If you mean broken sirens, there are quite a lot here in the UK. Not many of them ever sound, though.
Right you are, and for some inexplicable reason, the majority of those that don't work properly over here that
are tested happen to be Secomak GP12s. Secomak CS8s are also dodgy, but on average are less so now given that Broadmoor's network is decommissioned.
https://www.youtube.com/watch?v=qlR-pfrcd3s - this is the CS8 at Carstairs Junction. It has
two broken solenoids, so is currently acting as a GP6. It's not even the worst in the nine-siren Carstairs network...
https://www.youtube.com/watch?v=q8k6SvBtK7Y&t=75s - this is the GP12 at Ravenstruther, which is famously even more battered. Motor's star-delta (wind-up phasing) converter doesn't work, the rotors suffer heavily from friction with the stators, and it looks a mess too!
https://www.youtube.com/watch?v=yY-_xe9SmHQ&t=20s - this is the GP12 in Laneham, which is a complete mess (the entire Rampton system is, to be fair). Doesn't have enough power to it, is very loud running up, only runs five "escape" sequences rather than the six it should, etc... East Drayton, one of the other two sins in the network, is very inconsistent in phase conversion but runs well when it does switch, though it suffers from the same radio sync issue as Laneham so ends up very out-of-sync by the end of the "escape" tone. Meanwhile, the GP12 at Woodbeck (the hospital itself) runs perfectly!
These are the ones that I have come across myself - and I have heard them all in person - but I am sure there must be others out there.

No, the Klaxon SS6 is not a Sentry 95...
