ACA Hurricane

The Hurricane 130 is similar to the Thunderbolt siren by Federal Signal Corporation and was also popular with towns looking for a high output 130dB siren The Hurricane 130 was designed by James E. Biersach of Alerting Communicators of America (ACA) and was presented at a Civil Defense convention in November 1968.

It was meant to compete with Federal Signal's Thunderbolt siren series at the time.

The Hurricane came off with a square horn (similar to the design of the Thunderbolt siren), with the exception of having two throats separately attached to the chopper enclosure.

The original Hurricane 130 came with a unique all-in-one chopper and motor assembly with a direct-drive air compressor with a 25-horsepower motor ACA later revised the design of the Hurricane 130 to differentiate it from the Thunderbolt siren and to also avoid any potential lawsuits over the two similar designs.

These changes to the design include a pole-mounted vertical compressor, with the controller removed from compressor assembly and housed in its own separate enclosure and a redesigned chopper assembly for easy maintenance.
