support brackets (Item No. 3) and any unused hardware.
N OTE : Depending on the personnel and hoist equipment available, the order of remaining steps may

bracket screws, split lock washers, and star washers. (U-bracket not shown.)
4. Secure the horn (Item No. 8) to the bracket assembly (see Figure 4 and Figure 5) using the hardware
from step 3. Repeat the assembly for each horn.

Installation of Three to 12 Horns at Three or More Levels on a Single Pole
The number of Model 12537-001 kits required depends on the mounting configuration selected. For
example:
• Mounting 12 horns at four levels around the perimeter of the pole for 360° of coverage requires six
kits. (See Figure 3.)
• Mounting six horns at three levels for 240° of coverage requires four kits.
• Mounting four horns at four levels for 120° of coverage requires two kits.
1. For each kit being used, assemble the mounting brackets (Item No. 1) and speaker spacer brackets
(Item No. 2) using screws, washers, and nuts (Item Nos. 4 to 7). See Figure 4.
2. On one of the bracket assemblies, attach the support brackets (Item No. 3) using screws, washers, and
nuts (Item Nos. 4 to 7) as shown in Figure 6.
3. Bolt both bracket assemblies together using screws, washers, and nuts (Item Nos. 4 to 7) as shown in
Figure 6. Discard any unused hardware.
4. Repeat steps 2 and 3 for each additional stacked pair of kits to be installed.
5. Mount the bracket assemblies from step 1 to the pole. See Figure 4 and Figure 6.
6. Perform steps 3 through 5 in the “Installation of One to Six Horns” section above.
