1. INTRODUCTION
The purpose of technical documentation is to familiarize the user with the
intended use, design, operation principle, installation, periodic maintenance and
operation of product.
2. LEGAL REGULATIONS
Fire dampers KWP-L have Certificate of Constancy of Performance No.
1438-CPR-0509, issued by Scientific and Research Centre for Fire Protection –
National Research Institiute.
KWP-L fire dampers are designed for application in general ventilation
systems as isolation baffles separating the fire-engulfed zone from the remaining part
of the building (normally open). The purpose of these dampers is to prevent the spread
of fire, heat and smoke.
The dampers are designed, manufactured and tested in accordance with the
following standards: PN-EN 15650 “Ventilation for buildings - Fire dampers” and PN-
EN 13501-3 “Fire classification of construction products and building elements - Part
3: Classification using data from fire resistance tests on products and elements used
in building service installations: fire resisting ducts and fire dampers“.
The effectiveness of the dampers is confirmed by tests according to PN-EN
1366-2 “Fire resistance tests for service installations - Part 2: Fire dampers.
KWP-L fire dampers are classified as integrity class C (housing integrity) on
the basis of tests carried out according to PN-EN 1751 “Ventilation for buildings. Air
terminal devices. Aerodynamic testing of dampers and valves.“
3. INTENDED USE
KWP-L fire dampers are classified in the following fire resistance range and can
be mounted in the following space dividers:
•EI 120 (ve ho i↔o) S
oceilings having density of 2200±200 kg/m3or more, thickness of 140 mm or
more, and in fire resistance class EI120 or higher,
origid walls with small density (650±200 kg/m3) or more, thickness of 100
mm or more and in fire resistance class EI120 or higher (e.g. concrete
walls, non-hollow brick walls, cellular concrete block walls, hollow
masonry unit walls or concrete slab walls),
•EI 90 (ve i↔o) S
ostandard walls, thickness 100 mm or more and in fire resistance EI90 or
higher (thicker, greater density, more slab layers),
origid walls, thickness 100 mm or more and in fire resistance EI90 or higher
(e.g. concrete walls, non-hollow brick walls, cellular concrete block walls,
hollow masonry unit walls or concrete slab walls),

Page 5 z 25
DTR – KWP-L
Version: 1.0
•EI 60 (ve i↔o) S
ostandard walls, thickness 75 mm or more and in fire resistance EI60 or
higher,
origid walls, thickness 75 mm or more and in fire resistance EI60 or higher
(e.g. concrete walls, non-hollow brick walls, cellular concrete block walls,
hollow masonry unit walls or concrete slab walls),
•EI 30 (ve i↔o) S
ostandard walls, thickness 75 mm or more and in fire resistance EI30 or
higher (thicker, greater density, more slab layers),
origid walls, thickness 75 mm or more and in fire resistance EI30 or higher
(e.g. concrete walls, non-hollow brick walls, cellular concrete block walls,
hollow masonry unit walls or concrete slab walls),
where:
E– integrity,
I– insulation,
S– smoke leakage,
120/90/60/30 – duration of fulfilment of E, I and S criteria, expressed in minutes,
ve – damper mounted directly in the wall,
ho – damper mounted directly in the ceiling,
i↔o– operating effectiveness criteria are fulfilled from the inside to the outside (fire
inside), and from the outside to the inside (fire outside).
KWP-L fire dampers may also be installed in space dividers having a smaller fire
resistance. In this case, the damper`s fire resistance is equal to the space divider`s
fire resistance, considering the smoke leakage criterion.
KWP-L fire dampers may be installed in vertical space dividers with both horizontal
and vertical rotation axis of damper blade, with any actuator location.
4. TECHNICAL DESCRIPTION
KWP-LS dampers (with a spring mechanism) and KWP-LE dampers (with
electric actuator and return spring) comprise a housing, square in profile, moving,
single-axis isolating baffle and actuating mechanism with a release device.
The damper housing and its interacting elements are made of galvanised steel
sheet. Both ends of the housing are terminated with connection flanges, allowing easy
connection between the duct and the damper.
There are intumescent seals on the outer and inner surface of the housing, in
the place of perforation around the closed isolating baffle. Their characteristic feature
is the fact that their volume increases at high temperatures, tightly filling all leaks
between the baffle and the body.
The isolating baffle of the damper is made of calcium-silica board, and a bubble
seal is installed on its perimeter, ensuring the damper’s integrity in the ambient
temperature.
The KWP-L damper is provided with a spring mechanism, comprising e.g. the
actuating spring, manual release device, and a thermal fuse whose nominal activation

Page 6 z 25
DTR – KWP-L
Version: 1.0
temperature is 70±5°C. When the damper is opened with a key, the actuating spring is
tensioned. The baffle is kept in open position by the automatic release device,
interlocked with a thermal fuse. The damper is automatically closed by the release
device. Damage to the thermal fuse automatically rotates the isolating baffle (to closed
position) as a result of decompression of the actuating spring. The movement of the
rotating baffle is limited by two resistance buffers.
KWP-LE damper is provided with an electric actuator and BFL or BFN series
return spring by BELIMO, and BAT thermal fuse (72°C, optionally 95°C), constituting
the damper’s actuating system having supply voltage AC 230V or AC/DC 24V. After
voltage is supplied, the actuator rotates the baffle into the position. The baffle is closed
when the voltage is lost, or when the thermal fuse is activated (the return spring in the
actuator closes the baffle by returning to a non-stressed position).
During normal operation of the system, KWP-LS and KWP-LE dampers are in
open position. If a fire breaks out, the damper’s baffle rotates to a closed position.
The type series of the dampers covers the following dimensions: clear damper
width from 200 to 800 mm (50 mm intervals) and clear damper height from 200 to
500 mm (50 mm intervals). The primary type series of damper dimensions, including
actuators, is provided in the table below.

BFL actuators are used for the damper clear area of ≤ 0,24 m2.
BFN actuators are used for the damper clear area of >0,24 m2.
BF actuators are used for all series fire dampers.
Depending on the actuation system used, the dampers are marked as follows:
•KWP-LS - damper with spring mechanism,
•KWP-LE - damper with electric actuator and return spring,
The length of KWP-L dampers is L=350 mm.
The dampers mas also be fitted with limit switches indicating open or closed position
of the baffle.
In the special version, resistant to aggressive environments, the damper`s baffle is
impregnated with a special substance used for fire-resistant board impregnation.

6. CONDITIONS OF TRANSPORT AND STORAGE
Fire dampers KWP-L should be stored in cardboard boxes and/or on pallets.
KWP-LE should have a pre-protected actuator cardboard box. Fire dampers should be
stored indoors, providing protection against atmospheric agents, at a minimum
temperature of +5°C.
Do not allow mechanical damage of damper, that may be caused e.g. blows or
dropping.
After each transport, visual inspection of each fire damper must be carried out.
7. INSTALLATION TECHNOLOGY
Before installing the fire dampers, make sure that there are no damage, during
transport or storage, that could block the damper blade.
Check that the damper blade can be opened and closed (full opening and closing
position). To open fire dampers KWP-LE use the actuator key.
The opening and closing must proceed smoothly (not stepwise).
Do not pull by damper blade to open or close fire damper, it may cause
permament damage, not covered by the warranty.
To opening fire dampers KWP-LS use a key, mounted on damper casing.
Before installing, secure the fire damper, by dust and dirt, using a foil or other
screening material. It can prevent components of fire damper by damage.
7.1 Installation technology - Ceiling
1. Make an opening in the ceiling with the dimensions 120 mm greater than the
nominal dimensions of the fire damper, i.e. B+120 and H+120.
2. Put the fire damper into the installation opening and support or suspend, in this
way that an axis of the fire damper blade matches the axis of the ceiling, and
ensure a concentricity of fire damper and mounting hole.
3. After setting the fire damper as described, mounting the mounting brackets, fill
the gap between the fire damper and the ceiling with cement, cement-lime mortar
or concrete.
4. After the mortar has dried (about 48 hours), remove the supports or suspenions,
check the fire damper correct operation and leave it in open position.
