ACA P-15 Tornado Siren Test Milwaukee, WI 9/10/08

Here is the ACA P-15 at Kop's Park in Milwaukee, WI. It's a 15hp 9/12 port siren. This siren is owned by Milwaukee County and is controlled by the Milwaukee County Sheriff's office of Emergency Management. In this video the siren gets tested in Alert mode. The local cicadas, not to be outdone, buzzed back at the siren after the test. I found that sort of funny.

Shot on a Canon Powershot S5-IS.

*UPDATE: It was brought to my attention by a good friend and siren expert that this siren actually has a 15hp motor in it, making it a P-15. You can't tell a P-10 from a P-15 by the shape of the intake cone. The pitch is too high and the wind up is too fast for a P-10. All changes have been made, and credit for this change goes to Archon2561.

P-10s cant come in dau-tone

[RamFett]

@bulldozer950 First, I have no idea what "dau tone" is, you're in your own world on that one. Second, P-10's did come in dual tone. Third, this is a P-15.

The Siren is in ALL CLEAR or NOON WHISTLE Mode, Not Alert mode used.. The only thing the long tone is good for is it alerts you to - its time for lunch!

[RamFett]

@HyperFoxTails That's fine, except that Milwaukee only uses this signal to warn of tornadoes. They do not sound the all clear or sound at noon except for testing

Sounds like an Allertor 125

[RamFett]

That's essentially what it is, just with a different housing.

@HyperFoxTails Taken straight from Wikipedia; "In 1955, the Federal Civil Defense Administration again revised the warning signals, altering them to adapt to deal with concern over nuclear fallout. The new set of signals were the Alert Signal (unchanged) and the Take-Cover Signal (previously the Attack Signal). The All-Clear signal was deleted because leaving a shelter while fallout was present would be hazardous."

does Milwaukee test year round? sweet video, btw.

[kasm279]

@HyperFoxTails Oh? A three minute steady tone meant that nuclear attack was possible.

[HyperFoxTails]

@kasm279 It is a BIG difference, a steady tone NEVER meant DANGER, or Tack Cover.. It meant ALL CLEAR, NOON TONE, Danger is over/or past, or a TEST! Besides a siren will ware out much faster if they keep using the wrong tone..

[jdawg211able]

y do the other sirens gotta sound like silent hill

[kasm279]

@HyperFoxTails Erm, "All clear" isn't a signal anymore. Also, whats the difference?

[tornadodylan]

it has the same wind up as the t-125 XP

[bulldozer950]

@RamFett Oops,Spelling Error.I was told P-10s are only Single.I know this is a P-15
