Smoke and carbon monixide detector connected to your electrics

I am house rewired and the electrician suggested the above. I just want to know whether they are any good as I do not want it started to bleep when cooking. Also does anybody know whether they cn silence them if there is a false alarm? Thanks

Good afternoon: We have a heat alarm in the kitchen interconnected to smoke alarms....all mains powered..see more here

Are they sensitive and can you turn off manually? Any idea how much one cost? Electrician is thinking one copmbined with carbon monoxide. Thanks

Cost - £40 (incl. shipping) from these guys.

I'm not sure I'd bother, you can get a battery operated combined detector for £29, which doesn't involve an electrician and is inherently safer because you don't have mains cables. With 10 year batteries battery life isn't a problem and the recommendation is to replace the sensor every decade or so anyway.

Good evening: the cheapest option isn't always the safest option: hard wired systems are superior and mandatory under Part B for new builds and would be advisable for a rewire.

Do you have any evidence for that assertion? There doesn't appear to be any in the link.

Hi

Hmmm


Which alarm would be the most use in the event of a fire?

The one connected to the mains electric with a sealed in battery back up.
Or the battery powered one . (with no battery 'cos I borrowed it for the door bell)


Would you consider the mains one superior?

I have made up my mind, not going to have the mains ones. They can be a nuisance. I prefer the battery operated one, electrician does not understand why and he said he will put in the certificate no smoke detector has been installed. I am quite happoy with that as long as he certificates all the other works he has done. Thanks

I have these but in the kitchen I have a heat sensor rather than a smoke sensor one. Hence it should only go off when there is an actual fire, rather than me burning the toast!

I think you've missed the point a bit here as mains or battery ones will both go off if there is smoke - so the 'nuisance' potential is exactly the same!

Mains are by far preferrrable as you don't have to worry about changing the battery for years.

Heat detectors are used in the kitchen as they detect heat not smoke, so minimising the risk of being set off by your burnt toast.

I think your electrician is giving you sound advice...

We have mains ones and wouldn't ever go back to just battery ones. They are all interlinked so if one goes off then all of the others do to - however, you can silence them by resetting one (you don't have to go around each one) I would highly recommend you go for mains (with back up lithium battery)
