distributes the siren weight to approximately
25 pounds per square foot (122kg per square
meter). When installing the siren on a flat
roof, be sure that it clears the parapets or
other obstructions by at least ten feet.
To install a 2001-130 on a flat roof or other
flat surface, proceed as follows:
1. If desired, construct a platform for
mounting the siren, which must be capable of
supporting at least 435 lbs. (197kg.) as well
as withstanding a siren wind load of 100
mph. The platform must also be capable of
distributing its own weight plus the siren to a
value that is safe for the mounting surface.
Platform design and construction details
should be designed by a structural engineer
familiar with the building construction of the
intended install location. Locate the platform
at the siren installation site. The platform
must be properly anchored to the mounting
surface.
WARNING
The hoisting bracket does not have
sufficient strength to support the
combined weight of the siren and a
platform. Therefore, do NOT lift the
siren and platform together using
the bracket as a lifting point.
2. Hoist the siren to the installation site
using the lift bracket as a lifting point (refer to
WARNING above).
3. Anchor the siren to the mounting
surface with 1/2" lag bolts or nuts and bolts,
as appropriate through the mounting holes
(one in each corner) in the siren base plate
(see
Figure 3-4 , detail A). If the siren is
mounted directly on a roof, (without a
platform or weight distribution mat) be sure to
install waterproof joints at the points where
the mounting bolts pass through the roof so
that water does not enter the building.
