Breezer, I'm just checking what I thought I'd learned properly is correct.
Can you please clarify whether mains powered smoke detectors (as opposed to intruder or proper fire alarms, where I know to fit an independant supply) may be wired from a lighting circuit. My understanding is it is preferred to run a seperate circuit, but that connecting - in a domestic premises where a fire alarm is not required (House in Multiple Occupation, certain multi story builings etc.) - smoke detectors to a lighting circuit is an alternative provided the circuit is labled as powering smoke detectors.
