This BEATS THEM ALL - I've filmed lots of sirens from the Broadmoor system, but this one.... I'm almost speechless! So it's probably easier if you just watch the video (oh.... and it would certainly help if you have an interest with old sirens!)
..........
BTW, the pronouciation of "RAV-EN-STRU-THER" - nope!!! According to youtube user 'cgiof3ln' it's pronounced "Renstree" or "Reinstree". ...I mean, that would have been my second guess!? (sarcasm!)

@residentelect 5 лет назад

Now then Matt, my siren knowledge is not quite what it should be! With that in mind, may I ask a question? These sirens are tested at regular intervals, but apart from yourself I don't see any other individuals or engineers/personnel monitoring the actual output of the siren...? Is all the testing done remotely via telecoms, or do they rely on information from locals to let them know the siren is working as it should? Judging by the state of this grand old specimen, I can't imagine an engineer has been present during testing for many a year?!

@ajs2120 5 лет назад

Wow, is all I can say to that! Judging by the clunks from the control box as it starts, I would say it must be on a star/delta starter, which is taking too long to switch over from star to delta, hence the sudden increase to the full speed at 50Hz. The noise is of that siren is simply unmatched from any others I've heard.

@brintheboxer4020 4 года назад

0:20 how did you get that map?

@ArlenMoulton2 3 года назад

In my opinion, the reason why it changes speed *could* be due to star-delta starting of the motor. Being a much bigger and more powerful siren than the CS8, it could need to start itself in star mode to have enough torque, then switch to delta to get higher speed. Either this or rather than having shutters like the CS8, this model switches speed to change tone, either way it's definitely some kind of electrical change rather than mechanical.

@Nthuziast 2 года назад

the way a siren works is by forcing air out of a specifically sized hole at a fast speed. the closer the rotor is to the stator, the more air is forces through the ports, and the louder the siren is. seeing how the rotors are literally clipping the stator, it makes sense the ground is shaking. also, how ironic, the newer siren is in worse condition than an older siren! like, a lot of them.

Hi. If this is the Crowthorne Statio siren you are referring to then unfortunately I don't think it works anymore. Someone went to film it about 1 to 2 months ago and it didn't sound. The only one that I know still works is the main hospital one. All the rest that remain are unknown, but I think gone are the times where you can go and film these and expect them to work.

The motor is going from star to delta. The timing of the contactors is a bit out. Normally full speed happens at about 4 to 6 seconds after start up. The three phase motor windings are basically switched between 230 and 400 Volts on the motor windings, hence increase in speed as the torque is improved.
