Defibrillator installation

IronFreely

Hi, Ive been asked to fit a couple of defibrillators at my local town hall. I dont know why but there’s something in the back of my mind telling me that there may be some specific requirements. I might have a memory of being told once that theres a specific city and guilds AED installation  course but google hasn't given me much there… I had a look through my shiny new brown book but didn't find anything of significance, I like the cover of new book, feels tougher than the previous ones but i did rely like that calming shade of blue.

Im your average qualified sparks who mostly rocks the domestic world and I’m obviously signed up to a scheme and have the usual insurances and qualifications. Any way so, beyond the normal every day rules regarding fault protection, earthing and bonding etc is there anything else anyone would advise me to consider before accepting the job?

One thing I’ve considered is that these things go on an exterior wall and appear to be in metal cabinets, having not yet received the instructions I may find the casing is technically an exposed conductive part and may require earthing so that may bring up the question of exporting PME.  However I have been told by the person booking the work they are rated IP65 and he believes they are class 2/double insulated so that would suggest perhaps the external casing would not require earthing and as you cant plug a lawnmower into it perhaps its not going to be a worry connecting the it to a final circuit on a property with PME. 

Id appreciate some thoughts and advice especially from anyone with experience of fitting them as Ive never been asked before, id rather come on hear and ask a rookie question than make a rookie mistake when by now I should know better! 

Thanks in advance

    The manufacturer's instructions would be my first port of call - there may well be differences in requirements between different makes/models.  In general though, I gather they need power a) to keep the internal battery charged, and b) for the outdoor ones power for a small heater to guard against condensation and the like; so double insulation or even SELV/PELV seems quite feasible.

    I'd doubt that the external cabinet would count as an exposed-conductive-part - to have a realistic chance of being made live by a fault it would have to contain mains wiring with only basic insulation over it - and as the inside of the cabinet would have to be accessible to get the AED out, I doubt that would be the case. As long as there's a bit of care with cables passing through holes (keep the cable sheath intact, no sharp edges etc) and of course no part of the enclosure is directly used to house exposed wiring as if it were a Class 1 enclosure, I don't think there's a worry there.

    As always Andy you’re making a lot of sense. My main concern was that there is a specific requirement for these AEDs which is niggling at the back of my mind, it might just be because my head is remembering specialist medical locations containing defibs used directly on the heart through an open chest, which if I remember correctly deems the location a class 1 medical location set apart from a boring class 2 medical locations where our hearts are not operated on and you just get a plaster for your booboo. Something like that at least. Been years since I delved into that when I was but a boy in a classroom.
