DESCRIPTION
The smoke extraction damper ERK-SO conforms to EN 12101-
8, EN 13501-4, EN 1366-2 and EN 1366-10. The ERK-SO has
been tested according to EN 1366-2 and EN 1366-10 in ac-
cordance with the Declaration of Performance No. DoP-ERK-
SO-2016-07-01. It is in possession of the Performance Relia-
bility Certificate according to EU-BauPVO 0761 - CPR - 0506.
Its classification according to EN 13501-4, depending on the
mounting situation is:
EI 90 (v

Smoke extraction dampers are intended for ventilating smoke
in smoke extraction systems and for providing necessary sup-
ply air within the smoke extraction installation.
The smoke extraction dampers are driven by a reversible
OPEN / CLOSE actuator with 24 V AC/DC or 230 V AC supply
voltage. It is located in a thermally insulated actuator housing
to ensure correct opening and closing of the smoke extrac-
tion damper under fire conditions.
Optionally, the ERK-SO can be equipped with the EK12 (SEL
1.90 SLC, 24 V AC/DC) / EK14 (EK12 + SPMa-1SR) actuator.
Each smoke extraction damper is connected only with one
two-wire line by means of the SLC technology, thus allowing
detection or reporting of short-circuit or line break of the SLC
lines through constant monitoring. The function of the actua-
tor EK12 is only active when an additional required communi-
cation device (e.g. EK14 = EK12 + SPMa-1SR) is connected.
Suitable communication devices, for example SPMa1SR or
SPLM-4S 0SD Mod. allow retrieving data, such as indication of
end position, keeping timeframe (<60 s) or torque monitor-
ing.
For use in solid walls and ceilings for supplying air or ventilat-
ing smoke, also in combination with smoke extraction lines in
compliance with EN 121017 which have been tested accord-
ing 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 open-
ings 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 im-
pair the functioning of the smoke extraction dampers.
o
Housing and damper blade made of silicate struc-
tural panel,
optionally (at an extra charge):
•
SR internal impregnation (ex works only) for
protection against aggressive media
o
With circumferential stop bar seals to meet the cold
and hot leakage requirements
o
Horizontal or vertical position of the damper blade
axle (axle made of stainless steel)
o
The installation position does not depend on the air
flow direction

The connection to smoke extraction ducts made of
wall boards is done according to inspected duct-spe-
cific constructions. The connection to the tested
sheet steel lines or flexible spigots is carried out via
the profile connection frame type PAR. Smoke ex-
traction systems with mechanical vents require a se-
cure power supply in case of fire. A power supply
above the public supply, through a power producing
installation (replacement power) depends on each
case of public and legal requirements.
ATTENTION
Building systems have to be arranged, installed and main-
tained 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.
