Whats cheaper these days? 8-core or underlay?

I wouldn't expect and engineer to be able to run Cash/Mentor or whatever systems are in place. Any basics of the industry could be learnt in a weekend so it shouldn't be a big hurdle.
Look at it this way. The engineer/wholesaler/customer/accountant etc all have their own plates filled with their information and whats important to them. The managers job is to keep them all spinning. Sometimes it goes belly up but hey ho.

Don't forget some polka dot stickers.

Do you know what commissioning involves for fire?

Sounds like you could use an RCD or two...
My interpretation is that back boxes should be earthed. But they aren't an extraneous conductive part so you could
the toss. But to be fair, if you were worried about toddlers touching it, why wouldn't you at least kill the power before going anywhere near it. Like you said, you don't know what's behind that socket.

I enjoy listening to radio 4 and watching the documentaries etc so I pay it. If you can afford sky/virgin you can afford the telly license.

I think the best thing i've found on a job was in the attic of an old library. Installing void detection and went through a crawling gap in the eaves to the next roof and found a couple of newspapers from the 50's, couple of old tins of pop and some fag packs and matches. Had a flick through the pristine papers and took them down for the mini museum they had.
Was pretty funny to think that the only thing changes is technology. People will still bunk off for 5 minutes and have a snooze.

Only thing you'd have to watch out for is it being used as an argument tool.
"Well I installed it as it said in this book and i'm right" "Is it an approved book?" "Nope but it's written by someone who knows what they are talking about"
However i'd certainly buy one.

As I stated in my other thread I believe 5839 is wrong on this issue and it hasn't been thought through by the people writing the standard. In James first post i'll just highlight what is wrong and why. I am of the personal belief that fire alarm cables can be ran along side mains with no issues what so ever. I have ran this idea past many tradesmen, technicians and manufacturers and not one has yet to disagree other than "regulations say so" 5839 is a good practice guide for the installation of an electrical circuit. Nothing more, nothing less. It doesn't have different characteristics and doesn't behave any differently from any other type of circuit and should be treated exactly the same in terms of use, protection and segregation. What is stipulated in 5839 is GREY at the best of times and to me, is just plain old best practice. We all know best practice is what we strive towards and work with but it's not always achievable. The situations that i'm referring to when I say that 5839 is when there is no segregation available, the situation is too awkward to provide it or you have the chance to save yourself some money and hours.
The circuits of fire alarm systems need to be segregated from the cables of other circuits to minimize any potential for other circuits to cause malfunction of the fire alarm system arising from:
— breakdown of cable insulation of other circuits and/or fire alarm circuits;
— a fire caused by a fault on another circuit; Irrelevant. The cable is fire rated.
— electromagnetic interference to any fire alarm circuit as a result of the proximity of another circuit; By following 7671 this is a non issue.
— damage resulting from the need for other circuits to be installed in, or removed from, ducts or trunking containing a fire alarm circuit. By By following 7671 and good practice as an electrical installer this is minimized to the extent of is again being a non issue.
In order to facilitate identification of fire alarm circuits, cables should preferably be red in colour, unless another form of colour coding is appropriate. By this means, the possible need for appropriate segregation can be identified, and there will be less likelihood of inadvertent manual interference with the circuits of fire alarm systems (e.g. during work on other electrical circuits).[k) To avoid the risk of mechanical damage to fire alarm cables, they should(Should! because it's best practice, not for any technical reason) not be installed within the same conduit as the cables of other services. Where fire alarm cables share common trunking, a compartment of the trunking, separated from other compartments by a strong, rigid and continuous partition, should be reserved solely for fire alarm cables.
l) To avoid electromagnetic interference with fire alarm signals, any recommendations by the manufacturer of the fire alarm equipment in respect of separation of fire alarm cables from the cables of other services should be followed.By following 7671 when installing cables this doesn't matter because your screened cable has minmised the effects of interference.
I understand that if you work in this way it's not to best practice and requires a variation. Which in itself is silly because you can do anything you want to a fire alarm as long as you pass on the responsibility so hey, who cares? But 5839 is too grey to be considered a concrete technical document. If they don't want people to interpret and implement then they need to remove the factors that allow it in the first place. In my opinion a solid technical idea should be used over best practice. The inspectorate would rather you spend time and money and have everything done to the letter of the law because at the end of the day it's not their time, nor their profit that they are pissing down the drain. They get to come at the end of the job, when all the hard work and swearing has been done and then pick things off.

Because oxo in the space of an hour you went from telling the guy that it would be welcome to then put up or shut up. The guy has been nice enough to take the time and reply. He's clearly passionate about it otherwise why bother signing up here to defend his kit. It's not like he's claiming it to do things it can't.
Then again it raises the big old question of who gives a monkeys what grade it is. If it works it works. They would have more customers if they advertised a bit more and lowered their prices. How many diyers would buy it knowing all they had to do was stick it on the wall? Granted it doesn't look like much but then again I like the look of Pyronix kit and think Risco looks like it was done on a napkin on someone's tea break.
If ADT has taught us anything over the last year or two it's that grading means nothing. Nice looking kit that does the job sells. Customers don't know what grading is and they don't care. I

How does your comms work on this with the Sim card then? Can I just pop in an 02 prepaid card and let it work away?
You`re defending too much.
Post the approvals and let us decide.
After all we have given you all the time and space to reply.
Stop being so bloody rude. Honestly.

Speak to your local window cleaner but it just seems silly someone would install a camera with no easy way to maintain it!

Can anyone reccomend a good gun / staple size? One tool I don't have which would save me no end of hassle. Not a fan of clips either but sometimes they have to be used!

I don't think theres anyone at the top of any business who hasn't done 12 hour days for years. People tend to forget the bosses doing 4 hours a week have usually earned it from years of doing 3 didgit working hour weeks.

Be proud you install the BEST!

My last post on this forum was nearly 5 years ago. I have came out of retirement to tell you this...
I down-voted your last post.
