Smoke Alarm's

[electricshock]

Dedicated circuit and stick it in with one of the lighting circuits. You can make it separate later on if need be.

Ive always wired the smokes back to the DB and double it up with a lighting circuit, if the customer ever requires them to be on a seperate circuit, its easily achieved.

However if you had them pulled off a random lighting point, you have no other options for them to ever be seperate should it be required, i totally agree with the above about being on the lighting circuit as you would be aware you had no lighting and would rectify the issue, basically forcing smoke alarms on people, because as sad as it is, people take the batterys out to stop them bleeping they are the ones who usually burn to death for the sake of a £1 battery

Always as a dedicated circuit, on an rcbo or mcb that is not on an RCD

So what happens if its accidentally knocked off at the board? or the breaker fails?

you wouldn't be aware until your burning to death and wondering why the smoke alarm failed to go off, regardless of what the regs say i see it as bad practice

Why not on an rcd 17th edition board???
Is there a reg that says that heats and smokes should not be on an rcd?
Im not saying your wrong but that just means that ive 1st and 2nd fixed 38 flats for barratt homes wrong and the architect is wrong which i very much doubt!

Ever heard of a battery back up? :lipsrsealed2:

No i have not, is this a new thing?

So.. breaker gets knocked off and battery runs flat, so it starts bleeping, what do you think the average idiotic customer does? yes thats right... takes the battery out

So how does the smoke alarm operate in the event of a fire with no mains supply and no battery back up?

Never missed you to be honest but as your here now I will say =Hello nice to see you. Mike

If someone is stupid enough to disable their smoke alarm thats their own problem. I wouldnt lose any sleep over their own stupidity.

I would dismiss you if you did that, No need to have 2 phase conductors in a breaker these days on a new install, continuing the lighting circuit and adding the smokes is quite normal by some and I won't argue that, but purposely doubling up pretty poor IMO. For what it is worth and it may not be much I always add fire detection on it's own circuit, that said I have no issue with fire detection on lighting circuits.

Sacked for two conductors in a breaker? what harm does it really do?! I take it you are not referring to rings aswel!

Can't mess with aicos. I have to smother the things to keep them quite.
