How old were the detectors?
>10 years then they need to be replaced, replacements being mains rf units..
I don’t see how the using the cpc can be a C1 or C2?
The interconnection is only 9 volts.
I would code it as a C3

I am sure some detectors just switch 230v to the link wire when they are set off.

 

[tony clark]

i think they where approx 7years old,

Yes but doesnt the cable itself have to have a cpc

No But the circuit should if ADS is the protective measure

It is an interesting thing - if I have it correctly - each point in the circuit is to have an earth available (Richy’s 411.3.1.1 ) and if it’s ADS have a cpc run in “immediate proximity” to the lives ( Reg 543.6.1 ).
So to my understanding, Reg 132.16 tells me if they don’t want it fixed I should join @tony clark back in the van. Any tea Tony?

....and if neutrals are taken as ‘live’ then all those houses where a separate neutral without CPC has been run around the lights.....

How big is this van?

Cpc means circuit protective conductor, meaning the entire circuit, not just the outlet point.
Using the cpc for anything else is wrong.

You would have to label the same as old lighting circuits without cpc; class II only, no metal etc

For goodness sakes, use the T & E as a feed and tell the client that they need radio links, if they are not available for that model as they are 7 years old then replace them. At the end of the day you did not install them and use the CPC as the interconnecting link, even if it is extra low voltage on many of them, all you can do is give the client your knowledge to keep them safe, its up to them if they choose to use A N other to reuse the existing wiring
