hi all, hope your all well?

just after your ideas about 12V smoke alarms?

if you was doing a new build would you use these 12V smoke alarms with a good alarm panel with sounders around the building asigned to work as fire or with you stick with the mains interlinked? where do you stand with the building regs with using the 12V alarms?

any ideas?

Proper 24v fire system would be best, if it's a fair sized premises.

Sounders can be fitted with/in the smoke heads.

If a Grade C system has been specified under BS 5839:Part 6 then smokes as part of an intruder system will meet it, provided that the standby battery has been upgraded to give a minimum of 72 hours.

Well first question is Domestic or commercial? two different kettles of fish.

Usually planning/building warrant. Depends on what it's like in your neck of the woods. Personally i'd stick a 240v mains smoke detector in the downstairs hallway and one on the upstairs landing. make them interlinked. Cheaper, easier to fault find (hardly ever go wrong complies with 5839-6 Grade D) Honestly unless your insurers tell you what you need, you live in a mansion or its sheltered/communal or tenanted housing then don't bother doing anything fancy. It will lead to headaches, bills and more paperwork than what's needed.

Most people don't want an ugly detector spoiling thier nice ceilings. To me it just seems more hassle than it's worth.

If the room needs a smoke detector, how is (mains/battery/12v/24v) going to make a difference.

Been asked to fit (Category L4) Twinflex or Analogue addressable fire systems in our large domestic new builds lately.

If small/medium sized domestic, fit mains interlinked.

Easier than making the intruder system 72 hours standby.
