Try that with LSOH cable which is non fire propagating and will not give off the fumes standard twin & earth willReading that 422.2.1, towards the end it does say for BD2/3/4 the cables shall be fire rated...
I did set fire to a cable to see what happened - not as bad as I'dhopedthought with the cable self extinguishing within about 10sec. Not surprising it failed IR testing after meeting Mr Rothenberger. Now for the pics

So what did the EICR say.Ok great, thanks for all your advice guys. And for those who were asking it was a grade D system
FP200 not used for smoke detectors- C2So what did the EICR say.
Potentially dangerous???FP200 not used for smoke detectors- C2
Had no regulation reference or anything
Potentially dangerous???
I would say it's more to do with a fire alarm service report issue and not a eicr.No - C3 maybe?
I would contact them and ask their reasons. A Grade D system does not need fire resisting cable unless the requirements of BS7671 could only be met by doing so. I find it unlikely, though not impossible the reason is for an inappropriate wiring system on an escape route. More likely they have misread BS5839-6 or confused it with BS5839-1, the fact they have given a Code 2 is neither here nor there and it would be interesting to know why they have picked up on it to resolve your problem.FP200 not used for smoke detectors- C2
