Warnings

Some damper parts may have sharp edges; therefore, to protect yourself, please use gloves during damper

installation and manipulation. In order to prevent electric shock, re or any other damage which could result from

incorrect damper usage and operation, it is important to:

1. ensure that installation is performed by a trained person.

2. follow the written and depicted instructions provided within this User Manual closely.

3. perform damper inspection in accordance with this User Manual.

4. check the damper’s functionality as per the
install the smoke damper. This procedure prevents the installation of a damper that has been damaged during
transportation or handling.

IMPORTANT: Do not install non-functioning dampers!

“Smoke Damper Functionality Check” chapter before you

Operating Conditions

S-SA2 and S-SA2L smoke dampers are intended:

• for installation in places which are protected against weather disruptions.

• for ducts, distributing air without any mechanical or chemical contamination.

• for a maximum air ow velocity 12 m/s.

• for a storage temperature range of -20°C to 50°C.

List of Accessories

• D1-S-SA2: Duct Extension with Mesh for S-SA2

• K1-S-SA2L: Kit for Sheet-Metal Duct Installation

Installation

• The duct connected to the smoke damper must be supported or hung in such a way that the damper does not

carry its weight. The damper must not support any part of the surrounding construction or wall which could cause
damage and consequent damper failure.

• The damper driving mechanism can be placed on either side of the wall, however, it needs to be situated to ensure

easy access during inspection.

• According to the EN 1366-2 standard, the distance between the smoke damper bodies must be at least 200 mm.

• According to the EN 1366-2 standard, the distance between smoke damper and the adjacent wall/ceiling

and the smoke damper must be at least 75 mm.

• The S-SA2 smoke damper must be installed into a smoke and re partition structure in such a way that the damper

blade is located inside this structure in its closed position. To help you nd the suspension plane, a bendable hinge

is provided on the damper body. This condition does not apply for S-SA2L.

• The gap in the installation opening between the smoke damper and the wall/ceiling can be increased by up to 50%

of the gap area, or decreased to the smallest amount possible that still provides sufcient space for the installation

of the seal.

• The gap between the damper blade in the open position and the self-standing grill (when installed) must be at least

200 mm according to EN 1366-10. Otherwise, the damper must be tested together with the grill.

• The smoke damper must be earthed after being installed into or onto the duct.

• Lists of all permitted installation methods are provided on the following pages. Every method only applies to those

damper types that are listed in the corresponding paragraph’s heading.

Installation Methods

All S-SA2 and S-SA2L smoke dampers are CE certied according to EN 12101-8:2011, tested according
to EN 1366–10 :2011+A1:2017, and classied according to EN 13501-4:2016.
The smoke damper, together with its installation, form an inseparable part of the re resistivity rating.

Standard Distances Between Damper Bodies

According to the EN 1366-2 standard, the minimum distance from the wall or ceiling to the damper body is 75 mm.

For multiple crossings through a re resistive wall, the minimum distance between two damper bodies is 200 mm.
This applies for distances between the damper body and a nearby foreign object crossing the re resistive wall.

Damper clearances vary from the type of mechanism and their rotation (please see Fig. 3 and see Tab. 5).

Wet Installation

Using Concrete Filling

Wet

1. The supporting construction opening must be prepared in a way depicted in the “Opening preparation” section

(as per Fig. 1 – Fig. 2). Opening surfaces must be even and cleaned. The exible wall opening must be reinforced

as per the standards for plasterboard walls. The opening dimensions are driven by the nominal dimensions of the
damper with added clearance. The opening will be made with dimensions W

and H1 ( Fig. 4 ).

1

2. Insert the closed damper into the middle of the opening so that the damper blade is in the wall. Use the bendable
hanger to secure the damper against the wall by using a suitable screw (3; recommended screw diameter 5,5;
e.g. DIN7981).

For damper widths greater than 600 mm, it is recommended to use a duct support inside the damper during

installation to avoid any damage to the damper housing from the weight of the lling.

3. Fill in the area between the wall and the damper with gypsum plaster, or mortar or concrete lling (2), while
paying attention to prevent the fouling of the damper’s functional parts, which could limit its correct functionality.

The best way is to cover the functional parts during installation. To prevent seepage of the lling material, the use

of boards is recommended.

First let the plaster, mortar or concrete lling harden and then perform the next steps.

4. After the lling hardens, remove the duct support from inside of the damper.

5. If needed, uncover and clean the damper after installation.

6. Check the damper’s functionality.
