DESCRIPTION

Smoke extraction damper ERK-SO

TECHNICAL DOCUMENTATION

Description |

The smoke extraction damper ERK-SO conforms to EN 12101­8, 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 ac­cordance with the Declaration of Performance No. DoP-ERK­SO-2016-07-01. It is in possession of the Performance Relia­bility 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 sup­ply 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 extrac­tion 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 actua­tor EK12 is only active when an additional required communi­cation device (e.g. EK14 = EK12 + SPMa-1SR) is connected.

, how i↔o) S 1000 C

edw

MA multi.

For functional test, service, retrofitting, etc., inspection open­ings 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 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

o The connection to smoke extraction ducts made of

wall boards is done according to inspected duct-spe­cific constructions. The connection to the tested
sheet steel lines or flexible spigots is carried out via
the profile connection frame type PAR. 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) depends on each
case of public and legal requirements.

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 monitor­ing.

For use in solid walls and ceilings for supplying air or ventilat­ing smoke, also in combination with smoke extraction lines in
compliance with EN 121017 which have been tested 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.

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.

Table 3 - Usability

General information

o During mounting or installation, there is a risk of in-

juries. To avoid injuries, personal protective equip­ment (PPE) must be worn.

o Smoke extraction dampers must be installed such

that external forces do not impair their functioning.
During mounting it may be required to provide rein­forcements for the housing or the like. The require­ment of statically load-bearing lintels may have to be
taken into consideration.

o Improper transport/handling may result in dam-

age/functional impairment. In addition to that, the
film of the transport packaging must be removed
and the delivery inspected for completeness.

o In storage, smoke extraction dampers must be pro-

tected from dust, dirt, moisture and the effects of
extreme temperatures. They must not be exposed to
direct effects of the weather.

4)

5)

in connection with on-site suspensions

6)

in connection with on-site fastening frames and suspen-

sions

o The smoke extraction dampers must be protected

from dirt and damage. After installation is complete,
any dirt must be removed immediately.

o Enough space must be provided for installation, mor-

tar lining, etc.

o Carry out a functional check of the smoke extraction

damper before and after mounting and ensure ready
access.

o Electrical installations or work on electrical compo-

nents may only be carried out by skilled electricians.
The supply voltage must be switched off when per­forming this work.

o Always check whether the housing needs to be ex-

tended on the b side (MS) for the corresponding in­stallation situations (e.g. the thickness of the sup­porting structure and a possible connection to the
smoke extraction duct must be considered).

the construction of the ceiling, the gaps "s" can be
omitted. The mortar bed depth must be executed in
the minimum ceiling thickness and may not be less
than 150 mm. When performing a mortar lining or
direct installation, make sure that the housing is not
pressed toward the inside (reinforcement).
For load carrying when installed in solid ceilings (ver­tical/suspended), additional mounting brackets WE-S
are required.

the calculated tension of 6 N/mm² is not exceeded (this ap­plies to a max. length of 1.5 m). The max. extension when ex­posed to temperature according to ETK (approx. 1000 °C) for
90 min. with regard to threaded rods with a length of 1.5 m is
40 mm. Due to larger extension, suspensions with a length of
more than

1.5 m must be covered to provide safe fire protection.

Mounting instructions

The suspension coverings consist of a pipe made of sheet
steel with internal fireproof lining.

In the centre of it, there is an at least 21 mm large bore for
mounting the threaded rod. Starting form suspension M14,
the connection sleeve for two threaded rods cannot be lo­cated in the area of the suspension covering any more, there­fore a connection sleeve covering as shown opposite must be
mounted.

Minimum distances and projecting ends |

TECHNICAL DOCUMENTATION

MINIMUM DISTANCES AND PROJECTING
ENDS

The dimensions given must be considered an installation rec­ommendation for the ERK-SO and may differ, depending on
the local situation. The smoke extraction damper must be in­stalled in accordance with the technical documentation, in­stallation, mounting and operating instructions.
For functional test, service, retrofitting, etc., inspection open­ings 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 dampers; they
may lead to increasing the distances.

Ceiling

Wall

Figure 23: Minimum distances to walls and ceilings and ERK-SO to one another

1) The distance between smoke extraction damper and load­carrying component (wall/ceiling) must be determined ac­cording to the particular installation situation or adjusted
to the dimensions of the projecting ends (actuator hous­ing) and is at least 75 mm.

2) The distance between two smoke extraction dampers de­pends on the particular installation situation and is de­scribed in the corresponding installation situations. (p. 7
and the following pages).

SERVICE

CHECKING THE FUNCTION, CLEANING, REPAIR

Installation information

The assembly must be made in a way that the inner viewing,
cleaning and maintenance of the smoke damper is possible. To
this end, suitable inspection openings must be provided in the
connected smoke extraction ducts, if required. The connection
to smoke extraction ducts made of wall boards is done accord­ing to inspected duct-specific constructions. The connection to
inspected sheet steel ducts or flexible connection pieces is
done via the profiled mounting frame type PAR.

Regulations for use and maintenance

- The operator of the smoke extraction installation must en­sure that smoke extraction dampers are always kept in a
ready-to-operate state and are maintained.

- Smoke extraction dampers must undergo maintenance at a
six-month interval. If two consecutive inspections do not
show any malfunctions, the maintenance interval of the
smoke extraction dampers can be reduced to once a year.

- An inspection report must be produced, and the documents
must be kept by the operator of the smoke extraction instal­lation.

o The smoke extraction dampers must be installed in ac-

cordance with the technical documentation, installa­tion, mounting and operating instructions.

o The work must be carried out by specialised compa-

nies only.

o Observe general accident prevention regulations.
o The smoke extraction dampers must be installed such

that they are accessible.

o For internal inspection and cleaning of the smoke ex-

traction dampers, install inspection openings in the
continuation connection lines.

o The cover of the temperature-resistant actuator hous-

ing can be dismounted for electrical wiring and must
be properly remounted (screwed) once the wiring is
completed; the actuator itself is maintenance-free.

o The electrical line installation must be at least E30, ac-

cording to DIN 4102-12.

e.g. SPLM-4S 0SD Mod / SPMa-1SR (component of
EK14).

o From the switch cabinet, give pulse for open position

(smoke extraction) or closed position (fire).

o Damper blade moves to open/closed position; the

movement is controlled by motor.

Limit switches integrated in the actuator indicate the

o

open/closed positions.
