The network of 13 sirens was installed in 1952, following the escape of child murderer John Straffen This siren was accidentally activated during a storm in 2014. Luckily it was the all-clear tone. The siren continued to sound for 2 hours until it was switched off. Surprisingly, there was no pitch drop whatsoever
