Wooden Pole Mounting
A typical wooden pole-mounted siren installation is shown in Figure 3. The siren
is mounted on a Class 2 utility pole (ANSI type wooden pole or equivalent) with a
minimum horizontal ground stress rating of 3,700 pounds (1678 kg). Ensure that soil
loads will conform to this size utility pole. It is attached to the pole by means of legs, as
shown in Figure 2.
