Klaxon FP/GP8 30 second alert blast, Manchester, Uk

After a few failed attempts myself & Stag kept trying our best to get a recording of the Klaxon FP/GP8 siren at Valero, Trafford Park.
Sometimes the siren would act up and do just a really short growl or a full 30 second alert blast like you hear in this video. I do apologise about the shaking in the video but I rushed to get my camera out as I got to the site 2 minutes before the test.
I put the siren down as a FP/GP8 as it is at this time unconfirmed on what model Klaxon this siren is and this siren is used as a fire alarm siren which doubles up as a warning siren for the site in case an explosion occurs.
This video can be watched on Stag's channel to so please go and check her channel out for siren related content :-)
