Do you install fire alarm systems?

Chris Pearson
Bit of thread drift going on elsewhere, so I have started a new one.


"Do you install fire alarm systems?" - a question which is asked on insurance renewal, but what does it mean?


IMHO, there is a world of difference between providing a mains supply with third core for linking for a couple of smoke detectors and a heat detector in the kitchen on the one hand (i.e. the minimum grade D2 LD3); and a full on panel with separate detectors and sounder etc. (grade A LD2) in a large house. I consider myself perfectly capable of providing the former, but have never attempted the latter.


So where does the threshold lie? I'd be interested in views on certification too please.

    The real problem is exactly where fixed wiring and appliance cross over. I think a normal fire panel system (24V normally) is an appliance. The wiring is part of that appliance and does not come under BS7671.


    Make your mind up Dave!

    The output side of the alarm panel is still classed as fixed wiring and also as a safety circuit, it still needs to be installed as all other lv wiring systems in BS7671, needs to be supported correctly etc throughout it’s entirety. We may only record the 230v side on the EIC, however the system itself has another test certificate to record results such as IR and Impedance etc.
