Especially nicotine and grease condensate are
not only deposited onto the exterior surface
of the device, but also onto the surfaces of
the optical sensor components of the smoke
alarm device. Particularly there, the adhe-
sion of condensates leads to the premature
impairment of the optical properties of the
sensor components, which the smoke alarm
device can only compensate by means of
autonomous recalibration within the physical
limits.
Moisture damage/corrosion:
If the smoke alarm device, and particular-
ly its electronics, is damaged by moisture of
any kind, it leads to the loss of all warranty
claims.
Moisture is not only the exposure to a fluid,
but also the constant exposure of the device
to excessive air humidity (> 70%), because
exposure to excessive humidity (e.g. steam/
cooking vapor) drains the battery on the one
hand, thus significantly shortening the bat-
tery life. On the other hand, fluids and high
humidity can damage the electronics of the
smoke alarm device by causing corrosion.
Thermal damage:
If the smoke alarm device is exposed to
a temperature below 0°C or above 70°C
briefly or constantly, it leads to the loss of all
warranty claims. In particular, no warranty is
given for devices that were exposed to high
temperatures and flue gases during a fire.
Damage to the device resulting from frost/
cold, are not covered by the warranty, the
same as heat damage.
Excessive load on the battery:
Insofar as the wireless smoke detector is
operated in the vicinity of other electronic,
radio-based equipment, and the minimum
distance between such devices and the
wireless smoke detector, which is specified
in this user manual is regularly or perma-
nently exceeded, this can lead to premature
consumption of the battery capacity. Such,
improper use of the wireless smoke detector
is coupled with the loss of any relevant war-
ranty service.
Also, the excessive load on the battery ca-
pacity due to the frequent triggering of signal
tones (more than once a month) or the re-
peated change/set up a wireless group, more
