To alert any of these U. S. Cities would require NOT MORE THAN 5* CHRYSLER SIRENS

According to the most recent official census figures, these twenty-four cities have populations ranging from 70,000 to 85,000.  One of them has an area of twenty square miles, or about 3500 people per square mile, while another has only slightly more than five square miles with 13,760 people per square mile.  But despite their apparently widespread differences, none of these cities would require more than five Chrysler Sirens.  This number would give each of them good basic protection and a warning system second to none.

The Chrysler Siren is ideal for the small city as well as the large.  First, because it has its own power plant, the Chrysler Siren can be operated from virtually any fixed or moving site.  Second, the Chrysler Siren functions both automatically and manually, enabling combined utility remote-controlled operation with neighboring communities as well as individual, manual operation for purely local use.  Finally, the 180 horsepower Chrysler V-8 Industrial Engine develops a terrific 400 miles per hour blast, sufficient to send the "loudest warning ever heard" for miles in every direction from the rotating siren. 

No other warning device compares for power, for mobility and - because of its tremendous coverage - for economy.  Help arrange a demonstration of the Chrysler Siren in your community, write: Dept 24, Siren Layout Service, Industrial Engine Division,  Chrysler Corp., Trenton, Michigan.

CHRYSLER AIR RAID SIREN
