I need some advice before running the cables for the smoke alarms in my self build.
Can I use standard 1.5mm 3 core and earth to interlink the smoke alarms, or should the cable be fire rated instead? There will be 5 units (3 optic, 1 ion, 1 heat) connected to an independent supply at the consumer box - RCBO or MCB?
Thank you
