alarm. Read through the whole folder before installing
it, and keep the folder for future reference.
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).
CHARACTERISTICS
• Opticalsensortodetectsmoulderingres
• LED indication for Alarm and Voltage
• Warning for low battery level
• Complete with plugs and screws
• 85 dB alarm signal

• Do not remove or disconnect the battery to stop false
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-
family homes.
• This smoke alarm is not suitable for use in buildings that
are not used for residential purposes. The smoke alarm
is no substitute for a full alarm system that is required
by law or by the fire authorities.
• The smoke alarm detects combustion particles in the air
(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.
