Smoke detector circuit.

[UNG]

I'm doing a new build, been told to install smokes detectors on landing which must not be more than 1m away from any bedroom doors. May be just a local requirement.

That doesn't sound very practical on some domestics I've worked on you could have 3 or 4 detectors on one landing to comply with the 1 metre requirement

Blimey, statistics are great aren't they! I'm sure it was something like over half of all house fires being started by cigarettes on the last advertising campaign.

Cant remember where the house was.....But fire was suspected started by an exploding phone charger. On tv news they showed some experiments whereby under test cheap / copied imports do not met UK standards.

Yeah cheap chinky phone charges and laptop chargers etc are pretty good at exploding and overheating, lots of people have done studies but nothing has happened to stop them yet,

Also some of them have clip on plug pins so you can change them to suit the country they are sold in, trouble is the pins part can be put in alive socket on their own and leave live metal available to touch. Or else the transformer part snaps off when you try to unplug it.

There has been cases where these plug in fragrance things have caused fires I make a point of telling people to turn them off when they go to bed or go out

Even today a fire problem........turned out to be an exploding ciggi charger.more common than you think!
