POSITIONING THE SMOKE ALARM
Forthesmokealarmtoprovideanearlywarning,ithastobe
installedinthelocationwheretherestarts.Therefore,Nexa
recommendsthatyouinstallsmokealarmsineachroomandon
alloors.
Single-level home: To achieve minimum protection,
position the alarm in the entrance hall between the living
areas (including the kitchen) and the sleeping areas.
Position it as close as possible to the living areas, and
makesurethealarmcanbeheardbyanyoneinthe
bedrooms. See Figure 1, for example:
Multi-storey home: To achieve minimum protection, position
and alarm in the stairwell (at ground level) and another alarm
abovethelandingonthetopoor,aswellasanalarmonthe
ceiling in the basement at the foot of the stairs. This covers the
basement level, but not crawl spaces and unfurnished attics.
See the example in Figure 2.
Ceiling installation
Hotsmokerisesandspreads,soinstallingyoursmokealarm
in a central location on the ceiling is recommended. Avoid
areas where air does not circulate, e.g. corners. Also keep
itawayfromobjectsthatmaypreventthefreeowofair.
Positionthedeviceatleast30cmfromlightttingsorinterior
ttingsthatmaypreventsmoke/heatreachingthedetector.

Avoidinstallingthedevicealongwayintoacorner.
Position the upper edge of the smoke alarm at least 15 cm and
nomorethan30cmawayfromtheceiling.SeeFigure3A.
Sloping ceilings
In the case of sloping surfaces or ceilings that move up
towards a ridge, the detector must be installed 90 cm from the
highestpoint,measuredhorizontally,becausestillairunderthe
ridgemaypreventsmokereachingthedevice.SeeFigure3B.
NOTE: There must be an alarm in every room (except the
kitchen, bathroom and garage) to provide recommended/
maximum protection. DO NOT POSITION AN ALARM IN
THE KITCHEN or BATHROOM as cooking smells or steam
may activate the alarm. DO NOT POSITION AN ALARM
IN THE GARAGE as there is a risk of it being triggered by
exhaust fumes.
INSTALLATION
Thesmokealarmmustbeinstalledbyaqualied
electrician in accordance with the relevant regulations
for electrical installations. The smoke alarm must have
anuninterruptablepowersupplywhichcannotbe
turnedobymistake.
Allsmokealarmsthatarelinkedbywiremustbepowered
from a single source with a common zero conductor.
Note: Do not connect wire for interconnection to Phase- or
Zero conductor. Disconnect from the power supply that is
to be used.
If no recessed junction box is available, t
suitable junction box adjacent to the smoke alarm's
position. Ensure that there are no other electric wires in
the immediate vicinity of the smoke alarm.
