24v fire alarm cables question

[dylanlennon]

I understand you're not meant to run fire cabes that are used in a 24v system along with 240v cables. The route I'm taking with the fire alarm cable has to go through an old block wall, there are twin & earths running through this entry, is there anyway I could still run it through this entry or not?

Should be a minimum of 50mm separation I believe.

Cheers. I'll be running it in PVC conduit through the entry anyway, will this help? It should be more than 50mm anyway but I'd rather give it some protection.
