Fire Damper ETPR - Instructions for Installation, Operation and Maintenance

Maintenance Check List:

Installation

Fire damper ETPR must be installed according to this in-

stallation manual, see pages 4-9.

General instructions for using hangers

The ﬁre damper must be supported so that the ductwork

connected to the damper does not impose any load on the

damper body.

In practice, a good way to ﬁt the product centrally in the

installation opening is to hang the ductwork prior to sealing.

If the subsequent sealing is done using grouting concrete,

also other types of support can be used during installation

until the concrete has dried.

It is essential that no stress is imposed on the ﬁre damper

or the duct. The hanging and ﬁxing solution must be ade-

quate in the event of ﬁre. The hanger must be located either

at the ﬁre damper or immediately after the duct connection.

Designing the use of hangers is the responsibility of a

structural engineer.

Operation and function testing

According to CE marking, a ﬁre damper must always be

equipped with a tripping mechanism based on temperature.

Fire dampers can be delivered equipped with either a fuse

mechanism or an actuator.

ETPR motorized ﬁre dampers may additionally be linked to

a smoke detection based tripping mechanism. A tripping

system based on smoke detection is easy to install using

FläktGroup FICO control and monitoring system. The FICO

system can also be used for automatic function tests of ﬁre

dampers.

The function testing for the motorized damper can be per-

formed by cutting off the power supply by using the switch

of the thermal trip connected to the motor. The spring will

then close the damper. The function testing can also be

done by means of the control and monitoring system FICO,

either manually or automatically. The recommended auto-

matic function testing interval for the motorized damper is

48 hours.

The operation of the fuse mechanism is tested by pushing

the red test button – the spring will close the blade. Beware

of the reset handle as it will rotate rapidly during test op-

eration. To reset the mechanism, turn the handle until the

mechanism clicks.

Maintenance

The function testing interval is always determined separate-

ly for each building, but testing must be carried out at least

twice a year according to product standard EN 15650:2010

(see example of check list beside).

WARNING! Never put your hands inside the damper while

it is closing.

Clean the ﬁre damper by means of a vacuum cleaner. Avoid

chemical cleaning agents.

2. The ﬁre damper blade must be closed during installa-

tion.

3. Place the circular duct centrally in the opening.

4. Place the ﬁre damper in the duct so, that the damper

ﬂange rests against the building element and connect

the damper to duct. Use screws of sufﬁcient length (e.g.

M6 x 40 mm), which are suited for rigid construction, to

fasten the damper to the building element through the

bendable brackets on the ﬂange. The damper must be

fastened at 4 brackets at the minimum. The blade shaft

can be placed in any position.

5. Completely ﬁll the gap M between the duct and the

building element using incombustible, rock based, ﬁne-

grained gypsum or concrete cast. Protect the damper

whilst inﬁlling.

2. The ﬁre damper blade must be closed during installa-

tion.

3. Place the circular duct in the opening.

4. Fill the gap S between duct and wall opening on both

sides by using ﬁre-resistant mass.

5. Place the ﬁre damper in the circular duct so, that the

damper ﬂange rests against building element and

connect the damper to duct. Use screws or anchors

suited for gypsum board walls to fasten the damper to

the building element through the bendable brackets on

the ﬂange. The damper must be fastened at 4 brackets

at the minimum. The blade shaft can be placed in any

position.

6. Check the functioning of the ﬁre damper and proper

movement of the blade. Clean the damper, if necessary.

Place plastic covers on the openings and keep them

covered, until ducts are connected to the damper.

7. To reset the fuse mechanism: Turn the handle towards

the OPEN position until the mechanism clicks and the

blade locks into position.

8. Manual function testing of the motorized ﬁre damper

can be performed with the tool delivered with the

actuator. When connected to a power supply, function

testing is done by using the switch of the thermal trip.

NOTE! If you open the damper blade manually with the

tool, be sure to release the damper back to the closed

position before switching on power.

9. Connect ducts to the damper according to the instruc-

tions provided by the designer and the manufacturer.

Use rivets of sufﬁcient length (e.g. DIN 7337 4x10 or

shorter) to lock ﬁre damper to the duct. Note! Always

check that damper blade can rotate freely and rivets/

screws are out of the way. Access panel should be

placed next to the ﬁre damper to enable necessary

cleaning and inspection. Suspend the ducts according

to instructions from the manufacturer and ensure that

the ductwork does not cause any load on the damper

installation.

10. If the ﬁre damper is used as an air transfer or air

terminal device, it must be equipped with a protective

grille. The distance between the grille and the damper

blade in the open position must be at least 30 mm. In

case of large ﬁre dampers, an extension piece must

be installed between the grille and the damper blade.

A circular duct of suitable length can be used as an

extension piece.

11. When dampers are to be mounted next to one another,

the distance between the dampers should be ≥200mm

(Figure 4).

er blade can rotate freely and rivets/screws are out of

the way. Access panel should be installed next to the

damper to enable necessary cleaning and inspection.

3. Support the duct installation so that there is no extra

load on the ﬁre damper. In horizontal installation (Fig-

ures 5-6) the dimensioning of threaded rod hangers (1)

can be done based on the following table. In vertical

installation (Figure 7) use shaft hangers (2) or other

approved methods to stabilize the damper according to

instructions from structural engineer.

4. Insulate the duct between wall and ﬁre damper ﬂange

as shown in ﬁgures 5-7, so that the ﬁre classiﬁcation EI

60 is met.

Installation of ﬁre damper into sandwich-type* building elements with ﬁre

classiﬁcation EI60 (Fig. 8-11)

Make a circular opening on the side where the ﬁre

damper will be installed and a square opening on the

opposite side. Note! For a successful installation, it is

important that the openings are aligned.

2. Prepare the installation opening by cutting it completely

clear of wool from the square side so that only the

facing of the element is visible. Use ﬁre-rated acrylic

sealant to seal the corners of the square opening as

well as any element joints at the installation opening

(see red markings in Fig. 8).

3. Install mounting rails (4 pcs) of L30x30x2, e.g. Wurth

0862001905, (see No. 1 in Fig. 8) on all edges of the

square opening. Use sharp-point screws, e.g. Wronic

4.2x38mm, at intervals of approximately 80mm. To

reinforce the corners of the opening, drill a 6 mm hole

at each corner through the opening in the mounting rail

and all the way through the element. Provide the holes

with through bolts of M6 x 120mm or M6 threaded

rods (4 pcs) and tighten them into place using washers

and nuts (see No. 2 in Fig. 8).

9. Check the functioning of the ﬁre damper and proper

movement of the blade. Clean the damper, if necessary.

Place plastic covers on the openings and keep them

covered, until ducts are connected to the damper.

10. To reset the fuse mechanism: Turn the handle towards

the OPEN position until the mechanism clicks and the

blade locks into position.

11. Manual function testing of the motorized ﬁre damper

can be performed with the tool delivered with the

actuator. When connected to a power supply, function

testing is done by using the switch of the thermal trip.

Note! If you open the damper blade manually with the

tool, be sure to release the damper back to the closed

position before switching on power.

12. Connect ducts to the damper according to the instruc-

tions provided by the designer and the manufacturer.

Use rivets of sufﬁcient length (e.g. DIN 7337 4x10 or

shorter) to lock ﬁre damper to the duct. Note! Always

check that the damper blade can rotate freely and

rivets/screws are out of the way. Access panel should

be placed next to the ﬁre damper to enable necessary

cleaning and inspection. Suspend the ducts according

to instructions from the manufacturer and ensure that

the ductwork does not cause any load on the damper

installation.

13. If the ﬁre damper is used as an air transfer or air

terminal device, it must be equipped with a protective

grille. The distance between the grille and the damper

blade in the open position must be at least 30 mm. In

case of large ﬁre dampers, an extension piece must

be installed between the grille and the damper blade.

A circular duct of suitable length can be used as an

extension piece.

1. Installation openings in the element must comply with

Figure 8 and the dimensions given in the table below.

4. If there are any element joints at the installation open-

ing or within 800mm of any of its edges, seal these

joints on both sides with ﬁre-rated acrylic sealant and

secure them with sharp-point screws, e.g. Wronic

4.2x38mm, at intervals of 100mm

(see No. 3 in Fig. 8)

5. Install the product and the duct. The ﬁre damper blade

must be closed during installation. Insert the duct

through the square opening and all the way through

the wall, and connect the ﬁre damper to the duct (see

Fig. 9).

6. Seal the surface of the calcium silicate ﬂange around

the ﬁre damper with ﬁre-rated acrylic sealant where

it will be attached to the element (see Fig. 10). Place

the duct centrally in the opening. Press the ﬁre damper

against the element, and ﬁx it to the element surface at

the foldable brackets (4 to 6 pcs) using blind rivets (e.g.

steel rivets of 4.8x14mm (see Fig. 11).

7. Seal the edge of the calcium silicate ring against the

element surface with ﬁre-rated acrylic sealant (see Fig.

11 and detail in Fig 10, the red markings).

8. Insulate the square installation opening with two layers

of Paroc HVAC Fire Slab EI 120 with a thickness of

60mm, the total insulation thickness being 120mm

(see No. 4 in Fig. 9). Cut the wool layers according to

Figure 9 and the table in step 1 above. Seal all joints

and edges in both insulation layers with ﬁre-rated

acrylic sealant (see red markings in Fig. 9). Any insu-

lation slab surfaces that remain visible can be treated

with, for example, a ﬁre-resistant paint if necessary.
