1.8 Warranty exclusion criteria
Soiling
Dust deposits and insect infestation in
the measuring system of the device are
not covered under warranty. Also smoke
alarms or warning signals associated with
such forms of soiling do not indicate a mal-
function of the device, but only show a lack
of care, cleaning and maintenance thereof.
Physical / mechanical damage
If the device has been damaged,
e.g. the housing has been broken or the
device has been opened, any warranty
claim shall be forfeited.
The same shall apply to subjecting the de-
vice to any form of brute force, which does
not cause a physical damage to the device,
but causes a damage inside the housing
(e.g. of electronics).
Contamination
If the device is externally and / or internal-
ly contaminated by deposits (excessively

contaminated), any warranty claim shall
be forfeited. Paint and similar substances
on the surface of the device and within
the housing / measurement system of the
device shall be deemed contamination.
Decoration / painting limited to the re-
lease testing / stop button (smoke alarm
device cover) shall be excluded from a
warranty exclusion!
In addition, build-up of fire residues
(e.g. soot), as well as nicotine and grease
deposits, which have caused a readily
detectable discolouration of the device,
are categorized as contamination, which
means the loss of any warranty claims.
Especially nicotine and grease condensates
do not only gather on the outer surface
of the device, but also accumulate on the
surfaces of the optical measuring compo-
nents. Particularly there, the adhesion of
condensates leads to premature deteri-
oration of the optical properties of the
measurement components, which the de-
vice can compensate through autonomous
recalibration only within its physical limits.
Moisture damage / corrosion
If the device, and in particular its elec-
tronics, are damaged by moisture of any
kind, any warranty claim shall be forfeited.
Moisture thus is not only the exposure to
fluid, but also regular, above-average ex-
posure of the device to humidity (> 70%).
Due to the effect of excessive humidity
(e.g., steam / roasting fumes), the battery
of the device is discharged above average,
and the battery life is shortened consid-
erably. Also, liquids and high humidity can
damage the electronics of the device by
causing corrosion.
Thermal damage
If the device has been exposed temporari-
ly or permanently to a temperature below
0° C or above 70° C, any warranty claim
shall be forfeited. In particular, no warranty
shall be given for devices that were ex-
posed to high temperatures and fumes in
a fire. Damage to the device as a result of
frost / cold, as well as heat damage, shall
not be covered by the warranty.

Excessive load on the battery
If the smoke alarm device is operated
in the vicinity of other electronic, ra-
dio-based devices, while the minimum
distance between such devices and the
smoke alarm device named in this manual
is exceeded regularly or permanently, this
can lead to premature battery consump-
tion. Such improper use of the device shall
forfeit any warranty claim.
Excessive load on the battery capaci-
ty through frequent triggering of alarm
tones (more than once a month),
or repeated changing / setting up of
a radio group more than four times
in 12 years, and repeated triggering of
a radio group alarm signal more than
four times in 12 years, for more than
15 minutes each time, may lead to prema-
ture consumption of the battery capacity
due to the related battery consumption
and to the loss of any warranty claims
