TempestTM Sirens

 

The Tempest™ series of electro-mechanical sirens from American Signal Corporation cover four models from the Tempest-112 to the Tempest 135 AC/DC. This product line has its origins dating back to World War II in the wake of Pearl Harbor. ASC sirens were utilised to warn thousands of US servicemen and women, support personnel, and civilians.

 

Since the end of the war, tens of thousands of Tempest sirens have been deployed in all states of the US, and in 60 countries around the world. Installed across a broad range of military and government facilities, industries, and communities to provide mass notification to tens of millions of people, these are proven and respected sirens. The sirens in this series are omni-directional producing 3600 sound coverage of a number of selected warning tones only.
