Low Battery Signal / Contamination Signal; Possible Causes For An Alarm - pyrexx PX-I Notice D'utilisation, D'installation Et D'entretien

Low Battery Signal /
Contamination Signal
If the energy supply of the smoke alarm
device is low or the optical detection
system becomes so soiled that automat-
ic adjustment is no longer possible, then
the device emits a signal alerting you to
these conditions (see "Alarm and advi-
sory tones"). This gives you enough time
to replace the smoke alarm device. The
smoke alarm device is then only capable
of sounding its alarm for a maximum of
60 more days. It is imperative to replace
the device before this time elapses!
Possible causes for an
the cause
• In some rooms, there is ususally more
dust than in others. A bedroom is often
one such room. Frequently they contain
plush carpets; clothing, bed spreads and
pillows etc. are often stored in bed-
rooms and moved around a lot (e.g.
shaking).
Drafts in the rooms (e.g. open windows,
fans) can lead to small amounts of dust
accumulating in the device over time.
• One or more of the following sub-
stances have entered directly into the
device: steam and vapors from cook-
ing, boiling or frying; air freshener, fra-
grances, or insect spray; pollen; dust
• One or more very small insects or
other very small organisms have gotten
past the insect barriers of the device.
