S-BA2

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.

• 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).

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:

• Damper installed within a wall: EI 90 (vew - i↔o) S1000Cmod AAmulti

• Damper installed on the duct: EI 120 (ved - hod - i↔o) S1000Cmod AAmulti

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.

• 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.

• B24-W - Smoke control damper with an activation mechanism with a Belimo actuator (24V AC/DC) and auxiliary switches, with provided cable connectors for the supply and communication unit (communication unit not part of the mechanism).

• B24-SR - Smoke control damper with an activation mechanism with a modulating Belimo actuator (24V AC/DC; 0(2) V...10 V DC) and auxiliary switches. Modulating actuators have the possibility to open the blade at a desired angle.

• BST0 - Smoke control damper with an activation mechanism with a Belimo actuator (AC/DC 24 V, supply through communication unit: AC 230 V) and with a Belimo supply and communication unit BKNE230-24 (other communication units on demand).

• BST1 - Smoke control damper with an activation mechanism with a Belimo actuator (AC/DC 24 V), with supply and communication unit (SLC powered) BC24-G2 (THC).

• BST10 - Smoke control damper with an activation mechanism with a Belimo actuator (AC/DC 24 V), with supply and communication unit (AC 230 V) BKNE230-24-PL (Powerline).

Other communication units are possible on demand.

The casing of the S-BA2 is made of a galvanized sheet metal. Blades and mechanism access doors are made from calcium silicate boards. A foam seal with an intumescent seal that prevents leaks of heat or smoke. The casing has flanges on two sides with a thread to attach to sheet-metal duct flanges. Two sides of the damper have inserts with a thread to attach the grille. The damper casing and two covers on two sides give protection to the mechanism and the actuator of the S-BA2. They also give access for easy connection.

The product contains these materials:
