POSITIONING THE SMOKE ALARM
For the smoke alarm to provide an early warning, it has to
beinstalledinthelocationwheretherestarts.Therefore,
Nexa recommends that you install smoke alarms in each
roomandonalloors.
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
make sure the alarm can be heard by anyone in the
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abovethelandingonthetopoor,aswell
as an alarm on the 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.
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.
Ceiling installation
Hot smoke rises and spreads, so installing your smoke alarm
in a central location on the ceiling is recommended. Avoid
areas where air does not circulate, e.g. corners. Also keep
itawayfromobjectsthatmaypreventthefreeowofair.
Positionthedeviceatleast30cmfromlightttingsorinterior
ttingsthatmaypreventsmoke/heatreachingthedetector.
Position it at least 1 metre away from the wall. See Figure 3A.
Wall mounting, if ceiling mounting is not possible
Avoid installing the device a long way into a corner.
Position the upper edge of the smoke alarm at least 15
cm and no more than 30 cm away from the ceiling. See
Figure 3A.
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 highest point, measured horizontally, because still air
under the ridge may prevent smoke reaching the device.
See Figure 3B.

roomandonalloors.
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
make sure the alarm can be heard by anyone in the
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abovethelandingonthetopoor,aswell
as an alarm on the 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.
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.
Ceiling installation
Hot smoke rises and spreads, so installing your smoke alarm
in a central location on the ceiling is recommended. Avoid
areas where air does not circulate, e.g. corners. Also keep
itawayfromobjectsthatmaypreventthefreeowofair.
Positionthedeviceatleast30cmfromlightttingsorinterior
ttingsthatmaypreventsmoke/heatreachingthedetector.
Position it at least 1 metre away from the wall. See Figure 3A.
Wall mounting, if ceiling mounting is not possible
Avoid installing the device a long way into a corner.
Position the upper edge of the smoke alarm at least 15
cm and no more than 30 cm away from the ceiling. See
Figure 3A.
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 highest point, measured horizontally, because still air
under the ridge may prevent smoke reaching the device.
See Figure 3B.

REPLACING THE BATTERIES
How often you need to replace the batteries depends
on the type of battery. However, it is a good idea to
replace batteries regularly, once a year, and ideally on a
set date.
1.Turnthesmokealarmanti-clockwisetoreleaseit

alarm also reacts to dust particles, moisture and other
particlesintheformofpollen,insects,etc.Thesearethe
most common causes of false alarms.

Vacuum clean the smoke alarm regularly – use a plastic
mouthpiece so as not to damage the electronic components.
Make sure not to position the smoke alarm in highly dusty or
dirty places. Place a “cap” over the smoke alarm or remove
it completely if you are carrying out renovation work in your
home.
Draughts, dust and air ows. False alarms can be caused
by positioning the smoke alarm too close to doors, windows,

SOURCE OF ERROR MEASURE
Steam and moisture. False alarms can be triggered if the
smoke alarm is positioned too close to bathrooms or laundry
rooms, or in other places where the ambient humidity is high.
Position the smoke alarm at least 2 metres from bathrooms,
laundry rooms and other places where the ambient humidity
is high.
Dust and dirt.Astheairowsfreelythroughthedetection
chamber, the smoke alarm will attract a fair amount of dust and
pollenparticles.Thiscantriggerfalsealarms.Itcanalsomake
the smoke alarm more sensitive, which can likewise result in
false alarms.
Vacuum clean the smoke alarm regularly – use a plastic
mouthpiece so as not to damage the electronic components.
Make sure not to position the smoke alarm in highly dusty or
dirty places. Place a “cap” over the smoke alarm or remove
it completely if you are carrying out renovation work in your
home.
Draughts, dust and air ows. False alarms can be caused
by positioning the smoke alarm too close to doors, windows,
ventilation systems, fans, air ducts, heat pumps and the like.
Thiscancausedustparticlestowhirlupandintothedetection
chamber.
Do not install smoke alarms in draughty places or close to
windows and doors, ventilation units, fans, air ducts, heat
pumps and the like. Find a more appropriate place for the
smokealarm,fartherawayfromdraughtsandairows.
Temperature variations can cause condensation to form in
the detection chamber. For example, if the smoke alarm is
placed in a room where windows are opened for ventilation in
the winter, close to exits, balcony doors or other places where
the temperature alternates between hot and cold.
Avoid installing smoke alarms in rooms where the
temperature changes rapidly, or close to doors and windows
that are often opened and closed. Move the smoke alarm to
a place witha more even, stable temperature.
Inappropriate placement.Incorrectplacementinanunstable

COMMON CAUSES OF FALSE ALARMS AND
HOW TO AVOID THEM
A smoke alarm detects and reacts to smoke particles
intheair.Thesmokeparticlestriggerthealarm’saudio
signal. However, this sensitivity does mean that the smoke
alarm also reacts to dust particles, moisture and other
particlesintheformofpollen,insects,etc.Thesearethe
most common causes of false alarms.
SMOKE ALARM WARRANTY
Thissmokealarmcomeswithalimited3-yearwarranty
against manufacturing defects. (Valid from the date
ofpurchase).Thebatteriesarenotcoveredbythe
warranty.Thewarrantyliabilityislimitedtothevalueofa
corresponding smoke alarm. Defective smoke alarms must
be returned to the dealer together with a description of the
problem. Approved complaints will result in replacement
with a new smoke alarm of the same or a corresponding
type. When submitting a complaint, you must present a
