Bought a couple of nest smoke alarms as they look/are cool, but as my current ones are wired, they'll need hooking up to the current electrics.
Problem is there are 3 wires on the old one and only 2 on the nest. Why is this?
I'm guessing (hoping, is it too obvious?) that blue goes to the blue and brown wires are the same, so is it just a case of not using the wires that connect to the white?
Couple of pics below to show what i'm talking about.

As whoever wired your house is a rough cunt it's not obvious. Brown to red. Blue to blue/black.

 I imagine some moronic apprentice wired it in the 80's.
What do I do with the other wires? Leave them in the block?
Not sure what the yellow/green wire does. That wasn't connected to anything.

Yellow/green is earth. Put it in a connector, same with the redundant yellows

Put the new brown cable to red and the new blue to blue and black, the yellow maybe a control cable if you have more than one alarm? Put that/them in their own terminal block, the green and yellow is earth that should be in a terminal block. Isolate the supply before you mess about, it will either be tapped of a lighting circuit or on its own.

Managed to get it all set up without killing myself, although it came with it's own terminal blocks so used them.
Only problem is the one odd wire has no block (4 different in total, only 3 blocks) so put it in the old block, which now won't fit into the ceiling. I wasn't sure whether yellow/green and yellow would go together so kept them seperate.
Not a big deal, just means I need to go and buy a small block.
Pretty cool, got them both connected to my wi-fi and I can see via an app on my phone what's going on.

What's good about the Nest ones? Am I missing out?

They look good and connect to your wi-fi so I can see whats going on via an app.
Probably loads of other bits too but I just wanted something that looked good.

Erm... ok?
What's going on? *no fire, no fire, no fire, no fire, no fire, no fire, FIRE" .... ? And you're not at home so can't do anything about it other than knowing your house is on fire?

but it looks cool. It's also peace of mind as I work shifts and the missus doesn't.
If no one bothered buying stuff like this, we'd still be using window 95 desktops.
Think i'll get the nest thermostat next. Had my heart set on the heatmiser neostat but the nest would be better if I do away with the current wall dial.

I can understand the thermostat, and being able to control it while out, or from the sofa, but something that beeps when there's smoke, I dunno
Each to their own I guess

You should've seen the state of the one we had up there before, then you'd understand it was yellow. God knows why, we don't smoke.

Also entirely fail to see the point of these. Technology for technology's sake, IMO.
Nest thermostat however

Sounds good to me
No different to spending hundreds on a telly because it has a nice slim frame, whereas a bulkier one will do the same thing for a lot less money.

Smoke alarm would be be beneficial if you were away from home enough for the thermostat to actually be useful.
If you've got both, the thermostat will switch the heating off if the carbon monoxide alarm is tripped.

The yellow will be a link from that smoke to the other. Keep it seperate from yell/green which is earth.

The yellow/green is the one that was left unconnected in the old alarm.
Surely it's supposed to be connected to something?

Yellow + Green stripe is Earth; stick it in a blank terminal block or tape it up as it's not needed in your case (required if you have metal fascias on sockets/switches etc).
Gary was talking about the 'yellow' (only) wires, which go to white on the fire alarm, in the terminal shown in your first photo; this is just a link between the two alarms in the event that one trips, it'll trip the other.

Not quite, as it isn't just aesthetics that change with the increase in price of TV's.
Don't get me wrong, i'm all for smart-appliances but i just think the Nest fire alarm is a bit 'dumb' and should offer a lot more intelligence (using an array of sensors, heat/IR, temperature, oxygen etc to be able to determine if there is an actual fire and potentially call the services on your behalf) other than just sending you a text message when your missus burns the toast

true dom, but I liked the look of it and the fact it's different and a bit gimmicky impressed me.
Cheers for the wiring advice. Need a small connector block for that wire and then it'll be finished.
The fire alarm is actually at the bottom of the stairs in the living room and in the dark, the light comes on which is ideal when coming down the stairs in the dark mornings.
