DESCRIPTION
Fire dampers built into ventilation ducts (air-conditioning sys-
tems) are used for the automatic locking of fire lobbies.
The fire damper BKP-EN conforms to EN 15650, EN 13501-3
and EN 1366-2.
The BKP-EN has been tested according to EN 1366-2 in com-
pliance with Declaration of Performance No. DoP-BKP-EN-
2020-09-01. Its classification according to EN 13501-3 is EI 90
(ve, ho i↔o) S to EI 120 (ve, ho i↔o) S.
According to Directive 2014/34/EU, EC Certificate of Conform-
ity Number EPS 13 ATEX 2 610 X, its use in areas subject to
explosion hazards is permitted, not only with spring return ac-
tuator ExMax-5.10-BF (X10 - X15), including safety tempera-
ture limiter (FireSafe or ExPro-TT), but also with mechanical
trigger via fusible link (manual actuation with
or without ATEX limit switch ES-Ex). The fire damper is marked
as follows according to ATEX:
*) when using the safety temperature limiter FireSafe.
The national standards and guidelines must be observed in
connection with this technical documentation "Installation,
mounting and operating instructions". Further information on
ATEX can be found in the additional BKP-EN operating instruc-
tions according to ATEX 2014/34/EU.
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.
optionally (at an extra charge):
 Housing made of stainless steel material no. 1.4301
 Housing with DD coating (two-component
top coat based on polyurethane varnish) inside/out-
side (replaceable, non-coated parts are made of
stainless steel material no. 1.4301)
 Moulded connection flanges with centre hole or three
equidistant holes on the B side (from B ≥ 200 mm), corner
angle with long hole for simple duct mounting and high
stability
 Shut-off damper 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 met by means of circumferential rubber
and intumescent 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 or 98 °C
optionally (at an extra charge):
 with electrothermal trigger devices (with spring re-
turn actuators)
 with an inspection opening on the B side (bottom), from
B ≥ 200 mm.
 Use: max. operating pressure of 1000 Pa at vstirn ≤ 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 detec-
tion system RMS, see technical documentation smoke de-
tection system RMS) in connection with suitable electric
trigger devices of the fire damper is possible; only trigger
devices working by the "currentless closed" principle may
be connected to the RMS system; the propagation of fire
and smoke is effectively prevented and the requirements
of the Model Building Regulation (MBO) are fulfilled. Op-
timal integration into the building control system by
means of the SCHAKO EasyBus signalling and switching
bus system (see technical documentation EasyBus) or the
SCHAKO fire damper mini-controller BKSYS (see technical
documentation BKSYS).
ATTENTION
Building installations must be, among other things, erected,
modified and maintained in a way to prevent the formation of
fire and the propagation of fire and smoke (propagation of
fire) and to allow, in the event of a fire, human beings and
animals to be rescued and effective extinguishing work to be
carried out.
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 detec-
tion system RMS).

General information
 During mounting or installation, there is a risk of injuries.
To avoid any possible injuries, personal protective equip-
ment (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 re-
sult of thermal expansion (in case of fire).
Appropriate compensation measures, such as the ar-
rangement of flexible spigots (SCHAKO type FS) or a suit-
able duct routing (duct angles and distortions), must be
taken as required. National regulations must be obser-
ved and adhered to.
 Prior to installing the fire damper, the possible connec-
tions of the ventilation ducts must be checked. Extension
pieces (on site or as accessories SCHAKO type VT) may be
necessary, for example, for large wall and ceiling thick-
nesses. When connecting duct components, the type of
fastening must be selected such that no damage is
caused 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.
 If a fire damper is not filled with mortar on all four sides,
installation and mounting aids on site must be removed.
 Improper transport/handling may result in damage/func-
tional impairment. In addition to that, the film of the
transport packaging must be removed and the delivery in-
spected for completeness.
 In storage, fire dampers must be protected from dust, dirt,
moisture and the effects of temperature (e.g. direct sunlight,
heat-emitting light source, etc.). They must not be exposed
to direct effects of the weather and must not be stored be-
low -20 °C or above 50 °C.
 The fire damper must be protected from dirt and damage.
After installation is complete, any dirt must be removed im-
mediately.
 Enough space must be provided for installation, mortar lin-
ing, etc.
 Carry out a functional check of the fire damper before and
after mounting and ensure ready access.
 Electrical installations 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 se-
cured against being switched on again.
 On the non-operating side, either fastening materials (e.g.
screws, press-in nuts, etc.) must be provided and attached
for mounting duct components prior to installation of the
BKP-EN. Alternatively, extension pieces (on site or as acces-
sories, e.g. SCHAKO type VT) can be mounted.
 We would like to point out that only suitable cleaning mate-
rials 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 BKP-EN and may differ, depending on
the local situation.
To guarantee fire protection, the fire damper must be in-
stalled in accordance with the technical documentation, in-
stallation, mounting and operating instructions. The inspec-
tion opening of the fire damper must be freely accessible, oth-
erwise inspection openings in the connected ventilation ducts
must be provided in the immediate proximity. This must be
ensured in particular when at least 2 fire dampers are in-
stalled next to each other or below each other in the immedi-
ate proximity of adjacent components.
Figure 5: Minimum distances to walls and ceilings and BKP-
EN to one another
1.) Minimum distance recommended by SCHAKO for
sufficient accessibility
2.) The distance between the fire damper and the
adjacent component (wall/ceiling) must be determined
according to the particular installation situation or
adjusted to the dimensions of the projecting ends.
The dimension x is:
- manual trigger approx. 60 mm

Wet installation (mortar lining)
If 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
corresponding 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/ceiling, the annular gap dimensions can be
smaller than specified. 
The mortar bed depth must not be less than 130 mm.
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 ≥ 100 mm.

Wet installation with concrete base
• Construction of a circumferential, straight reinforced con-
crete base (concrete grade: C20/25; concrete cover ≥ 35
mm; reinforcement: concrete steel BSt500S concrete
steel mats B500A). The base must be constructed circum-
ferentially with a wall thickness of at least 100 mm, meas-
ured from the housing of the fire damper. The height of
the base must be maintained up to the prescribed instal-
lation dimension (200 mm). The maximum base height is
≤ 550 mm.
The damper leaf clearance of the installed fire damper
must be guaranteed. Make sure that there is nothing left
that may affect the function of the new fire damper.
Prior to installation of the fire damper, fastening materials
(e.g. screws, press-in nuts, etc.) must be provided and at-
tached on the non-operating side for mounting duct com-
ponents or, if subsequent mounting is no longer possible,
the ventilation duct must be connected prior to installa-
tion. Alternatively, extension pieces (on site or as acces-
sories, e.g. SCHAKO type VT) can be mounted.
During the formation of the concrete base on solid ceil-
ings, in addition to the constructive anti-crack reinforce-
ment, it must be ensured that the concrete base is applied
directly to the reinforced concrete ceiling or connected to
the raw ceiling.
Any separating layers (floor coverings, seals, insulations,
floating screeds, etc.) must be removed or must not be
present in this area.
During the construction of the concrete base, make sure
that the housing of the fire damper is not pressed inwards
(reinforcement).
• The minimum distance of fire dampers from one another
must be at least 200 mm.
• If an adjacent solid component (wall) is closer than 100
mm to the housing of fire damper, the existing gap to this
component must be filled as described above. This option
becomes available if the adjacent component has F90
characteristics.

Installation procedure
 Mount the metal posts and the wall in accordance with the
specifications of the wall manufacturer and the required ex-
change parts as shown on Figure 13.
 On both B sides of the exchange profiles (at the ⅓ points),
two drywall screws each must be attached to the metal pro-
files centrally at the wall as mortar anchor (pos. 14).
 Insert the BKP-EN into the wall recess (operating side - ob-
serve the installation dimension of 200 mm). Average out
the circumferential annular gap evenly between the wall
and the BKP-EN. Mount the BKP-EN with the help of mount-
ing suspensions, etc.
 Insert mortar (pos. 13) into the circumferential gap 40 mm
in width between the housing of the BKP-EN and the cir-
cumferential metal profiles (pos. 10). If reveals (pos. 15)
are used, the opening dimension must be adjusted accord-
ingly. For large wall thicknesses, a mortar bed depth of 130
mm is sufficient.
 After the mortar has set, the mounting aids (mounting sus-
pensions, etc.) must be removed.

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
connected to non-flammable or to flammable ventilation
ducts. Ventilation ducts must be suspended separately.
On the non-operating side, either fastening materials (e.g.
screws, press-in nuts, etc.) must be provided and attached for
mounting duct components prior to installation of the BKP-
EN. Alternatively, extension pieces (on site or as accessories,
e.g. SCHAKO type VT) can be mounted.
The local regulations or national standards on ventilation sys-
tems (in Germany e.g. LüAR) apply. In particular, 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 arrangement of flexible spigots
(SCHAKO type FS) or a suitable duct routing (duct angles and
distortions), must be taken as required. National regulations
must be observed and adhered to.
When using flexible spigots (SCHAKO type FS), the flexible part
of the spigot (polyester fabric) must have a minimum length
of lmin = 100 mm when mounted, resulting in an installation
dimension of approx. L = 160 mm. Alternatively, flexible ven-
tilation ducts can be connected.
