Fire Damper ETCE and ETCS - Instructions for Installation, Operation and Maintenance

Installation

Fire dampers ETCE and ETCS (with stainless steel casing)

must be installed according to this installation 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.

ETCE 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’s 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

should 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

automatic function testing interval for the motorized model

is 48 hours.

The operation of the fuse mechanism is tested by

pushing the red test button – the spring should close the

blade. Beware of the reset handle as it will rotate rapidly

during test operation. To reset the mechanism, turn the

handle until the mechanism clicks.

The function testing interval is always determined

separately for each building, but testing must be carried

out at least twice a year according to product standard EN

15650:2010.

Maintenance

According to product standard EN 15650:2010, ﬁre damp-

er installations and function are to be checked every six

months (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.

1. Install the duct in the usual manner so that it pene-

trates the building element, and seal the openings (M or

S) using an approved method.

2. Prepare the ﬁre damper for remote of wall installation:

Place the supplied accessory clamp collar ETCZ-1-

aaa-1 (3) as shown in Figure 11 over the taping on the

ﬁre damper and tighten it in place with the screws on

the clamp collar. NOTE. The custom-built clamp collar is

a mandatory accessory for installation outside building

elements.

3. Connect damper to duct according to the instructions

provided by the designer or manufacturer and remove

the blade supports. 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 installed next to the damper to enable

necessary cleaning and inspection.

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

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

ures 9-10) the dimensioning of threaded rod hangers

(1) can be done based on the following table. In vertical

installation (Figure 11) use shaft hangers (6) or other

approved methods to stabilize the damper according

to instructions from structural engineer. NOTE! The ﬁre

damper brackets (2) shall not be used for suspending

in the installation outside building elements.

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. The ﬁxings used to secure the ﬁre damper and ventila-

tion duct must have a ﬁre resisting capacity that is at

least as high as the ﬁre classiﬁcation of the penetrated

building element (the ﬁre resistance rating of a class

EI60 element is R60, etc.).

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.
