BROADMOOR ESCAPE SIRENS working perfectly!! {{Beware: LOUD VIDEO!}}

Here we have two sirens recorded on different days. Both activate at 10am on a Monday. I've added a 30 second off-set (see each siren's actual time on the bottom left/bottom right). It's much better to illustrate in the video like this, else they would both be starting up at the same time. Recording them with a 30 second off-set allows you to see each stage, one siren at a time. Both sirens in this video are working perfectly. Most of the other ones either don't work at all (during my visits) or have a fault with one of the shutters - either one is jammed open or shut. \/\/\    • SIRENS - Finding the 13 Broadmoor sir...   (this video is SIREN H and SIREN I) /\/\/ ABOUT THE SIRENS: Here are two sirens from a system containing 13. They are located in the neighbouring towns surrounding a secure hospital in the UK. Me and Chay went out to find them all - this is now complete. See all my other videos here:    • SIRENS - Finding the 13 Broadmoor sir...  ) It was a very interesting bank holiday Monday lol! Chay was a bit apprehensive while waiting for the first siren to sound, but loved it afterwards :) He liked it enough to stay with me whilst tracked them all down. It was a good day as we did other things like play football in the parks, McDonalds and see the sirens of course! It was a mixed bag - some viewable from the street, some hidden so much that you'd never know they were there (unless it went off!), some in council depots, compounds, parks and believe it or not - in the middle of housing estates metres from houses! (would scare the living daylights out of residents if they went off at 3am!) Some are in secure places with no access at all. The sirens are tested at 10am each Monday. I have recorded most of them in action (lots of Monday's@10am!) - in this video there are two of them. BY THE WAY - In reality all 13 sirens are tested together, but so that you can see each stage (start-up, running, running-down) of each siren, I have offset the sirens by about 30 seconds (see the times in the bottom left and right in the video). 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.
