of the device, but also onto the surfaces of
the optical sensor components of the smoke
alarm device. Particularly there, the adhesion
of condensates leads to the premature impair-
ment 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 particularly 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 battery
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 tem-
perature 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 temper-
atures 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:
The excessive load on the battery capacity due
to the frequent triggering of signal tones (more
than once a month) can due to the associated
battery-consumption lead to premature con-
sumption of the battery capacity, and the con-
comitant loss of any relevant warranty claims.
Please verify on your part, prior to asserting
a warranty claim, whether at least one of the
above grounds for warranty exclusion is given,
and you should moreover in the case of the
assertion of a warranty claim also ensure that
there are sufficient technical capabilities availa-
ble that can be used to determine, if the smoke
alarm device was really treated as intended
and therefore whether the warranty claim is
as such justified or unjustified.
