Grade 3

[tinnitus]

Hi guys,

 

Grade 3 question. I’ve only ever done 1 grade 3 system and I’m now questioning if we over done it. It was at least 7 years ago but I remember all cables were in tube and all JB’s were tampered. All DT’s had anti masking too. I was questioned on grade 3 today and was told I was wrong about the containment and JB’s, am I? I don’t see why we would have done this if it wasn’t required, it was a right pain. Anyone have a link to grade 3 requirements? Have they changed over the years? Other option is that I’m just plain wrong.

Mechanical protection doesn't relate to EN50131 that would be covered under BS7671 and all connection boxes must be tampered at any Grade above 1. Masking is obviously a Grade 3 requirement.

All the standards are there but they are copyright protected you purchase them from the BSI website, your company should have a copy.

The best you will get without reading the standards is the manufacturers quick guides that are about, I think the Castle one is in the Downloads section.

All grade 3 must be anti mask?

Op you seem to have an issue due to your last few posts, just assuming based on recent it could be an x y thing. why don't you just ask that question?

Sorry James I’m missing the point. You don’t like how I’m asking my questions here?

Thanks for that reply, great info, much appreciated.

No not at all. I'm sure you can appreciate I always want questions 

I was just assuming there was an overriding issue, sorry

Hey don’t apologise, I’m so grateful for the advice I just dont want to piss anyone off lol. 
maybe I can explain. I done intruder for years, first panel was a logic 4, then an Concept? I think. I stuck to intruder for a long time then moved to fire, CCTV etc. Eventually i landed a door access role. I moved away from intruder and have recently gone back. I’m in a more senior role now but I’m finding things have moved on. I’m trying to pass on knowledge but I’m finding it’s out of date, I need to get up to date and I sometimes come here for a quick reply that pushes me in the right direction. 
actualy, I met my wife because of this forum lol. Someone offered me a job in Cornwall and I moved, that’s where we met! Just remembered that. 
So, sorry if I’m coming across as anything other than inquisitive, I understand it’s frustrating when “engineers” ask silly questions, I completely get it.

I think JW thought all your latest posts where connected to the same question (XY problem). It's can lead you down the wrong path asking questions around the problem like this. No worries if that's not the case .

 

I often find with a lot of these situations the lines between what the regulations say and what engineers have picked up gets blurred.

Opinions on what is right, wrong and rough overshadow what the written text of the regulations you are fitting to say.

Now don't get me wrong there are some things in the regs that you may interpret differently to someone else but they are the where it comes from so best from the horses mouth sometimes.
