Pocster Posted July 13, 2021 Share Posted July 13, 2021 I need to order these up. So have 2 core + earth to each location. 6 fire, 1 heat required Looked at https://www.safelincs.co.uk/radio-interlinked-smoke-alarms/ But they are like £70+ each!! ( with wireless comms between them ) Any other recommendations??? Also need a carbon monoxide detector ( for log fire ) assume this does not need to trigger the others for an alarm ....

Pocster Posted July 13, 2021 Author Share Posted July 13, 2021 Cheapest one https://www.safelincs.co.uk/fireangel-pro-connected-mains-radio-interlinked-smoke-and-heat-alarms/ Can't seem to find any mains/wireless comms ones cheaper. Just a case of suck it up then ? Link to comment Share on other sites More sharing options...

Pocster Posted July 31, 2021 Author Share Posted July 31, 2021 Thinking about this . Can I just have battery powered wireless interlinked alarms ? Much cheaper . Doesn’t require a sparky to install them . I can just ignore my power cable to each alarm point then . Regs in a domestic new build aren’t it *has* to be mains powered are they ??

ProDave Posted July 31, 2021 Share Posted July 31, 2021 The time to ask was before you plasterboarded. 2 core & earth to first alarm, then 3 core and earth from that to the next, and the next and the next etc. No need for radio linking. The radio linking bit costs more than the basic alarms. Another vote for Aico. If they are too expensive look on ebay but CHECK the "replace by" date if buying from ebay, lots of old stock about. 1 Link to comment Share on other sites More sharing options...
Onoff Posted July 31, 2021 Share Posted July 31, 2021 Aico or at a push Aico. Saying that I have once fitted Kidde when I couldn't get Aico in a rush. Wired which were OK tbh if a bit bulky. You can with most get a little test station from where you can test your alarms or in the event of a trigger hush all those except the ones going off. Aico do really good installer/specifier pocket book guides for the sake of a 5 minute sign up. Link to comment Share on other sites More sharing options...
Pocster Posted August 1, 2021 Author Share Posted August 1, 2021 So do they HAVE to be mains ? Can I have battery but wirelessly connected ? Link to comment Share on other sites More sharing options...
Pocster Posted August 1, 2021 Author Share Posted August 1, 2021 This seems to say yes https://www.aico.co.uk/standard_regulation/fire-building-regulations/ The wireless aspect isn’t the real cost . As you can get battery fed wireless ones for 30 quid a pop Link to comment Share on other sites More sharing options...
ProDave Posted August 1, 2021 Share Posted August 1, 2021 3 core cable is cheaper than wireless modules. Link to comment Share on other sites More sharing options...
dpmiller Posted August 1, 2021 Share Posted August 1, 2021 plus you can go hybrid- cable the easy ones, then wireless off them too. I chose to go wireless and to add the fancy test button and a relay box to integrate MVHR control and CO sensing. 1 Link to comment Share on other sites More sharing options...

tanneja Posted August 24, 2021 Share Posted August 24, 2021 Is there any way at all of getting black smoke and heat alarms for a residential house without needing to go industrial with panels etc? I saw so many when I did an initial look but after calling a few online stores none know of any domestic sensors that will meet UK regs (i.e. mains powered with battery backup) Link to comment Share on other sites More sharing options...
