SCD-1-W smoke dampers are classified according to PN-EN 12101-2 criteria, with
reference to the following areas:
•
Reliability: double action, Re 1000,
•
Snow load: SL 550
•
Low temperature: T(-25) Wind load: WL 1500
•
Resistance to high temperature: B300
•
The active
area of the dampers with a roof hatch function, with w ≤ 1200
dimension is smaller by 3% than the area of standard version dampers.
•
The active area of the dampers with a roof hatch function, with w > 1200
dimension is equal to the area of standard version dampers.
•
It is possible to make the dampers in the version meeting the requirements of the
BROOF(t1) classification.

OPTIONAL ACCESSORIES
4.8.1. WIND DEFLECTORS
Wind deflectors are to maximize the active area of smoke dampers. They are used
when expected impact of wind would decrease the active area of a smoke damper. These
are profiled elements made of galvanised steel sheet, optimized during aerodynamic tests.
Deflectors are mounted to a damper base with the use of the bolted connection.
