smoke detector, which one is more suitable for a domestic house

evosteo

as the title reads which type is more suitable for a domestic scenerio

1/ photoelectric
2/ ionisation

or are theyequally as good as each other?

cheers steve

M cebee

at least one of each anyhow

the optical works best with smouldering fires and is less affected by steam and false alarm

ionization works best with fast flaming fires

Bruthal

Yea mixed seems the most positive way, but for domestic, either is easily good enough to perform their life saving function. The optical is said to be less prone to false alarm alright.

M cebee

The optical seems to be the preferred alarm for most locations

unless theres risk of fast flaming fire or dust

but at least one of each

evosteo

so i reckon from what your saying ionisation for the landing

and photoelectric for living room

thats sounds right for them type of fires and the effects that they may have

is it a common thing to fit different types of smoke detectors?

M cebee

I think the ionization may be cheaper

i reckon for LD2 i think it is
on 3 bed semi
prob 1 heat 2 opt and 1 ion

evosteo

im working on my aunts house at the min

upstairs

2 bed
1 bath
1 sq meter landing

downstairs

living rm/ entrance
diner/kitchen

only a small house so i was putting 1 heat detector in the kitchen/diner

smokie in the living room

and 1 smokie in the landing,

whats the rules as regards to the attic??????

is that not the heighest point of the building?
couple of my lecie friends couldnt tell me either, 1 only said if the attic was converted it should have a smokie

M cebee

none in standard attic
but 2 opt + heat downstairs
and smoke on landing i would say

evosteo

is 2 opt + 1 heat a guide line as there is really only 2 rooms down stairs, no hallway

entrance/living room - smokie

kitchen/dining room - heat detector

both room are not even 25m sq

Bruthal

You can use either type, there will be little difference or advantage in either type for a domestic setup. Heat for kitchen, and either type smokes for anywhere else.

M cebee

Prob one of every type so

heat opt ion

I think the opt is preferred over ion in living areas because of false alarms and they work faster with likely fires in these
areas
