Recent development of a new 180 horsepower Chrysler Industrial V-8 Engine enabled Chrysler engineers to produce power for a 3-stage compressor.  Increased pressure from this compressor drives air through 6 giant horns at 400 miles per hour, producing a sound of approximately 173 decibels!  This warning can be clearly recognized over a diameter of 3 miles under normal conditions.

It is designed to fill the pressing need for a positive signaling device for City and Industrial air raid warning.  Because it has self-contained power it is independent of vulnerable central power systems. 

One, or any number Sirens may be remote controlled from a central control station if desired.  They may be operated without personnel being on or near them.  When in operation, the Siren makes one complete revolution every minute.

These Sirens are available only for Defense Warning Systems.  They may be purchased by Cities and Towns, Defense Plants, Airports, Military Installations and other vital areas needing air raid protection.
