Super_Paulie Posted May 8 Share Posted May 8 afternoon. Is there any particular reason why i couldnt use a central junction location to distribute my phase, neutral and interlink to my smoke alarms? My reasoning being that i would rather not have to remove final flooring in the future to get to the back of the alarms to chain it to a new one, i could have a Wago enclosure or similar in an easy to access location say under a hatch in the landing. So i can get all my new alarms in now in the new side of the house and in the future i could add in new to the existing part without having to pull all the new floors up. BC are happy with my proposed locations to LD3 but i would in the future add more to upgrade to LD2. Link to comment Share on other sites More sharing options...
ProDave Posted May 8 Share Posted May 8 No reason why not, but I would not. I would just run cables to the ones you can with a spur running off ready for the next stage, long enough to reach it's eventual destination and terminated so it is safe until you are ready for the next phase of the job.

mike2016 Posted May 8 Share Posted May 8 I'm looking at using Aico smoke alarms with a 4 core wire to power & Connect them and a home assistant extension to get alerts into some type of trigger that can power down MVHR and pulse me an alert on my mobile. Interesting when sequencing makes you think ahead and future proofing to avoid issues - these forums always make me look around the next corner with the replies.

Wouldn't the following occur with a decent fire (likely to initiate from an electrical issue unless you smoke). Main MCB - Power trips - so the battery in fire alarm is now powering it. Home assistant off, as there is no power MVHR off, as there is no power So why bother with the automation - not sure going to do anything. Link to comment Share on other sites More sharing options...
mike2016 Posted May 8 Share Posted May 8 It's about getting an early alert if I'm out and about. All the alarms will sound locally if any detect smoke/heat (depending on detector) on mains or battery as you've stated. But isn't there a likely gap between a room fire vs a structure fire with only the latter likely to start interfering with whole house electrics rather than a single MCB/RCBO in the case of a room? It would be nice to be able to plug in extra detectors to extend as the original poster wanted but we'd have to have sockets in the ceilings for that!

Super_Paulie Posted May 8 Author Share Posted May 8 I guess i could just add and leave cables and then connect to them with Wago when the time comes, it's just adding joints whereas I thought the central location might have been the better option for future expansion and less joints in the system.

FuerteStu Posted May 8 Share Posted May 8 I've not refurbished the kitchen yet.. But I've already fitted the three smokes in the utility (boiler and washing machine) and the upstairs hallway.. I left a loop in the middle of where the kitchen will be, right above where I've cut a hole that is temporarily plugged. When I fit out the kitchen, I'll pull the loop down and cut and terminate the head then. It means it's in one radial and they're all linked.

In Scotland you are now not allowed to install smoke detectors in a kitchen you have install heat detectors - less false activations Link to comment Share on other sites More sharing options...

House and all automation runs off central batteries, so only the tripped circuit is lost. It's definitely worth knowing if the smokes have gone off. Someone on here connected their Aico alarm relay to a shelly which is great. With a shelly pro (ethernet connection) it's even more reliable. Of course if the fire isn't extinguished and you aren't there- knowing about it is a bit of a moot point. Link to comment Share on other sites More sharing options...

A bit like watching your house getting burgled on the 15 CCTV cameras you've installed. 1 Link to comment Share on other sites More sharing options...
