Contamination message

the readjustment of the detection elec-
tronics is no longer possible due to heavy
soiling. During the contamination message,
a double tone will sound every 90 seconds
(see chapter 17 “Alarm and alert tones“ on
page 78). Proceed as follows:
(1)
Press testing/stop button to turn
off the contamination message for
24 hours.
(2)
Replace the device.
Alarm without cause of fire
An alarm without fire is triggered under
the following circumstances:
•
Regular development of dust
in residential areas that are
promoted by textiles (e.g., carpets,
clothing, blankets and pillows)
•
Pollen, construction,
grinding or fine dust
•
Insects or micro-organisms
that have overcome the insect
barriers of the device
•
Strong cooking, water and/or
frying fumes and room, fragrance
and insect repellent sprays
•
Extreme temperature fluctuations
or very strong electromagnetic
radiation in close proximity
influence the device
Cigarette smoke only trig-
gers an alarm when it is in
the immediate vicinity and
in higher concentration.
You can take the following corrective
measures:
f
Stop the alarm (see chapter 11.1
f
Ensure that there is adequate venti-
lation at the installation location.
f
Carefully and regularly clean the
device, e.g. using a vacuum cleaner.

Inform neighbours about an alarm
without a cause of fire, so that they
do not falsely inform the fire brigade.
