Hey,

Do you know which siren that is? As far as I know, it's mostly used by the west midlands police. I spent quite a lot of time searching for the name of the siren but I didn't get any results. 

 

The siren is quite always on their unmarked bmw vehicles. 

 

Here's a video:

Most likely a Whelen Alpha Series 12R.

Hmm I'm pretty sure it is not. It is probably a siren of the Whelen Alpha Series but not the 12R. Or maybe just a newer version??

 

It is   wail --> yelp --> hi-lo --> and then priority

the 12r is priority and then hi-lo

 

Also the wail us much faster. And priority sounds different too. 

 

at 2:50 there's another good example. 

 

and this one too

 

I think the sirens mentioned in this trend are either a Standby RSG MCS 32 or a Standby RSG CVS...

All the tones are not very "Whelen" like and the frequency of the Hilo just wouldn't be tones that generates from a Whelen siren system.

 

Yes, I think so too. No matter what siren from rsg standby it is, there are no demos of it. At least I couldn't find the ones I was looking for. I created a siren by myself, using responding compilations vids. But thanks for your help 🙂

Glad you've made one yourself however just so you know that is the RSG MCS32, which is the most common used police siren around United Kingdom and are most popular to be known in londonn and Obviously Birmingham like you qutoed

As the Metropolitan Police quoted,
