S-BM2

Smoke control dampers are designed for mechanical or natural smoke and heat extract systems. Its function is to extract toxic gases, smoke and fire or provide a supply of fresh air to fire compartments. Smoke control dampers are fitted with an actuator without a spring; therefore, they have two safety positions, “open” and “closed” and require power even in the event of fire. S-BM2 smoke control damper is designed for the installations listed in the “Installation Methods” section of its Handbook.

• Battery installation of up to 4 dampers

• MA – manual intervention (can be used also as an AA classified smoke control damper)

The safety position can be adjusted up to first 25 minutes during smoke extraction

• Multi - usage in compartments classified as "multi"

Can be used also in compartments classified as "single"

• Pressure level 2 (-1000 Pa ... 300 Pa)

• Casing leakage according to EN 1751, class C

• Blade leakage according to EN 1751, class 3

• Exceptional free area and low pressure drop

• Installed into walls or ducts

S-BM2 Smoke control dampers are CE certified following the Construction Products Regulation according to EN 12101-8:2011. Tested according to EN 1366-10:2011 + A1:2017, EN 1366-2:2015 and classified according to EN 13501-4:2016. The smoke control damper together with its installation form an inseparable part of the fire resistivity rating.

• Damper with horizontally oriented blades: EI120(vew - ved - hod - how - i↔o)S1000CmodHOT400/30MAmulti

• Damper with vertically oriented blades: EI90(vew i↔o)S1000CmodMAmulti

Depending on the S-BM2 installation assembly this damper has two main product types:

• Standalone installation - grille types 00, 01, 02, 11, 22

• Battery installation - grille types M0, M1

• 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) BKN230-24-PL (Powerline).

Other communication units are possible on demand.

• K1-S-BM2: Cover boards for in-duct installation.

• H1-S-BM2: Hanger for horizontal damper mounting.

S-BM2 has a casing and blades made from calcium silicate board. The closed damper is sealed by silicate wool sealing to avoid the spread of heat and smoke. Front board surfaces are fitted with threaded inserts for sheet metal duct flanges. If the damper is ordered with grille, both sides are fitted with threaded inserts for grille placement. S-BM2 has mechanism and actuator enclosed by the dampers casing and two covers on each side for easy access and connection.

The product contains galvanized sheet metal, calcium silicate board, fireproof carbon fiberglass, polyurethane foam and alkaline earth silicate wool. These are processed in accordance with local regulations. The product contains no hazardous substances.

S-BM2 smoke control damper standardly have class C casing tightness and class 3 blade tightness according to EN 1751.
