It looks like one of those German 3-port sirens... but the motor seems too small

Definitely a Darley "Helmet". The part between the pole mount and top is a dead giveaway.

Heard, But Not Seen

Thu Jul 20, 2017 1:12 am

I keep hearing this siren near my house, and I am unable to determine what it is or where it's coming from. It goes off at completely random times, usually about once every other day. I'm guessing that it's for some volunteer fire department in my town or a neighboring town, but I've been unable to confirm that. Today, I was fortunate enough to be outside when it went off, so I grabbed my phone and started recording the audio. When I analyze the recording, a few interesting things show up. First, this appears to be a single-tone siren that has a frequency of approximately 470 Hz. But when it spools down, I can see that the steady tone actually persists for a second or two in unison with the spool-down tone, which seems impossible to me. Please see the attached picture of my analysis. Does anybody know what kind of siren this might be? If I know the type, perhaps that will help me to find out where it's located and what it's used for.

Might be a Whelen 2X00.
Seen a: KM Europ, small Klaxon siren and a Gents' of Leicester "ahooga" horn.

Thanks for your help! I'm trying to research the Whelen 2X00, and I can't find that specific model name anywhere (even on Whelen's website). What would Whelen call that particular siren?

The tone that persists in you recording is more than likely reverb from a hill or some other structure that the sound can bounce off of. It could also be coming from another siren in the area, but if it's a small town I doubt it. As far as pitch it's impossible to tell what kind of siren is making the tone. My knee-jerk reaction would be a 508 or Equinox since they commonly run at around that pitch, but tons of other sirens can hit that pitch too from the Model 2 and 5 all the way up to the Tempest series and older Whelens.
