History
The ACA Hurricane 130 was designed by Alerting Communicators of America and presented at a Civil Defense convention in November, 1968. They introduced other sirens, however, this utilized new fiber casting techniques, never before used by any other company. The Hurricane started off with a square horn that ended with two throats where the horn attaches to the chopper enclosure. These were produced until 1973, when a larger, rounded horn was made that was a true exponential horn. The siren was popular with towns looking for a 130dB siren. The corporation continued production until 1980, when it was replaced with the P-50 50 HP siren. All Hurricanes are very rare, as most of them have been replaced by newer sirens. Additionally, the Hurricane siren was a supercharged mechanical siren, utilizing a blower and high output chopper similar to the Federal Signal Thunderbolt.
