Fire barrier
Fire barriers are required for busbar elements which pass through fire area.
They are fitted to the busbar element during the manufacturing process.
Comment:
-
After assembling the busbar run, seal the joints in the fire barrier or fire ceiling
with dimensionally stable, non-flammable construction material (Class A1 or
A2-s1; d0 conforming to EN 13501--1) completely to component thickness,
e. g., with concrete or grout. The concrete or grout must meet the applicable
regulations to preserve the fire resistance classification of the wall or ceiling,
e. g., EN 206--1 and EN 998--2.
-
Make sure that, in the case of large wall or ceiling penetrations, e.g., through
reinforcements or steel brackets, the fasteners are secured from slipping out.
