Smoke extract dampers - multi are shutters in the smoke exhaust piping systems. The dampers are

designed to remove heat and combustible products (e.g. smoke) from fire compartments. The

damper blade is controlled by actuating mechanism. The dampers are designed for using in fire

compartments that can be connected to the smoke exhaust ducts (tested according to EN 1366-8)

or they can be installed in or on the construction of the fire compartment.

Dampers are classified according to EN 13501-4.

In the event of fire the Smoke and Fire Ventilation System opens the damper in the affected section

which removes combustion products and heat from this section.

Fire dampers are suitable for installation in arbitrary position (axle of the blade as horizontal or

vertical). The Air Flow (smoke) must be directed from the control device side (see arrow on the

damper body).

Dampers are designed for macroclimatic areas with mild climate according to EN 60 721-3-3 zm.A2.

1. During installation the damper blade must be in position "CLOSED". The damper body should

not be deformed in the course of bricking in. Once the damper built in, its blade should not grind

on the damper body during opening or closing.

2. The installation of more dampers into the fire separating construction must meet the following

requirements:

- the minimum distance between two dampers has to be 200 mm;

- the minimum distance between damper and construction (ceiling / wall) has to be 75 mm;

3. During installation the control mechanism must be protect against damaged and pollution.
