Pressure drop and sound data

Sound power level Lw, in in each octave band is

computed bu adding the corresponding correction

factor, Kok, to the sound pressure level in the

selection chart according to the following equation.

Lw = LpA + Kok

The corresponding factor Kok is the average of the

FDR operating area.

Material and finishing

The FDR fire damper casing, installation flange, and

installation frame are made of galvanised steel. The

closing blade is made of calcium silicate and equipped

with a flexible silicone seal as well as a graphite mass

seal that expands at high temperatures.

Product options and Accessories

Function

The FDR is a fire damper of class EIS 30 to EIS 120

for circular or rectangular ducts, which prevents fire

and smoke from spreading in ventilation ducts. The fire

damper is equipped with either a motorised actuator

or manual actuation arrangement. Both actuators

have a visual position indicator. If the power in the

motorised actuator system is switched off, the blade

closes automatically.

Europe and Russia models:

In both actuator options, a fuse reacts to a rise in

temperature, causing a spring-return blade to close.

The motorised fire damper is delivered complete with

a spring-return actuator and a fuse that is activated at

72 ºC.

Sweden model:

The electrical motor option is without thermal fuse

and shall be connected to an automatic alarm system.

The fire damper is made of fireproof materials. Once

the fire damper has closed, the double sealing closes

the duct tightly, effectively preventing the spreading

of flue gases in the ventilation ductwork. The flexible

seal of the double sealing system operates at lower

temperatures, while the graphite mass seal expands

to insulate the system at temperatures above 150 ºC.

The FDR fire damper can be connected to the MSH

control and testing system for fire dampers. The

MSH unit enables the use of smoke detectors in the

ductwork or rooms. The FDR fire damper can also

be connected to other common building automation

systems.

Installation

Installation on masonry walls

When the fire damper is installed on concrete

and masonry walls and ceilings between fire

compartments, the blade shaft is always horizontal.

An opening is always left in the separating element

for the fire damper, and the product is subsequently

grouted into this.

To make installation easier, all products come with

an installation flange, which is used to fasten the fire

damper to the concrete surface with screws before

grouting.

During installation, the fire damper and actuator must

be protected with, e.g., a plastic cover.

The correct operation of the fire damper must be

ensured before and after grouting.

When the damper is installed for concrete and

masonry walls and ceilings, the size of the installation

hole is W/H + 100 mm.

Installation on lightweight plasterboard walls

When the fire damper is installed on lightweight

plasterboard walls between fire compartments,

an opening for the fire damper must be left on the

plasterboard in which the installation frame (included

in the delivery) is first mounted. The blade shaft must

always be horizontal. To make installation easier, the

fire damper comes with an installation flange, which

is used to fasten the fire damper to, e.g., the steel

frame of the panel wall. The space between the fire

damper and the installation frame is filled with a fire

prevention mastic. During installation, the fire damper

and actuator must be protected with. e.g., a plastic

cover. The correct operation of the fire damper must

be ensured after application of the fire prevention

mastic.

For lightweight walls, the size of the installation hole

is W/H+110 mm; consult the section ‘Documents /

Installation Instructions’ for the size of the installation

holes.

20/FDR/3500/0907/EN

Detailed installation instructions, as well as an

installer’s installation certificate form, are supplied

with each product. See also the section ‘Documents /

Installation Instructions’.

Suggested specifications

A fire damper of class EIS 30 to EIS 120 shall have

a double sealing solution that ensures fire-gas

resistance at all temperatures when the fire damper is

closed.

In motorised models, the fuse shall be activated at 72

°C (E and R models).

In the manually operated system, the fuse activation

temperature corresponds to the specifications (50, 65,

72, 100 °C).

The fuse shall be located inside the damper, and it

shall be possible to replace it from the outside.

The fire damper shall have means for external opening

/ triggering of the release and closing. The fire damper

shall include a position indicator.

The fire damper shall be suitable for vertical and

horizontal installation on concrete and masonry walls

and on ceilings or lightweight plasterboard walls

between fire compartments (EIS 30 to EIS 120).

The technical properties of the type-approved fire

damper shall conform to the EN 1366-2 and EN

13501-3 standards.

The internal quality control of the fire damper

manufacturer shall be based on the ISO 9001

quality system system, and the operations of the

manufacturer shall be subject to external third-party

quality control.
