Flat Surface Mount
Flat surface mount installation is practical when the installation site is on a flat roofed
building. A weight distribution mat is often required to safely distribute the siren’s weight
on the roof. A Structural Engineer is required to specify the appropriate mounting method
to safely mount the siren on a roof.
Post high sound level warning signs at all roof entry points and be sure that the siren is
not blocked by parapets or other obstructions in the siren’s sound path.
