Can't find the recent thread about this, but I've been looking at smoke detectors and got this from AICO under System Installation:
"• The supply for the mains powered alarms shall be taken from an electrically protected, regularly used local lighting circuit at the nearest source except for when the house is being rewired, then the supply
will be taken back to the consumers unit and connected to the same MCB as the local lighting circuit,
confirmation of connection method shall be provided from the Contract Administrator.
• All cabling shall be as specified in Clause 411 and shall be installed in accordance with the requirements
of BS 7671:2008 3rd Amendment 2015 (17th Edition IEE Wiring Regulations) and connected in accordance
with the manufacturers recommendations. "
So, there you have it!
