ACA Hurricane
The ACA Hurricane was an electro-mechanical and rotating-directional, 130dB civilian defense siren, created and produced by Alerting Communicators of America. ACA began manufacturing the Hurricane 130 in 1967, and ceased 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, 1967. They introduced other sirens, however, this utilized new fiber casting techniques, never before used by any other company. It was available in 8/10, 10/12, 8/12 port, or single tone 8, 10, or 12 port configurations, but only 8/10 models were produced. It was meant to compete with Federal Signal's Thunderbolt siren series at the time. The Hurricane started off with a square horn (very similar to the Federal Signal Thunderbolt), but ended with two throats where the horn attaches to the chopper enclosure. Additionally, the Hurricane siren was a supercharged mechanical siren, utilizing a blower and high output chopper similar to the Federal Signal Thunderbolt. 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 high output 130dB siren.
Later on, ACA opted to change the design of the Hurricane to make it stand out from the Thunderbolt siren, and to avoid potential lawsuits over the two similar designs. Aside from that, they decided to correct some design flaws that were discovered in the original model. These changes to the design include: a pole mounted vertical blower, controller removed from blower assembly and housed in its own cabinet, and most notably, the horn changed from rectangular to round. This model was dubbed the "Hurricane 130 MKII" by the company. It also utilizes a 30 horsepower blower motor, as opposed to Federal Signal Thunderbolt's 7.5 horsepower blower motor. The company continued production until 1980, when it was replaced with the Penetrator P-50, a 50 horsepower dual-tone 135 dB siren. All Hurricane 130's are very rare, as most of them have been replaced by newer sirens.
Technical information
| Year | Type | Horn Shape | Rotor/Stator Ratio | Notes |
|---|---|---|---|---|
| 1967 | Hurricane 130 | Square | 10/12 | Cylinder-shaped rotator assembly, with small collector rings. |
| 1970s | Hurricane 130 | Square | 10/12, 8/10, 8/12, 8/8, 10/10, and 12/12 | Larger stationary rotator box, with larger collector rings for better performance. |
| 1973 | Hurricane MKII-130 | Round | 8/10 | This type featured a larger non-stationary rotator box and used a 30 HP compressor, as opposed to an earlier 25 HP compressor. |
| Mid-1970s | Hurricane MKII-130 | Round | 8/10 | Used modified rotator box to allow for easy maintenance. This is the most commonly seen Hurricane of all types. |
| Unknown | Tri-Signal Hurricane 130 (MKII-130) | Round (unconfirmed) | Unknown (Most likely 8/10) | There isn't much evidence that this model exists. However, it utilized solenoids that gave it the third "High-Low" tone. |

MKII-130 |
| Kewaunee, WI | At least 4 were removed and replaced later on. (Kewaunee Nuclear Power Plant) | MKII-130 |
| La Crescent, MN | 3, removed.

The third unit which was located in Kistler Park did not have any type of siren replacement. Before its replacement, the last active two (2) Hurricane MKII-130 units in La Crescent, have no functional rotating mechanism and one of which does not have any functional blower which resulted in a weaker coverage. | MKII-130 |
