Pressure level 3 (-1500 Pa … 500 Pa)
Leakage class 3C as standard
The S-SA2 smoke control damper can be used in compartments classified as multi as well as those classified as single.
The S-SA2 smoke dampers are designed for mechanical or natural smoke and heat extraction systems.
To facilitate the installation, the S-SA2 body is fitted with single or multiple bendable brackets. They are positioned depending on the casing size and weight which simplifies the installation process and reduces the time and number of people needed.
The S-SA2 provides effective protection against smoke, fire and toxic gases when used in both mechanical and natural heat extraction systems.
To enhance the safety, it’s also able to provide a supply of fresh air to fire compartments. The S-SA2 smoke dampers are fitted with an actuator without a spring. This means they have both an open and closed safety position and require power even in the event of a fire.
The S-SA2 casing is manufactured from galvanized sheet steel. The damper blade is manufactured from calcium silicate boards. The damper outer frame contains active intumescent seal to avoid the spread of hazardous smoke and heat. Damper casing flanges are constructed for the connection of the damper to the continuous duct.

##AT Text for Systemair – smoke extraction damper S-SA2 / S-SA2LSquare, maintenance-free smoke extraction damper Multi S-SA2 / S-SA2L with dimensions ranging from W x H 200 x 200 to 1600 x 1000 mm; made of galvanized sheet steel. The housing is constructed from galvanized sheet steel. The butterfly disc is composed of abrasion-resistant, asbestos-free calcium silicate. It includes a rubber seal and an intumescent seal that expands in the event of a fire. Fire rated for up to 120 minutes. S-SA2 is suitable for dry and wet installations in solid walls and ceilings, lightweight walls, as well as in firewalls. S-SA2L can be installed outside of walls on and in ventilation ducts featuring both horizontal and vertical butterfly disc axes. Complies with the European product standard DIN EN 12101-8 Fire protection tested according to DIN EN 1366-10 Classification according to EN 13501-4 AA-Automatic Activation moves to the open or closed position within 60 seconds. Manufacturer’s declaration of performance All smoke extraction dampers are DIN EN 1751-rated at air-tightness class 3/C (for damper/housing). Very short face-to-face dimensions of 300 mm With assembly aid for fixing the smoke extraction damper during installation Narrow damper blade, resulting in excellent physical and acoustic properties.The actuator consists of either:– a reversible 24 or 230 V motor– Optionally also available with bus module.Type: S-SA2 – installation in ceiling/wallType: S-SA2L – Installation in ventilation duct– B230 = Version with 230 V Belimo motor– B24 = Version with 24 V Belimo motor– BST- = Version with 24 V Belimo motor and Belimo bus module 230/24– G230 = Version with 230 V Gruner motor– G24 = Version with 24 V Gruner motor– GST = Version with 24 V Gruner motor and Gruner bus module 230/24Other accessories:o D1-S-S-SA2 = Air duct extension with end grilleo K1-SS-SA2L = Kit assembly for sheet metal duct installation - Width: 200- Height: 200- Activation Type: B24 (AC/DC 24 V Belimo Actuator)- Airflow direction: Extract- Installation method: Not selected (Overview in installation tab)- Accessories: Not selected
