SOUND REDUCTION HAZARD: Connecting driver wires out of phase may cause
severe reduction in sound output, which may result in serious injury or death.
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 utility pole size. It is attached to the pole using legs, as shown in Figure 2.
