News: The modern name of Kent is derived from the Brythonic word kantos meaning "rim" or "border", or possibly from a homonymous word kanto "horn, hook"

A friend of mine had one in his house where he lived at Redruth, Cornwall.
He had been approached by the powers that be to see if he would be willing to have one installed in in house.  The previous person in the village could no longer accomodate, so my mate said yes.

He said one reason why they approached was because his brother worked at the MOD in London.
And I seem to remeber him saying that they worked off the telephone line.

He also said that once a week I think Thursday(?), a voice would call up to test it, and he would telephone a number to tell them it was working OK.  That was all he had to do.  I did ask him what would happen if it went off for real, and he told me at the time that he wasn't allowed to talk about it too much. This would have been late 1980's time.  Then they just came along and took it out and that was that.

Very nice find!  I wonder how many of these still exist in various places?

I seem to remember we had something similar in the receptionists office at GG Baxters meat factory in Sarre (now sadly no more) when I worked there in the late 80's.

Is one "EMP" and the other "EP"?
I think "Pulse" is man made and "Phenonena" is natural, But a Pulsar is a natural source of EMP.
Maybe it's big horse I'm a Londoner. :{

Only in the later versions how I read it. I was always told EMP was Electro Magnetic Phenomena not pulse -which do you believe is right? Would have thought the faraday cage/screen would have been a bit more substantial than just the casing and with a bigger gap

Great stuff :)

I wonder if theyd be any use after EMP?
They dont look protected or is it in a Faraday cage?

They were landline so probably EMP wouldn't affect them. No cage on them most of the ones I remember in village pubs were sited in the bar and if you turned them on they "ticked" every 10 secs or so. Think there were ones at Black Horse Stansted,  Royal Oak Shoreham  and Duke of wellington Ryarsh from memory. Called WB (warning broadcast). I'll ask my brother in law about the technical bits as he was nvolved in GPO/BT on that side of it
