Ascot Skate Park - The Broadmoor siren hunt of 2018 ends here :(

(reupload - youtube corrupted previous upload) The last siren from our 2018 tour! With the new facility nearing completion it was decided that the old siren network is to be removed. Which ones are still remaining? SEE THIS SIREN SOUNDING (from 2015) HERE:    • More BROADMOOR ESCAPE SIRENS, both with fa...   HOW THEY WORK: The Klaxon CS8 siren. A 415volt 3 phase motor spins two rotors on either side. One rotor is for the high tone and the other for the low tone (the one with most holes is the HIGH tone). During the escape siren, the airflow is cut alternately to each rotor by a shutter on each end producing the distinctive high-low tones. I believe these are known as CODED SHUTTERS - hence the model name Klaxon "CS"8. Both shutters are opened together for the all clear tone. You can just make out the high and low frequencies being produced together if you listen. WHY ARE THERE ESCAPE SIRENS? They were installed in the 1950s/60s with the intention of warning residents in surrounding towns and villages to remain in their homes and keep their children supervised following the escape of a Broadmoor patient. Patients at this hospital are generally dangerous people who need specialist treatment and would be a danger to the public if they were treated in a standard hospital. Some should be in jail but need treatment - their behaviour would be a threat to other inmates. When the hospital was originally built, security at the facility was nothing like it is now and some would say the sirens are no longer needed. But they do a job - "to warn". Escapes can never be "impossible", but "more and more unlikely" as security and procedures improve at the hospital.
