3-3
WARNING
The eyebolt does NOT have sufficient
strength to support the combined
weight of the siren and a utility pole.
Therefore, do NOT attempt to erect
the pole and siren together using the
eyebolt as a lifting point.
3. Erect the utility pole in
accordance with accepted practices
and FEMA guidelines.
4. Raise the siren to the
necessary height, and lower it over the
pole.Maintain tension on lifting chain
until all bolts are tightened.
5. Adjust the legs and
insert shims, if necessary, between the
siren legs and pole. Bolt the siren to
the pole using two user supplied 5/8"
lag bolts, at least four inches long for
each leg. Tighten all bolts, including
those from step 2 above.
C.
Flat Surface Mount.
This installation
configuration is practical when the
installation site is on a flat roofed
building. The siren can be anchored
directly to the roof, on a platform as
shown in figure 3-4, or on a weight
distribution mat like the one shown in
figure 3-5.
This mat is required when
the siren mounting surface is unable
to support over 176 pounds per
square foot (859kg per square meter).
The mat shown in figure 3-5
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 Modulator Series
Siren 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
800 lbs. 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 are left to the
installer. Locate the platform at the
siren installation site. Using suitable
hardware (not supplied), anchor the
platform to the mounting surface.
WARNING
The eyebolt and hoisting bracket do
not have sufficient strength to
support the combined weight of the
siren and the platform. Therefore, do
NOT lift the siren and platform
together using the eyebolt as a lifting
point.
2. Hoist the siren to the
installation site using the eyebolt as a
lifting point (refer to WARNING
above).
3. Anchor the siren to the
mounting surface with a user
supplied 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 user supplied waterproof joints
at the points where the mounting bolts
pass through the roof so that water
does not enter the building.
3-3. SPEAKER CONNECTIONS.
Depending on the model of siren used
the number of speaker connections
and colors will vary. This is due to the
different number of drivers required
for each model. In either case
