To mount the siren on the Class 2 utility pole using the three-foot-long angle iron legs:
1. Uncrate the siren and remove the nuts that hold the siren on the shipping base. In-
stall drivers if needed. Lift the siren approximately 3-1/2 feet with a crane or hoist.
NOTE: To protect the speaker arrays from damage during shipping, all models have
been shipped without drivers installed.
2. If you ordered optional top and side lights, see “Installing Lights on the Siren” on
page 22. You may want to install the lights before placing the siren onto the pole.
3. Install the four legs on the siren mounting plate, as shown in “Figure 2 Siren Leg As-
sembly” on page 15. Use two stainless steel 1/2-inch bolts, nuts, and lock washers
(provided) for each leg. All mounting hardware needed is supplied in the hardware kit
shipped with this manual. Do not tighten the bolts completely.
INSTALLATION PRECAUTIONS: 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.
4. Erect the utility pole according to accepted practices and FEMA guidelines. (Refer to
notice.) Ensure the pole extends at least 40 feet above the ground.
5. Raise the siren to the necessary height and lower it over the pole. Maintain tension
on lifting chain until all bolts are tightened.
6. 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-inch lag bolts, at least 4 inches long,
for each leg. Tighten all bolts, including those from step 2.
Steel Pole Mounting
In a typical steel pole-mounted siren installation, the MOD1004BC, MOD2008BC, and
MOD3012BC sirens are mounted on a Grade A Standard galvanized steel pole. The
MOD4016BC, MOD5020BC, MOD6024BC, MOD6032BC, and MOD8032BC are mounted
on a Grade A Heavy galvanized steel pole. (Ensure that soil loads will conform to this
utility pole size.)
NOTE: The siren leg assembly is not included with the steel/concrete pole models.
To mount the siren on a Grade A Standard galvanized steel pole:
1. Erect the steel utility pole according to accepted practices and FEMA guidelines.
2. Uncrate the siren. Remove and dispose of any hardware that holds the siren on the
shipping base. Install drivers. Lift the siren with a crane or hoist to the necessary
height and lower it over the pole. Maintain tension on the lifting chain until all bolts
are tightened.
3. If you ordered optional top and side lights, see Installing Lights on the Siren. You
should install lights before placing the siren onto the poll.
