S-RA1

S-RA1 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-RA1 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.

• The pressure level is 2 (-1000 Pa ... 300 Pa).

• The casing leakage class C (compliant with EN 1751).

• The blade leakage class 3 (compliant with EN 1751).

S-RA1 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.

• GE1-S-RA1: Extension with Grille for S-RA1

The casing and the blade of the S-RA1 are made of a galvanized sheet metal. A rubber seal prevents leaks of heat or smoke. The casing has connections on two sides with a rubber seal to attach to duct with nominal internal dimension. The dampers actuator of the S-RA1 is always accessible.

The product contains these materials:

• galvanized sheet metal

• rubber

• PE tapes and foil

• galvanized steel fasteners

The manufacturing processes of these materials agree with local regulations. The product does not contain dangerous materials.
