A siren is typically installed 40 to 50 feet above the ground. If a DSA siren is installed at
less than 40 feet above the ground, the sound intensity at close range may increase, but
at the same time, the effective range of the siren may be reduced. Conversely, if the siren
is located more than 50 feet above the ground, the siren’s effective range may increase,
but the sound may skip over areas closer to the siren. These variables make it desirable
to test the siren’s sound coverage at various heights and locations whenever possible.
Installation Bracket Options
Each DSA speaker array includes a DSAMK1, which is a wall mounting kit for one vertical
stack that contains stainless steel brackets, and mounting hardware. This bracket will
become the lower bracket in your installation. (See Figure 3.) You can use all brackets
on wood, concrete, or metal utility poles. Use brackets on the interior and exterior wall
structures.
Use the following table for bracket options.

Mounting Bracket for Installation
Single DSA
mounted on a
vertical surface
Use a second DSAMK1 bracket. (See Figure 10.)
One to four DSAs
installed on top of
a wood pole with
sirens directed
every 90°
Use any of the following optional upper brackets:
• One DSAMK1 for each DSA.
• One DSAMK4 for installation on the top of the pole.
DSAs installed on
6 inches or larger
pole
Use two DSAMKSPB45 and two I-IP100-PMW for each
DSA. (See Figures 7 and 13.)

for one to four
DSA speakers
• Use DSAMKSP, which includes a complete mounting assembly
for the top of the pole and 4.5-inch pole with brackets for one DSA
speaker.
• Use additional DSAMKSPB45 for each additional DSA.
(See Figure 13.)
4.5 inch steel
pole mount
• Use DSAMKSPB45 for mounting a DSA to a 4.5-inch or larger
steel pole.
• Use one DSAMKSPB45 and two I-IP100-PMW for each DSA2,
DSA4, or DSA6.
• Use an optional I-IP100-PM to provide additional mounting rigidity.
2-3/8 inch steel
pole mount
• Use DSAMKSPB23 for mounting a DSA to a 2-3/8 inch steel pole.
• Use one DSAMKSPB23 and two I-IP100-PM for each DSA2,
DSA4, or DSA6.
• Use an optional I-IP100-PM to provide additional mounting rigidity.
