Flat Surface Mounting

This installation configuration is practical when the installation site is on a flat roofed
building. A weight distribution mat is often required to safely distribute the siren's weight
on the roof. A Structural Engineer is required.

Driver Connections

Depending on the model of siren used, the number of driver connections and wire colors
will vary. This is due to the different number of drivers required for each model. See
Figures 6 and 7 for wiring and position.
Observe proper polarity when making these connections:

NOTE: Drivers on all Modulators except MOD1004 and MOD2008 are not assembled
due to shipping orientation.
The bottom module in the speaker array is an inactive module. This means there are
no drivers contained in the module. The next module up is called module number one.
The next one above module one is called module number two, and so forth. These are
referred to as active modules. Each active module contains four (4) drivers except the
MOD6032B has two modules with eight (8) drivers.
