Description
S-SA2L smoke control dampers operate with mechanical or natural smoke and heat extraction systems. They remove
poisonous gases, smoke and fire and can also supply clean air to fire compartments.
S-SA2L dampers have an actuator without a spring. Thus, they have two safety positions: an “open” position and a
“closed” position. Power is necessary for the smoke control dampers.
S-SA2L dampers are designed for on a duct installations ended with grille, not in the wall or ceiling. The “Installation
Methods” section shows the types of installations that are permitted.
Special Properties
• The pressure level is 3 (-1500 Pa … 500 Pa).
• The blade leakage class 3 (compliant with EN 1751).
• The casing leakage class C (compliant with EN 1751).
• The S-SA2L dampers classified “multi” can also operate in compartments that are identified as "single”.
• AA – automatic activation (sets the safety position within 60 seconds). No thermal insulation around the actuator
needed.
Fire Resistivity
S-SA2L smoke control dampers have a CE certification that meets the EU’s Construction Products Regulation and
complies with standard EN 12101-8:2011. EN 1366-10:2011, A1:2017, and EN 1366-2:2015 are the reference
standards for the tests. EN 13501-4:2016 is the reference standard for product Classification. The smoke control
damper and its installation counts as one unit for fire resistivity rating:
• Damper installed on a duct with horizontaly oriented damper blade in closed possition:
EI 120 (hod - i↔o) S1500Cmod AAmulti
• Damper installed on a duct with vertically oriented damper blade in closed possition:
EI 120 (ved - i↔o) S1500Cmod AAmulti
Types of Activation

• K1-S-SA2L: Kit for Sheet-Metal Duct Installation.
• LEAS: Damper Extension for Thick-wall Installations.
Design
The casing of the S-SA2L is made of a galvanized sheet metal. Blades are made from calcium silicate boards. A foam
seal, silicone rubber gasket with an intumescent seal prevent leaks of heat or smoke. The casing has flange on one
side with holes for screws to attach to sheet-metal duct flanges. Casing is fitted with grille at one side. The casing also
has a calcium silicate board circumfering the blade area for connection to board made duct. The damper casing has
inspection openings. The mechanisms actuator of the S-SA2L is accesible from the outside.
Composition of Materials
The product contains these materials:
• Galvanized sheet metal
• Calcium silicate board
• Fireproof carbon fiberglass
• Polyurethane foam
• Intumescent strips
• Bound silicone in extruded gasket
• Ethylene-propylene rubber
• PE tapes and foil
• Galvanized steel fasteners
• Acrylic sealant
The manufacturing processes of these materials agree with local regulations. The product does not contain dangerous
materials. No silicone caulks are used in the manufacturing processes.

Diagrams
The pressure drop, and A-weighted total discharged sound power level depend on the nominal width and height of the
damper and air flow volume at different duct pressures. The type of activation does not influence the airflow
parameter, therefore only one activation type is shown in the diagrams.

Product Handling
Warning
Some damper parts can have sharp edges. To prevent injuries, use gloves when you install or move the damper. If
you use or operate the damper incorrectly, there is a risk of:
- electric shock.
- fire.
- other damage.
Ensure that installation is performed by a trained person. The S-SA2L is made of boards and sheet metal. Thus
considered fragile.Be careful when you move the smoke control damper. Two persons are necessary to move the
dampers and put them onto the duct and/or hangers.It is necessary to move the bigger dampers with suitable lifting
equipment (forklift, crane).Please follow both textual and graphic instructions.
1. Unpacking:
• Remove the packaging
2. Functionality check:
• Perform damper's functionality check (see "Operation Manual" section).
3. Placing the damper:
• Prepare the duct connection surfaces as per the desired installation type.
• Prepare the corner screws in the board duct connections.
• Fix the supports to the propper place as per chosen installation type.
• Carefully lift the smoke control damper with the forklift, crane or manually.
• Place the damper on the hangers and on duct connection surfaces.
4. Fixing the damper:
NOTE: Make sure to continually check the alignment of the damper against the duct connection when performing the
next steps.
• Prepare the installation brace when installing to board ducts.
• Fix the damper with duct by using suitable screws through the flange corners and installation brace.
• Verify there is no skewing of the damper body by measuring diagonal dimensions of the blade area or the nominal
dimension.
• As per chosen installation finish the connection surfaces with suitable caulck and overlapping boards.
5. Finishing:
• Clean the damper from the debris and excess material from the filling or insulation.
• Connect the dampers actuator as per activation type wiring diagram in the "electrical connection" section.
• Perform damper's functionality check (see "Operation Manual" section).
• Create and/or fill out the Operating Journal included with the smoke control damper (Operating Journal can be also
downloaded at design.systemair.com)

Installation Methods
Warning
• Suspension systems longer than 1,5 m require fire-resistant insulation.
• Obey the applicable regulations and standards of the country that this product will be installed in.
• Make sure that only approved personnel performs the installation.
• Obey the written instructions and the illustrations in selected installation method.
Installation Rules
• 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 classified with lower fire resistivity, the fire resistivity of the S-SA2L
smoke damper will be decreased to the duct level.
• The duct connected to the smoke control 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.
• Smoke control dampers can be suspended from solid ceiling slabs using adequately sized threaded rods. When using
anchors in the ceiling, use a fire-rated anchor (with suitable a fire rating certificate).
• Easy access to mechanism and internal parts during inspection must be considered during damper placement.
• The minimum distance between the smoke control damper bodies must be 200 mm (refer to Standard EN 1366-2).
• The minimum distance between the smoke control damper and the adjacent wall or ceiling must be 75 mm.
• If the grilles are not original accessories, there must be a minimum clearance between the damper blade in its open
position and self-standing grille. The clearance between the damper blade and these components must be at least
200 mm (refer to EN 1366-10).
• Lists of all permitted installation methods are provided in Handbook.

Installation L1H
Horizontally Oriented Damper, Connected to Duct With Ledge
1. Prepare the duct connection and the damper hangers. The opening dimensions must be created according to the
details of each type and thickness of the connected duct.
NOTE: The dimensions of the openings are the result of the nominal dimensions of the damper with added clearance.
The dimensions of the connection will be W1 and H1.
a. Clean the connection surfaces. Make sure that the surfaces are even.
2. Apply a fire resistive coat (F1) to the connection surfaces.
CAUTION: The product label must remain clean and readable.
3. Obey the procedure in the “Product Handling” section to put the damper on its suspension system and against the
connection surfaces.
CAUTION: Make sure the kombi screws are fixed to the board duct corners. If the width of the damper is more than
800 mm, use installation brace during the installation procedure.
4. Connect the damper’s flange (on the blade side) to the duct.
5. From boards (F2, F3) create a collar overlapping the connection.
6. Fix the overlapping collar to the damper with screws (F4). Fix the collar to the duct by using screws as per
instructions of duct system manufacturer.
7. Perform damper's functionality check (see "Operation Manual" section).
IMPORTANT
• The suspension of the damper must be loaded only with the weight of the damper.
• Suspension rods longer than 1,5 m require fire-resistant insulation.
• The fire resistivity of the S-SA2L smoke damper must be decreased to the duct system performance.
• The maximum resistivity for L1V installation is EI120S with pressure level 3 (-1500 Pa … 500 Pa).
