As I understand it, the 550AT was designed to compete with the HOR Super Sirex, which would make sense.

I'm guessing it's a ten-horsepower motor, as the siren looks about the size of a 2T22 in power.

It does look just like a horizontal 2t22 with reflectors rather than cones.

I checked my mom's calendar that the town gives her (she's a councilwoman) and it noted the test as Friday, May 1 7:00 PM (weather permitting)
Still close enough to a Fed Sig 550AT to drive out on test day: First Friday in May - 7PM!

Thank you.
Come down Colorado route 83. Then, catch 86 East in Elizabeth. Then, a mile short of entering Kiowa, right on Elbert road. It's 26 miles south to US Highway 24. Then, it's 12.5 miles east/northeast to Calhan.
If you're using Google Maps, City hall is at 556 Colorado Ave Calhan, CO 80808.

Can anybody please e-mail me info and pictures of this siren to [email protected] ? I'm researching this siren in my spare time and could use the help.

Kudos. The only sirens (IMHO) that are really any good are the Modulators, Model 2's and Eclipse-8's.

The 2001-DC was the best 2001 model ever made, I wish Federal would begin making that model again. The 2001-SRNB's and above are way too high pitched.

I wonder, did the SD*10 come into the scene before this or did this come after the SD*10?
