damper
5.6.1 General
Smoke control dampers can be suspended from solid
ceiling slabs using adequately sized threaded rods.
Load the suspension system only with the weight of the
smoke control damper.
Ducts must be suspended separately.
Suspension systems longer than 1.5 m require fire-
resistant insulation.
