addled?? never heard that one before!

Only reason I didn't post part 2 is that I have no idea what you're on about now!!

:wacko:

If you don't know......ask.

I'll explain.

CSA is expressed in 2 different measurement units, square mil and circular mil.

comparing the 2 without converting them would be like comparing inches to cm.

I was just explaining the differences between them and how to convert one to the other and visa versa.

now we come to issue using screened twisted pair cable... :yes:

try to install CAT5 screened PATCH CABLE instead of UK type ALARM CABLE. It is similar to UK type alarm cable ( multistranded ) except it is twisted pair. Remember to connect screening to panel casing.

If it doesn't yet work out, disable the internal transformer and use external one ( SAFETY ISOLATED (I can sell you one if not available in UK (this SHOULD be ok with your regulations ))) in tamper proof casing which is earthed. Use only under 1m UNSCREENED cable from transformer to panel. Do not earth panel casing ( IF it is ok with UK regulations (should be because it is _extralow_ voltage )) but connect all screening to panel casing (or if casing is plastic to the earthing pin of the panel).

I bet it works. If it doesn't, I'll fly to UK and offer you a cup of coffee (or tea (or beer))
