Figure 3-2. Siren Leg Assembly.
Using the 3 ft. long angle iron legs, the
siren is mounted on the Class 2 utility pole as
follows:
1. Uncrate the siren and remove the
nuts that hold the siren on the shipping base.
Lift the siren approximately 3-1/2 ft. with a
crane or hoist.
2. Install the four legs on the siren
mounting plate, as shown in Figure 3-2 . Use
two 1/2" bolts, nuts and lockwashers
(provided) for each leg. Do not tighten the
bolts completely.
WARNING
The lifting bracket 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 bracket as a
lifting point.
3. Erect the utility pole in accordance
with accepted practices. Be sure the pole
extends at least 40 ft. above the ground
(refer to WARNING above).
4. Raise the siren to the necessary
height, and lower it over the pole.
5. Adjust the legs and insert shims, if
necessary, between the siren legs and pole.
The legs adjust to a diameter between 7.53”
and 12.25” (See
Figure 3-3 ). Bolt the siren to
the pole using two 5/8" galvanized lag bolts
with washers and split lockwashers per leg.
At least four inches of lag bolt must be
screwed into the pole. Tighten all bolts.

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
