IN COURT?

And yet again Mr Yale pops up to suggest systems being installed are wrong, nay, Illegal.
Then shows us that he really has no idea what he's talking about. Clearly not even read the basic guides on Gradings, let alone the relevant standards. Yes Mr Yale, those documents we have to buy and you just ignore.
tat product and tat advice.
But eh, he's cheap! Unfortunately he's a classic example of the old adage. Pay cheap, pay twice.

Simply using two sensors or more for the same location seems unethical to me.
For example two pir sensors in one room both pick up the bright headlights of a car turning outside

As has been said to you MANY times, you just don't know, do you?

Two detectors in the same room are perfectly OK, they just have to be of different technologies.

Just so you know what that means, for example, Pir in one corner, and a DualTec in the opposite.

[ DualTec - PIR & Microwave in the one unit, what will trip one technology will not trip the other ]

Thankyou for explaining that.
The post submitted didn't make that clear.

I said unethical!
The proper reccomendations have been explained to me by Europlex.
The post didn't make it clear that TWO different technologies had been used. It appeared that simply extra sensors of the same TYPE had been used which as you should know as explained by Europlex WOULD be wrong.
Unfortunately none of my clients have had to buy twice so you are wrong yet again. Twice in the same reply... good going.

Surely designing a system like that is illegal?
.

No Mr tat, you didn't say unethical. Care to read your post again.

You know nowt!!

ok so I thought doubling up sensors would be ilegal as in not complying with the rules I certainly also said unethical..
shoot me!
I'm sure the Police wouldn't be happy turning up to a false alarm. If they looked they might just notice a contravention of regulations but it's doubtful they wouldn't notice and the ARC wouldnt tell them.

odd. In the corner of my shop there is a triple tech in the corner (one with 3 coloured lights in one), then further along the same wall, about 6 foot away, is another one, the same, pointing the same way. Then in the middle of the area they point at is a 360 triple tech. All overlook the cigarette kiosk and beer area.

And the system has how many zones?

Unless 'youtekkinthepish' (joke) they are DualTecs of some sort, one led for one technology, another led for the other technology & the last led to indicate an alarm condition, the first two indicate that technology has detected something.
