Systemair S-RA1 - Smoke Control Damper

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. Special Properties • 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). Fire Resistivity 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. Resistivity rating for damper installed on the duct: E600 120 (ve...
