tive to replace the device during this
period!
POSSIBLE CAUSES FOR A FALSE
ALARM
• One or more of the following sub-
stances have entered directly into the
device: heavy vapor from cooking, boil-
ing or frying; air freshener, fragrance
or insect spray; pollen; dust from
construction or sanding; fine dust.
• Extreme temperature fluctuations or
very strong electro-magnetic radiation
in the direct vicinity of the smoke
alarm device have an impact on the
device.
• Cigarette smoke only sets off the
alarm when smoke enters the device
either directly from the immediate
vicinity or due to extremely high
concentrations.
To avoid a false alarm from the smoke
intake fins (Fig. 1c) remain completely
free of foreign objects.
If the acoustic signal is not emitted
during alarm testing, then the device
has to be replaced.
LOW BATTERY SIGNAL/
CONTAMINATION SIGNAL
When a short, single tone (beep) is
emitted every 90 seconds, the bat-
tery supply is depleted.
When a short, double tone (beep-
beep) is emitted every 90 seconds,
the device can no longer automati-
cally compensate the soiling of its
optics.
Both of these fault signals can be
temporarily deactivated for 24 hours
by pressing the test/stop button (Fig.
1d).
The smoke alarm device is capa-
ble of emitting either of the two
above-mentioned fault signals for a
maximum of 60 days. It is impera-
alarm device, the device should be
protected against all of the environ-
mental effects mentioned here.
• One or more very small insects
or other very small organisms have
gotten past the insect barriers of the
device. Carefully clean the device with
a vacuum cleaner to remedy this.
When cooking or generally when
heavy steam arises near the smoke
alarm device, always ventilate the
rooms well. A false alarm can be
turned off or prevented by gently
pressing the test/stop button (Fig. 1d)
and ventilating the rooms well.
Please inform your neighbors in case
of a false alarm, so that the fire depart-
ment is not unnecessarily alerted.
GENERAL SAFETYINFORMATION
Smoke alarm devices help to spot fires
early but can neither extinguish fires,
prevent the start of fires, nor alert the
fire department.
Smoke alarm devices emit an alarm
when there is a hazard due to fumes
and to call your attention to this hazard.
Despite taking the greatest care in the
production of smoke alarm devices,
there is the possibility of malfunction, in
which case the device may not be able
to quickly alert or to alert at all to the
possible start of a fire. Always observe
the usual precautionary measures for
dealing with fire, combustible materials
and technical equipment!
This is a self-contained device. Opening
or modifying the device results not only
in loss of the guarantee but also has the
consequence that the device can and
must no longer be used as intended.
Please do not ever open the device due
the risk of injury!
Changing the battery is neither re-
quired and nor even possible.
