These technical specifications state a row of manufactured sizes and models of fire dampers (further only dampers)
CFDM. It is valid for production, designing, ordering, delivery, assembly and operation.

Fire dampers are shutters in duct systems of air-conditioning devices that prevent spreading the
fire and combustion products from one fire segment to the other one by means of closing the air
duct in the points of fire separating constructions.
Dampers blade automatically closes air duct using a shutting spring.
The damper is sealed with a plastic foam packing against smoke penetration after closing the
blade. At the same time, the damper blade is bedded in a material which enlarges its capacity
and air´proofs the air duct.
Damper characteristics
• CE certified acc. to EN 15650
• Tested in accordance with EN 1366-2
• Classified acc. to EN 13501-3+A1
• Fire resistance EIS 120, EIS 90, EIS 60
• Internal leakage class 2 acc. to EN 1751, external leakage is equal to ducting system
• Corrosion resistant acc. to EN 15650
• ES Certificate No. 1391-CPR-2016/0082
• Declaration of Perfomance No. PM/CFDM/01/16/1
Working conditions
Exact damper function is provided under the following conditions:
a) Maximum air circulation speed: 12 m.s
Maximum pressure difference: 1500 Pa
b) The air circulation in the whole damper section must be secured as steady on whole
surface.
Operation of the damper does not depend on the direction of air circulation. The dampers can
be located in an arbitrary position.
Dampers are suitable for ventilation systems, where air does not content any abrasive, chemical
or adhesive particles.

Design .01 with mechanical control can be equipped by one or two limit switches signalling
position of the damper blade "CLOSED". Limit switch is connected via duct.

Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3.
Temperature in the place of installation is permitted to range from - 20°C to + 50°C.
Design with mechanical control
Design with mechanical control with a thermal protective fuse (inner mechanical control which
actuates the shutting device within 120 seconds at latest after the nominal start temperature
72 °C has been reached. Automatic initiation of the shutting device is not activated if the
temperature does not exceed 70 °C.

Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating constructions. Duct assembly procedures must be done so as all load transfer
from the fire separating constructions to the duct in the placement of fire damper installation is
absolutely excluded. Installation gap must be filled by approved material perfectly in all the
installation space volume (installation gap).
To provide needed access space to the control device, all other objects must be situated at least
350 mm from the control parts of the damper. Inspection hole must be accessible.
Damper has to be accessible for regular checks and maintenance.
Fire damper is inserted inside the duct. Blade has to be inside of fire separating
construction (after closing).
The distance between the fire damper and the construction (wall, ceiling) must be at least 75 mm.
In case that two or more dampers are supposed to be installed in one fire separating construction,
the distance between the adjacent dampers must be at least 200 mm according to EN 1366-2
paragraph 13.5.

Installation opening dimensions (see Fig. 9-11)
Examples of fire damper installing
The fire damper can be integrated into a solid wall construction made e.g. of normal concrete/
masonry, porous concrete with minimum thickness 100 mm or into solid ceiling construction made
e.g. of normal concrete with minimum thickness 110 mm or porous concrete with minimum
thickness 125 mm.
The fire damper can be integrated into a gypsum wall construction with fire classification
EI 120 or EI 90.

The appliance is constructed and preset by the manufacturer, its operation is dependent on
proper installation and adjustment.
Dampers are transported by box freight vehicles without direct weather impact, there must not
occur any sharp shocks and ambient temperature must not exceed + 40 °C. Dampers must be
protected against mechanic damages when transported and manipulated. During transportation,
the damper blade must be in the "CLOSED" position.
Dampers are stored indoor in environment without any aggressive vapours, gases or dust. Indoor
temperature must be in the range from -5 °C to +40 °C and maximum relative humidity 80 %.
Dampers must be protected against mechanic damages when transported and manipulated.
All effective safety standards and directives must be observed during fire damper assembly.
To ensure reliable fire damper function it is necessary to avoid blocking the closing mechanism
and contact surfaces with collected dust, fibre and sticky materials and solvents.
Before entering the dampers into operation after their assembly and by sequential checks, the
following checks must be carried out.
Visual inspection of proper damper integration, inside damper area, damper blade, contact
surfaces and silicon sealing.
