III. INSTALLATION.
IMPORTANT
Before proceeding, read and understand the
SAFETY NOTICES on pages
i
and
ii
of this
instruction
sheet.
A. General.
During installation and before operation of all units,
steps 1, 2, and 3 must be performed.
1. In order to control the rotation of the Speaker
Array, it is necessary to connect the wht/red wire from the
speaker array to JP25-1 on the motherboard (see figure 2).
CAUTION
To prevent damage to rotator assembly, steps
2 and 3 must be completed prior to operating
the unit.
2. Remove the bottom rear panel of the Speaker
Array. In some units, wooden blocks may be installed
between the roller brackets (see figure 3). If installed,
remove the wooden blocks from the roller brackets. The
rollers should be adjusted for minimal clearance to the pole
(approximately 1/32-inch).
3. Remove the second rear panel from the top of
the Speaker Array. Remove the pipe plug from the upper
tapped hole in the rotator gear box and replace with the
supplied vent plug (see figure 4).
4.
Speaker
Array
Positioning.
The Home Switch Assembly is located on top
of the commutator rings. It allows the Speaker Array to be
positioned in one of four zones. The switch assembly is
factory set to align the Speaker Array with an arrow on the
Speaker Array base plate indicating Zone 1 (Home or
North).
If Home Switch Assembly adjustment is necessary,
it may be performed now or after Pole Mounting
Figure 2. Motherboard Relay Connection
Figure 3. Wooden Block Removal
or Flat Surface Mounting is completed. Refer to paragraph
III.D. for a description of the adjustment procedure.
5. Replace both panels.
B.
Pole Mount.
A typical pole mounted installation is shown in
figure 5. To provide optimum signalling effectiveness, the
siren must be mounted in accordance with FEMA standards.
Use a utility pole (ANSI Type 2 wooden pole or equivalent)
with a minimum horizontal ground stress rating of 3,700
pounds (1682kg).
The siren is attached to the pole by means of a
stand provided by Federal. The stand consists of four legs
which must be connected to the base plate. The base plate
serves as a vertical support for the Speaker Array while
adding rigidity to the stand. To install the Speaker Array on
a Class 2 utility pole, proceed as follows:
1. Install the Class 2 utility pole in accordance
with accepted standards and practices.
2.
Federal recommends that the 50-foot (15.2m.)
interconnecting cable be routed through user-supplied
conduit to the Control Unit. The bottom of the junction box
is equipped with a hole to accommodate a 1" weatherproof
conduit fitting.
