Tempest™-121 Siren
The Tempest™-121 Siren is one of the latest products of American Signal’s electro-mechanical siren series. This product line was launched during World War II in the wake of Pearl Harbor. Thousands of ASC sirens warned hundreds of thousands of US combatants, support personnel, and civilians living in the Pacific theatre. Since the end of the war, tens of thousands of Tempest sirens have been deployed in all 50 states, and 60 countries across a broad range of military and government facilities, industries, and communities to provide mass notification to tens of millions of people. This siren is omni-directional with a 360 degree sound coverage pattern. The T-121 is a tone only siren and is used to warn communities for all kinds of natural and manmade disasters.
The Tempest™ 121 siren is robust, dependable, low maintenance, and a cost effective system.
