Danger due to fire transmission
DANGER Danger to life due to fire trans-
mission if an incorrect connection duct is
used on the APB housing when installed in
the ceiling.
Always use steel folded spiral-seams ducts for
the connection.
DANGER Danger to life due to fire trans-
mission in case of faulty ceiling compound.
It is essential that the remaining gap between the
main duct and the wall or ceiling is completely
sealed with non-flammable materials that are res-
istant to deformation. For example, use concrete
or cement mortar.
