DESCRIPTION
Fire dampers, installed in ventilation ducts (air conditioning
systems), serve for the automatic locking of fire lobbies.
The fire damper BSK-EN complies with EN 15650, EN 13501-3
and EN 1366-2.
BSK-EN is tested according to EN 1366-2 in connection with
Declaration of performance (DoP) no. 01-01- DoP- BSK-EN-
2014-10-29.
It has the certificate of consistency of performance no. 1035-
CPR-ES054987 according to EU-BauPVO.
Category according to EN 13501-3 is EI 120 (v
e
, h
o
i↔o) S.
The national standards and directives must be observed in
connection with the technical documentation Installation,
mounting and operating instructions. For maintenance, ser-
vice, retrofitting, etc., maintenance openings must be provi-
ded on site in suspended ceilings, shaft walls, connected ven-
tilation ducts etc., if necessary. They must be built in in suffi-
cient 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 both on non-combustible and com-
bustible ventilation ducts.
MODELS
• Housing made of galvanised sheet steel, cold and hot
leakage requirements according to EN 1366-2 are met u-
sing circumferential PUR sealings and intumescent seals.
Optionally (at an extra charge) with DD coating (two-com-
ponent paint, PU-based), inside/outside.
• Moulded connecting flanges with centre hole, corner angle
with long hole for simple channel mounting and high sta-
bility.
• Shut-off damper made of fibre-silicate board.
• Thermal release via fusible link 72°C or 98°C.
• Optimum integration in the building control system using
SCHAKO signalling and switching bus system EasyBus (see
technical documentation EasyBus).
• Application: operating pressure max. 1000 Pa at v
stirn
≤ 10
m/s.
• The installation position does not depend on the air flow
direction.
MAINTENANCE INFORMATION
We would like to point out that only suitable cleaning materi-
als may be used to clean the stainless steel version of fire dam-
pers!
ATTENTION
Building systems have to be arranged, installed and maintai-
ned in such a way that they prevent fire and propagation of
fire and smoke (fire propagation) and allow evacuation of per-
sons and animals as well as efficient fire extinguishing work.
Spreading of smoke through the ventilation and air condition-
ing systems can be efficiently prevented only with suitable
electrical triggering device in combination with a smoke detec-
tion system.
Therefore, we recommend to equip fire dampers, for example
with spring return actuators that can be triggered by the
smoke detector.

MOUNTING INFORMATION
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 board walls according
to EN 12859 or DIN 18163; apparent density ≥ 450 kg/m³
and wall thickness W ≥ 150 mm.
• Installation with horizontal damper leaf.
• Circumferential gaps "s" must be filled completely with
mortar of categories M2.5 to M15 according to EN 998-2,
NM II to III DIN V 18580 (previously: MG II to III according
to DIN 1053) or fire protection mortar of the correspon-
ding grade or with concrete suitable for the wall type. The
minimum gap size s
min
is 50 mm. If the fire damper is in-
stalled during the construction of the wall, the gaps "s" can
be omitted. The mortar bed depth has to be designed ac-
cording to the minimum wall thickness and may not be less
than this thickness.
• The distance between the fire dampers must be min. 200
mm.
• Distance to the bearing adjacent components (wall / solid
ceiling) is minimum 75 mm.
INSTALLATION IN SOLID CEILINGS
• Installation in solid ceilings, for example made of concrete,
foam mortar; apparent density ≥ 500 kg/m³ and ceiling
thickness D ≥ 150 mm.
• Installation with full mortar lining (circumferential gaps "s"
must be filled completely with mortar of category M15 ac-
cording to EN 998-2, NM II DIN V 18580 (previously: MG III
according to DIN 1053) or fire protection mortar of the cor-
responding grade. The minimum gap size smin is 50 mm. If
the fire damper is installed during the construction of the
ceiling, the gaps "s" can be omitted. The mortar bed depth
has to be designed according to the minimum ceiling thick-
ness and may not be less than this thickness.
• The distance between the fire dampers must be min. 200
mm.
• Distance to the bearing adjacent components (wall) is mi-
nimum 75 mm.

CONNECTION OF VENTILATION DUCTS
The fire dampers must be connected to the ventilation ducts
of the ventilation system either on one or on both sides. For
one-sided connections, finishing protective grating made of
non-combustible material (EN 13501-1) must be provided on
the respective opposite sides. The fire dampers can be
connected both to non-combustible and combustible
ventilation ducts.
The local regulations or national standards on ventilation
systems (in Germany e.g. LüAR) apply.
No inadmissible forces may affect the fire damper and space-
enclosing components especially in case of fire and impair
their fire resistance time. The required expansion joints
(flexible connecting pieces) must be designed as flammable,
elastic connecting pieces made of at least standard
inflammable materials (EN 13501-1) and installed between the
fire damper and ventilation duct. Flexible part of the
connecting piece (polyester fabric) must have the minimum
length of l
min
= 100 mm in the mounted state, this gives a
mounting dimension of approx. L = 160 mm. As an alternative,
instead of installing flexible connecting pieces, flexible
ventilation ducts made of aluminium can be connected.
Ventilation ducts must be suspended separately.

INSTALLATION INFORMATION
MINIMUM DISTANCES
The specified dimensions should be considered as installation
recommendation for BSK-EN and can deviate depending on
the location. The fire damper must be installed to ensure fire
protection according to the technical documentation Installa-
tion, mounting and operating instructions. Inspection ope-
nings are not available, therefore, they must be created in the
direct vicinity in the connected ventilation ducts. Inspection o-
penings are not available, therefore, they must be created in
the direct vicinity in the connected ventilation ducts. Inspec-
tion openings must be freely accessible, ensure this especially
when installing minimum 2 fire dampers next to each other or
below each other or when installing them in the direct vicinity
of bearing adjacent components.

Electric spring return actuator with thermoelectric release
device BAT or BAE72B-S.
• Release temperature 72°C optional 95°C and 120°C (for
hot-air heating).
• 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 fu-
ses (ambient temperature or internal duct temperature)
respond. Reaction of the thermal fuses interrupts the
supply voltage permanently.
• Display of the damper end positions is possible by means
of integrated micro switches via potential-free changeover
contacts (S1 – S3 "CLOSED" indicates the closed position;
S4 – S6 "OPEN" indicates the opened 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 or BAE72B-S.
• Spare parts: Temperature fuse for temperature inside the
duct 72°C/95°C/120°C (ZBAT72 or ZBAE72 and ZBAT95 or
ZBAE95 and ZBAT120). Exchange takes place by unscre-
wing the two screws of the thermoelectric release device.
Remove the thermoelectric trigger device from the actua-
tor unit. Remove the internal duct temperature fuse from
the thermoelectric release device and replace it with a new
internal duct temperature fuse (ZBAT... or ZBAE...). Screw
the thermoelectric trigger device back onto the actuator
unit. For any other damage, the entire "actuator/thermal
release device" unit must be replaced completely.
Electric spring return actuator with thermoelectric
trigger device BAE72TL.
• Trigger temperature 72°C optionally 95°C (for hot-air hea-
ting).
• Supply voltage 24V AC/DC including connector.
• Connection to LON or Belimo MP bus systems is possible
via communication and power supply units BKN230-24LON
or BKN230-24MP.
Further technical data are available on request.
The safety function is only guaranteed if the
drive has been connected to the supply vol-
tage in accordance with regulations.

MAINTENANCE OR FUNCTIONAL TEST
Unclean and humid air can impair the continuous operational
safety. Therefore, after commissioning of the ventilation in-
stallation, the function of all fire dampers must be checked
semi-annually.
If two consecutive functional checks do not show any defects,
the fire dampers only have to be tested once a year. If mainte-
nance agreements are made, for example for ventilation in-
stallations, it is recommended to include the functional tests
of the fire dampers in these maintenance agreements.
1. Manual trigger device
1.1 External check
1.1.1 Visual inspection
• Check the fire damper for damage and contamination.
• Perform necessary cleaning work.
1.1.2 Manual triggering – Closing the fire damper
• Pull the disc (pos. 1) at the hand lever (pos. 2), this releases
the locking (in the open position) of the locking bolt (pos.
4) in the trigger device (pos. 3).
• The hand lever is released and is moved by spring force in
the direction of the closed position.
ATTENTION! Do not reach into the swivelling range of the
damper leaf and hand lever. There is a risk of injury.
• The fire damper must close automatically.
1.1.3 Test of the snap-in locking device
• Pull the disc (pos. 1) at the hand lever (pos. 2) in the closed
position and release it again.
• The return must be performed automatically.
1.1.4 Fire damper open
• Pull the disc (pos. 1) at the hand lever (pos. 2) and move it
in the direction of the trigger device (pos. 3).
• The locking pin (pos. 4) must engage in the trigger device
(pos. 3).
• The fire damper is ready for operation again.
• After successful manual triggering, repeat the process se-
veral times as described in section 1.1.2.
1.2 Internal check
1.2.1 Visual inspection
• Check the fire damper for damage and contamination.
• Perform necessary cleaning work.
1.2.2 Check of the trigger device
• Perform manual triggering as described in section 1.1.2.
• Remove the fastening screws (2 pieces) (pos.5), pull the
trigger device out of the housing.
• Contract the fusible link holder (pos. 6) by means of a sui-
table tool (pliers, vice etc.) and removed the fusible link
(pos. 7).
• Check the fusible link; if no damage is visible, insert the
fusible link again.
• Install the trigger device again and tighten it by means of
screws.
