DESCRIPTION
Fire dampers, installed in ventilation ducts (air conditioning
systems), serve for the automatic locking of fire lobbies.
The fire damper BSK-RPR-EU corresponds to EN 15650, EN
13501-3 and EN 1366-2.
The BSK-RPR-EU has been tested according to EN 1366-2 in com-
pliance with Declaration of Performance no. DoP-BSK-RPR-EU-
2017-08-09. Its classification according to EN 13501-3 is EI 120
(vei  o) S.
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 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, finishing protective gratings
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.
Housing made of galvanised sheet steel (standard), option-
ally (at an extra charge):
Housing made of stainless steel material no. 1.4301
or material no. 1.4571
Housing with DD coating (two-component top coat
based on polyurethane varnish) inside / outside
Model with plug-in connection (-S) or flanged connection
(-F) according to EN 12220 and DIN 24154-1, respectively.
Damper leaf made of silicate board,
optionally (at an extra charge):
DD coating (RAL 7035 / light-grey)
Cold and hot leakage requirements according to EN 1366-
2 are complied with using circumferential rubber and intu-
mescent seals.
Horizontal position of the damper blade axle
The installation position is independent of the air flow di-
rection.
Thermal trigger via fusible link 72°C;
optionally (at an extra charge)
equipped with electrical release devices
Use: max. operating pressure of 1000 Pa at vface ≤ 10 m/s
Housing leakage class C according to EN 1751
Use or connection of a smoke trigger device with general
building supervisory approval (e.g. SCHAKO smoke detection
system RMS, see technical documentation smoke detection
system RMS) in connection with suitable electric release de-
vices of the fire damper is possible; only release devices
working by the "currentless closed" principle may be con-
nected to the RMS system; the propagation of fire and
smoke is effectively prevented. Optimal integration into the
building control system by means of the SCHAKO EasyBus
signalling and switching bus system (see technical documen-
tation EasyBus) or the SCHAKO fire damper mini-controller
BKSYS (see technical documentation BKSYS).
ATTENTION
Building systems have to be arranged, installed, changed and
maintained in such a way that they prevent fire and propaga-
tion of fire and smoke (fire propagation) and allow evacuation
of people and animals as well as efficient fire extinguishing
work.
Smoke propagation through the air-conditioning and ventila-
tion system can be prevented for example by means of fire
dampers and spring return actuators in combination with ap-
proved smoke detector devices (e.g. SCHAKO smoke detection
system RMS).
GENERAL
Data and requirements according to German standards (DIN)
must be checked on site for compatibility with current stand-
ards and directives in the respective states/countries and
adapted, if necessary. Whether the installation of flexible con-
nection pieces is required, must be determined on site.

General information
 During mounting or installation, there is a risk of injuries. To
avoid any possible injuries, personal protective equipment
(PPE) must be worn.
 Fire dampers must be installed such that external forces do not
impair their permanent functioning.
 Ventilation ducts must not exert significant forces on walls,
supports or ceilings and thus also on fire dampers as a result
of thermal expansion (in case of fire).
Appropriate compensation measures, such as the arrange-
ment of flexible spigots or a suitable duct routing (duct angles
and distortions), must be taken as required. National regula-
tions must be observed and adhered to.
 Prior to installing the fire damper, the possibility to connect
the ventilation ducts must be checked. Extension pieces (on
site or as accessories SCHAKO type VT-RF) might be neces-
sary, e.g. for large wall and ceiling thicknesses. When con-
necting duct components, a fastening type must be selected
that causes no damage to the fire damper or its accessories.
 During mounting it may be required to provide reinforce-
ments for the housing or the like.
 The requirement of statically load-bearing lintels may have to
be taken into consideration.
 Improper transport/handling may result in damage/functional
impairment. In addition to that, the film of the transport
packaging must be removed and the delivery inspected for
completeness.
 During storage, fire dampers must be protected from dust,
dirt, moisture and the effects of temperature (e.g. direct sun-
light, heat-emitting light source, etc.). They must not be ex-
posed to direct effects of the weather and must not be stored
below -20 °C or above 50 °C.
 The fire damper must be protected from dirt and damage. Af-
ter installation is complete, any dirt must be removed imme-
diately.
 Enough space must be provided for installation, mortar lining,
etc.
 Carry out a functional check of the fire damper before and af-
ter mounting and ensure ready access.
 Electrical installation or work on electrical components may
only be carried out by skilled electricians. The supply voltage
must be switched off when performing this work and secured
against being switched on again.
 We would like to point out that only suitable cleaning materi-
als may be used to clean the stainless steel version of fire
dampers!
Minimum distances or projecting ends
The dimensions given must be considered an installation rec-
ommendation for the BSK-RPR-EU and may differ, depending
on the local situation. To guarantee fire protection, the fire
damper must be installed in accordance with the technical
documentation, installation, mounting and operating instruc-
tions.
There are no inspection openings on the BSK-RPR-EU, which is
why inspection openings in the connected ventilation ducts
must be provided in the immediate proximity. Inspection
openings must be freely accessible, which must be ensured in
particular when at least 2 fire dampers are installed next to
each other or below each other in the immediate proximity of
adjacent components.

Installation in solid walls
Construction subject to change
No return possible Version: 2021-07-01 | Page 8
Wet installation (mortar lining)
 The fire damper is installed by means of mortar lining. It
must be completely filled with mortar of class M 10 to M
15 according to EN 998-2 or fire protection mortar of cor-
responding grades or with concrete or plaster mortar
suitable for the wall or ceiling type.
 If the fire damper is installed during the assembly of the
wall, the annular gap dimensions can be smaller than
specified.
 The mortar bed depth must be designed according to the
minimum wall thickness and may not be less than this
thickness.
 The mortar lining must be executed such that it is perma-
nent. The information given by the mortar manufacturer
must be observed.
INSTALLATION IN SOLID WALLS
Installation in solid walls (shaft walls, shafts, ducts and fire
walls) made of, for example, concrete; masonry according
to EN 1996 or DIN 1053; solid plaster wall boards according
to EN 12859; apparent density ≥ 450 kg/m³ and wall thick-
ness W ≥150 mm.

INSTALLATION INFORMATION
Connection of ventilation ducts
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, finishing protective gratings
made of non-flammable building materials (EN13501-1) must
be provided on the opposite side. The fire dampers can be con-
nected to non-flammable as well as flammable ventilation
ducts. Ventilation ducts must be suspended separately.
The local regulations or national standards on ventilation sys-
tems (in Germany e.g. LüAR) apply. It is important that ventila-
tion ducts do not exert significant forces on walls, supports or
ceilings and thus also on fire dampers as a result of thermal
expansion (in case of fire). Appropriate compensation
measures, such as the arrangement of flexible spigots or a suit-
able duct routing (duct angles and distortions), must be taken
as required. National regulations must be observed and ad-
hered to.

tions and unlocked mechanically.
Electric spring return actuator with thermoelectric release de-
vice BAT.
Release temperatures: ambient temperature 72 °C and in-
ternal duct temperature 72 °C.
Operating position (damper "OPEN") and tensioning of the
return spring by applying the supply voltage.
24V actuators with connectors that can be removed on site
if required.
Safety position (damper "CLOSED") through spring force
when supply voltage is interrupted or the temperature
fuses (ambient temperature: 72°C or internal duct temper-
ature: 72°C) respond. Reaction of the thermal fuses inter-
rupts the supply voltage permanently.
Indication of damper end positions by integrated micro-
switches via potential-free changeover contacts (S1 - S3
"CLOSED" indicates "CLOSED" position; S4 - S6 "OPEN" in-
dicates "OPEN" position).
Manual actuation and fixing in any position is possible in
the de-energised state. It is unlocked manually.
On-site function control is possible by means of the control
key of BAT.
Spare parts: Temperature fuse for internal duct tempera-
ture (ZBAT72).
Replacement takes place by unscrewing both screws at the
thermoelectric release device. Remove the thermoelectric
release device from the actuator unit. Remove the internal
duct temperature fuse from the thermoelectric release de-
vice and replace it with a new internal duct temperature
fuse (ZBAT72). Screw the thermo-electrical release device
back onto the actuator unit.
For any other damage etc., the entire "actuator/thermal
release device" must be replaced completely.
