S-BA2
Description
S-BA2 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-BA2 dampers have an actuator without a spring. Thus, they have two safety positions: an “open” position and a
“closed” one. Power is necessary for the smoke control dampers.
The “Installation Methods” section shows the types of installations that are permitted.
Special Properties
• Body length only 145 mm and no blade overhangs.
• You can install the smoke control damper into walls or on ducts.
• The S-BA2 dampers classified “multi” can also operate in compartments that are identified as "single”.
• The pressure level is 2 (-1000 Pa ... 300 Pa).
• The casing leakage class C (complient with EN 1751).
Fire Resistivity
S-BA2 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 the Classification. The smoke control damper
and its installation counts as one unit for fire resistivity rating:

Types of Product
There are different types of S-BA2 connection. Thus, there are several types of grilles:
•
00
– without grille.
•
01, 02
– with grille on one side only.
•
11, 22
– with grille on both sides.
Types of Activation
•
B230
- Smoke control damper with an activation mechanism with a Belimo actuator (230V AC) and auxiliary
switches.
•
B24
- Smoke control damper with an activation mechanism with a Belimo actuator (24V AC/DC) and auxiliary
switches.
