Trying to get an SWA in a riser, well I'm trying to but the chippy who is supposed to be helping me keeps wondering off! headbang
Anyhow, halfway up the riser I noticed a high pitched whine coming from the conduits feeding the flats above.
I was a little concerned so I checked the distribution cupboard and had a listen further up the riser and nothing, just in the middle. :C
It's an ancient setup, all Bill switchgear and imperial cables, VIR yum.
There is also a Porn & Dunwoody lift. :lol:
There is fire alarm and EM lighting cabling running up the riser but it only happens in the middle?
Weird!
Any ideas?
