Good Morning,
We have just taken over a system from another company it is a single loop morley zx with Apollo devices. It is a high rise block and has a loop going up the cable riser with a zone isolator on each floor the loop is connected together on each isolator with a radial on the out side of the isolator switching the negative. I have never come across a loop like this before can see many reasons why it does not comply with the current BS. But before I let the client know what I have found can I ask if anyone has come across this before.
