sounded like a 2001 when it started up but thats a rare combination for a p10/15

@piper102206 That's right. Allertors from 1968 to around 1971 used this rotator design. The 8-12 port was only made in 1970, so that is probably when this siren was originally installed. No idea when it was converted to the Penetrator horn, but these older Allertors were 10 HP.

@JustInn014 The motor houseing is aa little taller and more slender like the old allertors, this must be one of the earliest makes of this siren.

Another suburb did this with their Allertors as well. I wanna say Orland park but I could be wrong. nice video. sounds awesome!

@garyhstorms10 The allertor and the penetrator are the same damn siren, just one has that funky horn.

Sounds like the Penetrator horn doesn't have quite as low of a cutoff frequency as the Allertor horn. The only reason I can think of for them swapping out the horn and intake like they did on this one is because the old horn and intake probably got damaged. I personally like the Allertor's lower cutoff freq better, but this is still a great video.

@garyhstorms10 This thing definitely used to be an old Allertor, because it has the old Allertor motor in it. It would sound about 3/4 of a semitone higher in pitch if it had a Penetrator motor in it.

That's a unique pitch combination! NEVER heard anything like that before!
