What Is The Best Home Intruder System Available On The Market Today

[Guest Umster]

You can spec a system as a grade 2x. You can then add signalling as an 'extra' without affecting the grade.

I can't see a benefit really, just spec it as a 2a/b/c in the first place?

Hi Brian,

Please can you advise me what a, b ,c mean? in as much detail as you can, Be as techincal as you like.

Thank you kindly.

2b = monitored with single path signalling

2x = same level risk as Grade 2 but with no signalling

2b = monitored with single path signalling meaning? central station monitoring eg. custodian not BT Red care

Thanks

It's quite indepth really.

The grade number is relevant to the risk and equipment used. The letter that follows is relevant to the transmission equipment.

2A should have a signal transmission time of 60seconds, 25hour reporting and the path should have 99.3% availability. There is no restriction on the security of substitution of equipment or obtaining the information transmitted.

Wheres a 2D system should have a signal transmission time of 20seconds, 180 second reporting and the path should have 99.8% availability. There should be measures to detect equipment substitution and encryption to prevent the obtaining of information.

There's more to it than that but that's an idea as to the difference in grades.

One benefit to speccing a grade 2x and then adding signalling is that because you added signalling as an extra, it doesn't have to have the 25hour reporting as it would if you specced a 2A.

My 24,

I am not in the trade at all, so I don't really know, but I did find this PDF by the SSAIB online which mentions that it is currently acceptable to use ungraded MRS because graded/tampered ones are not necessarily available or effective.

Thank you for this info. Fully understood.

Something interesting....

I've just been going through all my quotes from all different companies, both SSAIB and NACOSS

It's seem that only SSAIB do Risk Assessments. is this correct?

Thanks

All installers installing to EN50131 have to carry out a risk assesment regardless of who they are approved by.

Hello again,

I have a choice between two manufactures of PIR DT detectors.

PYronix DT or Gardtec DT, which ones to go for?

Thanks. B)

Pyronix

Pyronix

Out of the two Gardtec, and thats coming from a company that does not use Gardtec products.

Hi, so why do you say GardTec??? what's better?

what do you say Mr Alarmgard?

I have never fitted any of the Pyronix DT's but I have fitted the Gardtec ones.

So I would in this choice use the Gardtec DT's.

But in everyday use we use Honeywell DT's or Gaurdall.
