,
mounting and operating instructions.
For functional test, service, retrofitting, etc., inspection ope-
nings must be provided on site in suspended ceilings, shaft
walls, connected ventilation ducts etc., if necessary. They must
be built in sufficient numbers and size and must not impair the
functioning of the smoke extraction blade dampers.
Housing and blade dampers made of silicate structural panel,
optionally (at an extra charge):
•
SR impregnation for protection against aggressive me-
dia:
Inside (BS 06-1)
Outside (BS 06-2)
inside and outside (BS 06-3)
•
Impregnation 2000 for hydrophobization (protection
against humidity):
Inside (BS 06-4)
Outside (BS 06-5)
inside and outside (BS 06-6)
•
Colour coating (dispersion/alkyd resin-based paint) RAL
colour must be specified when ordering:
Inside (BS 06-7, 07-xxxx)
Outside (BS 06-8, 07-xxxx)
inside and outside (BS 06-9,07-xxxx)
With stop bar seals to meet the cold and hot leakage require-
ments.
As standard, the security grille ASG-E is mounted on the opera-
ting side BS.
Horizontal or vertical position of the blade damper axles (depen-
ding on the installation situation).
The installation position does not depend on the air flow direc-
tion.
The actuator can be positioned on the right, on the left, at the
top or at the bottom.
The maximum inflow velocity v
stirn
is
≤ 10 m/s (with maximum dimensions).
The connection to smoke extraction ducts made of wall boards is
done according to inspected duct-specific constructions. Smoke
extraction systems with mechanical vents require a secure power
supply in case of fire. A power supply above the public supply,
through a power producing installation (replacement power) de-
pends on each case of public and legal requirements.
ATTENTION
Building systems have to be arranged, installed and maintained
in such a way that they prevent fire and propagation of fire and
smoke (fire propagation) and allow evacuation of persons and
animals as well as efficient fire extinguishing work.
