Alarm

And with negligible insertion loss...

Wrong again! Less profit actually. Less labour cost = less direct profit.

See, you just don't understand.

Naw, just make it reactive loads.

You're a bigger fool than I thought.

You know, you're damn right. I am a bloody fool. I sold my business a couple of years ago and put just under £2m in my bank (after tax) and here I am on this newsgroup putting up with wankers like you.

Yes, I'm a fool alright.

I know you you feel.

And makes useful clicky noise to reassure one it's working ...

Owain

It's always nice when people boast about how rich they are. Hope it made you feel good, as well as looking a prat to everyone else. Apart from IMM, of course.

You've certainly demonstrated that over your lack of understanding of relays and their functions.

I never point PIRs at windows/sources of sunlight. Last time I looked at the instructions that came with a PIR it tells you exactly that as it may create false alarms. I know many installers still do position them towards the windows but as long as the sensor manufacturer's say not to, then I won't.

In London estimates from installers will be about £600 to £1200. The higher normally being from the famous names (ADT etc). They will also include monitoring as part of the price which you will have to pay for seperately so even those original prices are subsidised to a degree because of the money they make from monitoring contracts.

To buy the stuff yourself you're looking at around £150.

Don't worry about it Dave, a fool and his money are soon parted. But then 2 milli pounds isn't a great deal anyway.

Boast? No, not a boast at all. It's nothing to boast about. £2m is small these days. I actually sold my business cheap because for many reasons the time was right for me to get out. So wrong again, I don't boast.

Maybe that's why I have a degree in electronics - lack of understanding.

That's what I said earlier.

So much for the degree in electronics then. Though I guess you won't understand that either.

LOL!

You're right, but because most of the loads driven by relays on what I work with are inductive (pumps, gas valves and fans), e.g. inductive seemed a fair comment to make

Well yes, what you say is correct but does not prevent break in as very few would be deterred by a "Smokecloak installed" notice That's assuming that they can read.

Always liked the South African car hi-jack deterrent. Concealed flame-thrower fitted underneath the car and activated by the driver if threatened. Legal in SA as well.Wonder if British gas are thinking of adapting it for the house market.

mats. Maybe the odd ultrasonic too.

Concealed door contacts are very useful as final exit/initial entry. Still used for proper pro work.
