Figure 3-3. Typical Surface-mounted Siren Installation
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 3-3, 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.
