where to put a smoke alarm?

[trevmai]

Can u put a smoke alarm high on the wall at the top of a staircase or does it have to be on the ceiling?

Any thoughts welcome.

Ceiling mounted is recommended, although you can mount them on walls. It has to be certain distance from the ceiling which off hand I think is about 6". But don't hold me to that.

So they float 6" off the ceiling, do I use sky hooks

Is it 600mm away from the nearest light fitting

Consider air flow, there's no point in having the fire / smoke / heat unit away from central areas where the passage of fire / smoke / heat will be quickly detected.
So keep away from dead zones such as corners away from stairs and doors.

300mm from wall edges and the nearest light fitting IIRC.

Correct the best location is at the highest point at the top of the stairs mounted on the ceiling as already said stay at least 0.5 m away from walls and 300 mm away from a bulkhead light fitting. This is due to the fact that the smoke rises and rolls across the ceilings. When it meets an obstruction it creates a dead area of air space which the smoke does not enter.

A search confirmed that it's 300mm from ceiling edges and light fittings.
I've not seen any references to 500mm.

Gary, thats probably an Imperial 500mm - works out much the same as 300mm, depends on the exchange rate

From your location you may want to contact your local fire brigade. they often fit free smoke detectors for you.
