Alarm 2000 Iss 5
26
If the residence is very large and/or the corridor or hallway is more than say 15 metres
long, one Smoke Alarm will not be sufficient. No matter where it is located it will be more
than 7.5 metres from potential fires and there is the likelihood that the warning will not be
heard throughout the areas requiring protection.
In residences with more than one sleeping area, Smoke Alarms should be placed between
each sleeping area and the living area.
4.2.4 Multi Story Dwelling
If the dwelling is on more than one level, you will require at least one smoke alarm on each
level. The first should be located in the lower floor hallway near the stairs see Figure 8.
Smoke is likely to be detectable in this hallway before it reaches the upstairs landing and
bedrooms.
The second Smoke Alarm should be located upstairs adjacent to the bedrooms. The
downstairs Smoke Alarm is unlikely to detect the smoke from a fire in the bedroom area
upstairs. Both Smoke Alarms should be interconnected to ensure the earliest possible
warning.
4.2.5 Maximum Protection
For maximum protection locate an Alarm in all the rooms where fire is most likely to
breakout, selecting smoke or heat as appropriate. The living room is the most likely place
for a fire to start at night, followed by the kitchen and then the dining room. You should
also consider putting Smoke Alarms in any bedrooms where fires might occur, for instance,
where there is an electrical appliance such as an electric blanket or where the occupant is
a smoker. You could also consider putting Smoke Alarms in any rooms where the
occupant is unable to respond very well to a fire starting in the rooms, such as an elderly
or sick person or a very young child.
