The link below may help the last bit may help as you need more information. Why is such an alarm system being specified. If I had got to quote for such a job I would get a rep from firm alarm company to price it up have used channel safty systems in past.

Only by quoting Grade and Category can a meaningful and effective alarm system be specified, e.g. Grade D, Category LD2.

I could be reading this totally wrong but when the client specified a 'grade A' system you are sure he's not using a turn of phrase and just means he wants the best system?

Probably a reason for needing more than standard mains operated system could be amount of floors or something. Had this recently on a job were building inspector wanted an all singing and dancing system due to fact loads of fire walls were being knocked down and doors taken out but in the end a standard sytem was put in because they changed the plans so not so much structual work was done.
