I would definitely disconnect the ring at every socket split everything and start testing each individual leg, something somewhere is going to show up, if it doesn’t start replacing the the accessories one by one and see what happens
Yes the Aico aint cheap, but if you fit battery Hispec ones in your own property then you can deal with any faults or issues yourself, however its a different story if you supply and fit them for a customer and you keep getting issues.
Hi, baldelectrician doesn't BS 5839 Part 6 Grade D1 Category LD1 compliant regs want mains powered units as opposed to all battery which falls into the BS 5839 Part 6 Grade F1 compliant regs?
Thanks James
I believe that the original question would have negated most of your need to display your knowledge on Fire Alarm systems, however thank you for your manufacturer recommendations
