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.

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).

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.

, thickness as opening gap).

First apply a suitable re resistive coating (5; CFS-CT {HILTI}) onto the damper at the place of its future placement,
assemble and glue the lling of the future installation with the same re resistive coating.
After the re resistive coating has dried, the damper along with the lling are ready for installation.

4. Apply the same re resistive coating (5) onto the internal surface of the wall opening. Also apply the re resistive
coating to the external surface of the lling glued to the damper surface. Immediately after applying the re

resistive coating, place the damper into the wall opening. The damper blade must be located in the supporting

structure. Then x the damper using the bendable bracket.

5. After inserting the damper into the opening and xing it using the bendable hangers and suitable screws
(3; recommended screw diameter 5,5 - e.g. DIN7981), apply the same re resistive coating (5), at least 2 mm
thick and 100 mm wide, to the opening lling and wall edges evenly from both sides. Do not apply this layer

in the place where the mechanism is located, inspection openings and manufacturer labels.

6. Before the re resistive coating dries, remove the unwanted remnants of the coating.

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

8. Check the damper’s functionality.

Connecting S-SA2 to “multi” Ductwork Made of Boards

The S-SA2 smoke damper can be connected to “multi” ductwork made of calcium silicate boards tested according

to EN 1366-8. If mounted on a duct classied with lower re resistivity, the re resistivity of the S-SA2 smoke damper

will be decreased to the duct level.
This section does not depict duct hanger rules as those are dependent on the weight of the duct itself and must be
statically approved.

IMPORTANT: The interior of the S-SA2 smoke damper must remain accessible for maintenance.
Depending on the installation conguration, it may be necessary to create additional inspection panels
in the connecting ducts.

S-SA2L Installation

S-SA2L

The S-SA2L smoke damper can be installed on “single” (tested according to EN 1366-9) or “multi” (tested according
to EN 1366-9) ductwork. If mounted on a duct classied with lower re resistivity, the re resistivity of the S-SA2L

smoke damper will be decreased to the duct level.

This section does not depict duct hanger rules as those are dependent on the weight of the duct itself and must be
statically approved.

Smoke control dampers can be suspended from solid ceiling slabs using adequately sized threaded rods.

When using anchors in the ceiling, use a re-rated anchor (with suitable a re rating certicate).

IMPORTANT: The suspension of the damper must be loaded only with the weight of the damper.

The connection surfaces must be attened and clean before the re resistive coat is applied.

Suspension systems longer than 1,5 m require re-resistant insulation.

Fixing the S-SA2L Smoke Damper

Each S-SA2L smoke damper has a connection ange with openings in the corners (Fig. 27).
For damper widths greater than 750 mm, another xing point in the middle of the widest side is added and must be

connected as per instructions in

Fig. 28 - Fig. 33.

Operation Manual

After installation, it is necessary to adjust the damper into its operating position “closed”.

In case, that the damper is used for extraction of pollutants, adjust the damper into its operating position “open”.

Connect the actuator to the relevant electric power supply (
The electromotor is activated and adjusts the damper into its operating position.

Fig. 54 - Fig. 61).

Smoke Damper Functionality Check

Switching the damper to the “open” position:

• The blade must come to the fully open position within 60 seconds and must remain locked.

• After reaching the end position of the blade, the appropriate signaling circuit must switch on

– wires S1 and S2 must be connected.

Switching damper to the “closed” position:

• The blade must come up to the fully closed position within 60 seconds and must remain locked.

• After reaching the end position of the blade, the appropriate signaling circuit must switch on

– wires S4 and S6 must be connected.

Smoke Damper Inspection

The actuator keeps the dampers on stand-by during their entire life cycle in accordance with this manual issued by
the manufacturer. It is not permitted to alter the dampers in any way or to perform any changes to their structure
without the manufacturer’s consent.

The operator performs regular checks of the dampers as per established regulations and standards at least once
every 3 months.

The check needs to be performed by an employee who has been specically trained for this purpose by the

manufacturer. The current damper condition evaluated during the inspection must be entered into the
Journal” along with the date of the inspection, the legible name, surname and signature of the employee who
performed the inspection. The Operating Journal includes a copy of the employee’s authorization. If any discrepancies
are discovered, these need to be entered in the Operating Journal along with a proposal for their removal.
The Operating Journal can be found

Immediately after the installation and activation of the damper, it must be checked under the identical conditions

as apply to the above mentioned six-month inspections. On its external side, the damper housing and the actuator

movement are checked. Due to the need to perform a visual check of the damper’s internal parts, it is possible
to dismount the body extension tted with the grille, which will enable access inside the damper or open
the inspection lid if the damper is equipped with one.

The damper’s internal casing, sealings, foaming substance, the damper blade condition and accuracy of its closure
during its leaning against the backstop in the closed position must all be checked. There must not be any strange
objects or a layer of impurities from the air distribution systems inside the damper.
