Guest sens7 Posted January 19, 2005 Posted January 19, 2005 Wondering if anyone can shed some light on the EN regs? Will a "bells only" system confirm to any of the EN system grades? If not what will the basic grade one system have to include i.e monitoring etc.?

breff Posted January 19, 2005 Posted January 19, 2005 Bells only=Grade 1, all systems require tamper circuits! The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not)

breff Posted January 20, 2005 Posted January 20, 2005 That 60 hours can be halved if mains fail is signalled to the ARC The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not)

A bells only will be grade one from wot i can gather. Aritech now badge all there stuff up with wot grade it is, and have been doing so for sometime now.
