American Signal Corporation
American Signal Corporation (ASC) is an outdoor warning siren and mass notification company in the United States. ASC was founded in 1942 as Biersach and Niedermeyer (B&N). After performing poorly, the company reformed as The Alerting Communicators of America (ACA) in 1967 and expanded the line of warning systems they produced. In 1992, ACA went bankrupt and was bought and reformed as the American Signal Corporation. History The company began as Biersach and Niedermeyer Co. in 1873 as a metal fabricating operation based in Milwaukee, Wisconsin. After the 1941 attack on Pearl Harbor, concerns surfaced that the public should be notified in the event of air attacks. The United States Department of the Army granted the company a contract to manufacture outdoor warning sirens, and in 1942, the company began production of over 2,000 sirens to be installed throughout the Pacific Theater for American troops and Air Bases. The need for these outdoor warnings increased during the follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ACA Cyclone
History The ACA Cyclone was designed by James E. Biersach of Alerting Communicators of America and presented at a Civil Defense convention in November 1968. It was originally rated at 120dB at 100 feet, but was eventually redesigned to the point of reaching 125dB at 100 feet. It utilizes a 40 HP motor (120) or 50 HP motor (125) due to the drag-heavy rotor design. The rotor consists of a "double intake" design, which is believed to have been inspired by Federal's 500 SH-TT siren rotor. The first version, the 1968 Cyclone 120, had both rows of ports angled downwards. Like some of the other 1968 ACA siren designs, it was changed shortly after to improve performance. These improvements included a new, simple intake, and most notably the top row of ports being straightened out, as to direct the low tone outwards for maximum range while projecting the high tone downwards to the immediate area. At some point afterwards we also saw the use of the long, curved intake as seen on their 3 sig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ACA Hurricane
The ACA Hurricane was an electro-mechanical and rotating-directional, 130 dB civil defense siren, created and produced by Alerting Communicators of America ''(ACA)''. ACA began manufacturing the Hurricane 130 in 1968, and began production in 1981. The Hurricane 130 is very similar to the Federal Signal Thunderbolt series and was also meant to compete with the Federal Signal Thunderbolt. History The ACA Hurricane 130 was designed by James E. Biersach of Alerting Communicators of America and presented at a Civil Defense convention in November 1968. They introduced other sirens, however, this utilized new fibreglass casting techniques, never before used by any other company. It was available in dual tone 8/10, 10/12, 8/12 port, or single tone 8, 10, or 12 port configurations, but most models were equipped with an 8/10 chopper port ratio (similar to a Major Third). It was meant to compete with Federal Signal's Thunderbolt siren series at the time. The Hurricane started off with a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
