Discuss CPC used as interconnect on smoke detectors in the Periodic Inspection Reporting & Certification area at ElectriciansForums.net
My initial reaction is a C2. Then when you think about it it is 8-12 volts DC that only has a single layer of insulation.
as a non-electrician, I have a question...
if the cable used to interconnect is at mains voltage, shouldn't it have a cpc, even if the individual detectors don't need one?
If the detectors were non mains supplied, then any 3 core cable would do the job, but T&E presence might cause unnecessary confusion to someone opening up at a later date?
Radio interconnect is an option (a good one, imho) but not an option in rented housing...but in Scotland it will be soon, thankfully.
Hope i have explained that correctly...
The cpc core is uninsulated.essex said:Then when you think about it it is 8-12 volts DC that only has a single layer of insulation.
The cpc in question, does not have any insulation, the sleeving if used will only be an indicator.Interesting one here.

Would I C2 a speaker cable in the wall? No of course not.
If everything is also Class 2 then again I fail to see how to code this.

An obviously correct answer Dave, quite what the problem is I'm not sure, does make you wonder though.Is it definitely 8-12V DC on the interconnect? And is that SELV or otherwise fully isolated from LV with no possibility of a fault making it live at 230V?
I have a feeling that manufacturers say the interconnect should use wiring to the same standard as the supply.
Not on Aico gear. There may be others as well.The interconection cable is 240v isnt it?? :/
