In order to allow sufficient smoke to enter your smoke alarm,
it needs to be placed within 20 to 25 feet of a fire to react
quickly. It also needs to be placed where it can be heard
easily throughout your house.
Single smoke alarms will give a degree of protection if correctly
installed. However, the majority of homes will require two
or more smoke alarms to ensure that they provide an early
enough warning of a fire. For maximum protection smoke alarms
should be installed in all the rooms where a fire is most
likely to break out.
If you only have one smoke alarm it should be located between the point of
a likely fire (e.g. kitchen or living room) and your sleeping
quarters.
Smoke Alarm in a Single Storey
If you live in a bungalow the optimum place to locate a smoke
alarm is in a corridor between living and sleeping quarters.
If your bungalow is large, a single smoke alarm will not be
enough.
Smoke Alarms in Multi-evel Homes
If your house has two or more levels you will need to install
a smoke alarm on each level, this is due to the fact that
a smoke alarm only on the upper level will not activate in
time to let you escape if a fire breaks out on a level below.
