Guest Peter James Posted October 14, 2006 Share Posted October 14, 2006 Grade 2 and 3 is not something that is easily explained in a few words. Basicaly it is levels of security for example grade three must be metal cpu, the detectors are anti mask (an extra technology that prevents the detector being obscured). There are several programing differences, and the signaling for grade three is dual path. Grade 2 has varios levels and there is nothing to stop a grade 2 system having grade 3 components or signaling. The level of the system is graded by the lowest grade of component installed, so if you have a system made up of all grade 3 kit apart from a single grade 2 detector, the system is grade 2. Quality is not really an issue, I would expect both grade 2 and three systems to be manafactured and installed to a high standard of quality, a grade 3 system will not nessasarily be any more secure than a grade 2, we install many grade 2 systems that would be classed as grade 3 if they had the grade 3 anti mask detectors, but anti mask was not used because deliberate or accidental anti masking was not an issue. There is more to grading and there is different levels to each grade 2x -2b but I hope this is helpful Peter Link to comment Share on other sites More sharing options...
Guest Valhalla Posted October 20, 2006 Share Posted October 20, 2006 Hi there, I concentrate more on the Grade 4 end of the market, but I have found the "PD6662:2004 pocket guide" very useful, its available as a pdf file download at this website:- http://www.coopersecurity.co.uk/default.aspx?page=en50131 Link to comment Share on other sites More sharing options...

IPAlarms Posted October 21, 2006 Share Posted October 21, 2006 Hi there, I concentrate more on the Grade 4 end of the market, but I have found the "PD6662:2004 pocket guide" very useful, its available as a pdf file download at this website:-http://www.coopersecurity.co.uk/default.aspx?page=en50131 Thanks for the link - I have just started trying to learn about the new standards and found the booklet very helpful. One thing that threw me is that installers are now asked to predict how experienced the burglar will be when he comes to break into a particular property Easy if the site is in Salford banghead but not so easy if you are out in the country. Is there a list of burglar gradings that we can refer to ? (only joking) Free Alarm Monitoring over the Internet from IP Alarms Link to comment Share on other sites More sharing options...
arfur mo Posted October 22, 2006 Share Posted October 22, 2006 That isn't totally correct.The different catagories are determined by the expertise of an expected intruder and the type of tools and equipment available to him. so the category 3 is someone very conversant with alarm systems and who has a good range of tools and test equipment. category 1 is a smackhead with a screwdriver. hi paul, i'm troubled by this analagy to, as surely a smack head will try his luck on a high security site and could be succesful (like Fagin & Buck House), and is anyone going to say a well equiped well versed pro intruder will just too snooty and turn his/her nose up at an oppertunistic target? regs alan If you think education is difficult, try being stupid!!!!

Guest Posted October 22, 2006 Share Posted October 22, 2006 Grade 2 and 3 is not something that is easily explained in a few words. Sticker on the equipment..... When deciding what grade a premises is we have to decide what type of intruder will be . Spec grade 3 controls & detection ect... & leave the ATS to determine the overall grade piece of pish Link to comment Share on other sites More sharing options...
arfur mo Posted October 22, 2006 Share Posted October 22, 2006 .. yeh, I know. Is isn't possible to know with any certainty what kind of crim. may arrive.... but I don't make the rules. Hi Paul, i'm sure if you had any input they would be far more lucide and practacle . mind you, thinking about it, my 14 month old grand daughter could achieve a decent level to. seems like the 'legislaters' expect us to think like crim's, so now we have to take 'criminal sociology degree's' perhaps. it seems we have to be antiques and art specialist too, as example some things like prints i have looked at, and though of as just bits of 'tat' were incredibly expensive art. Chubbs used to have a 'rider' on their spec's saying 'the client is responsible to notify any item or fixture of any high value to the companies surveyor' or something like that (it was over 30 years ago) perhaps now more prudent to use something like that and add "likely to be of interest to a super intruder withan @A@ team arsenal to play with". so i see the barmy army are on their usual walk abouts again regs alan If you think education is difficult, try being stupid!!!!

IPAlarms Posted October 22, 2006 Share Posted October 22, 2006 When deciding what grade a premises is we have to decide what type of intruder will be attracted by the premises and the contents and what experience this expected crim. will have and what tools and equipment will be at his disposal. If we decide on category 1 and it turns out that a category 3 intruder pays a quick visit - what then ?

Guest Posted October 22, 2006 Share Posted October 22, 2006 If we decide on category 1 and it turns out that a category 3 intruder pays a quick visit - what then ? well the alarm will still work....... in my case its all grade 3 apart from the cleint wanting cheap ATS (if its non domestic)........... following raid install dualcom like I said peice of pish Link to comment Share on other sites More sharing options...
