Nexa's KD-134A smoke alarm is designed to
detect smoke particles and give an early warning
if a fire should start (assuming correct placing and
maintenance).

• Warning for low battery level
• Complete with plugs and screws
• 85 dB alarm signal

alarms. Open windows or ventilate the air around the smoke
alarm in order to stop it, and/or press the pause button.
• The smoke alarm is intended for use for use in single-

(smoke). It does not react to flames or gas.
• The smoke alarm is designed to emit an alarm signal if a
fire is developing.
• The smoke alarm should be tested every week and
replaced every ten years.
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.
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.
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.

FAULT SOURCE REMEDY
Steam and moisture. A false alarm may be triggered if the
smoke alarm is positioned to close to a bathroom, laundry
room or other areas where ambient humidity is high.
Position the smoke alarm at least 2 metres away from the
bathroom, laundry room or other locations where ambient
humidity may be high.
Dust and dirt. The smoke alarm will attract a certain amount
of dust and pollen particles as the air passes freely through the
detection chamber. This may lead to false alarms. The smoke
alarm may also become more sensitive on account of this,
which may result in unwanted alarms.
Vacuum the smoke alarm regularly, use a plastic nozzle so as
not to damage the electronics. Avoid installing smoke alarms
in locations where there is a lot of dust and dirt. Ideally, place
a “hood” over the smoke alarm or remove it entirely while you
are carrying out renovations at home.
Draughts, dust and air flows. False alarms may be caused if the
smoke alarm is placed too close to doors, windows, ventilation
systems, fans, air ducts, heat pumps and suchlike. This may
cause dust particles to fly up and into the detection chamber.
Do not install smoke alarms in draughty locations or close to
windows or doors, ventilation, fans, air ducts, heat pumps
and suchlike. Find a better location for your smoke alarm,
further away from draughts and air flows.
Temperature variations may cause condensation in the
detection chamber – if the smoke alarm is placed in a room
where windows are opened for ventilation in winter, for
example, or close to exits, balcony doors or other locations
where conditions switch between hot and cold.
Avoid installing smoke alarms in rooms where the
temperature changes rapidly or close to windows or doors
that are opened and closed frequently. Move the smoke
alarm to a location where the temperature is more consistent
and stable.
Adverse location. Positioning the smoke alarm incorrectly in
an unstable indoor environment may lead to false alarms due to
draughts, close proximity to electrical devices (EMC) and lighting.
Position smoke alarms at least 5 metres away from
fireplaces, stoves or other heaters. 2 metres away from
ventilation ducts, heat pumps and air conditioning.
1 metre away from lamps and fluorescent tubes.
COMMON CAUSES AND HOW TO AVOID
FALSE ALARMS
Smoke alarms detect and react to smoke particles in the
air.Thesesmokeparticlesarewhatcausethesmoke
alarmtosound.Thisfunctionmeansthatthesmokealarm
may also react to dust particles, moisture or other particles
intheformofpollen,insects,etc.Thesefactorsfrequently
cause false alarms.

least twice a year. Clean your smoke alarm by vacuuming
externally along the opening to the optical chamber to
remove any dust or dirt.
