Figure 3-1. Mounting Plate Drilling Detail
(d) Lay the siren mechanism on its side and attach the three legs to the mounting plate using three
angle iron clips and six 1/2"-13 nuts and bolts. Attach the legs through three .75" X 1” slotted holes
indicated in figure 3-1.
(e) Dig the hole for the
Class 2 utility pole and lay the pole on the ground as close as practical to
the installation site.
(f) With the siren laying on its side, and the pole laying on the work surface attach
the siren to the
utility pole using at least two
5/ 8" lag bolts at least four inches long (not supplied) for each leg. If
necessary, install shims between the siren legs and the pole.
(g) Wrap a cable or chain capable of bearing at least one ton around the pole-siren combination at
least three times. Wrap the chain or cable around the legs of the siren. Use the chain or cable in
conjunction with a crane or hoist capable of lifting at least one ton to erect the pole in accordance
with accepted practice.
(h) Install the Model RC2W Motor Starter and a fused disconnect switch in a location on the pole
that is readily accessible to service personnel, but discourages vandalism. The RC2W must be
installed in a vertical position for proper operation. Install the electrical devices following NEC
recommendations and local electrical codes. A suggested installation configuration is shown in
figure 3-2.
