Safety service

I am in no doubt that smoke, heat and CO detectors are  Safety Services.

Have a look at the Part 2 definition of a Safety Service.

Then have a look at the list of Safety Services in the Chapter 56 and the Note to Regulation 560.1 where you will find listed "Fire Detection and alarm systems" and separately listed "CO detection and alarm systems".

It would be queer if they were not. For me, I'd want them not only on their own circuit, but also on their own RCBO. However, 2 working days until I get my BBB, so I might be talking piffle. 

Interesting, so Grade D1 and D2 systems can't go on an ordinary lighting circuit, as that isn't classed, protected or routed as a circuit for safety services?
