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

Operating Manual: PX-1C - Smoke Alarm Device with Radio Link
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.
