1. Safety instructions
Note: The alarm sound is very noisy! Your hearing can be damaged if you are exposed to the
loud alarm sound over a longer period of time!
Please do not paint over the smoke alarm detector with paint or similar!
Do not install the detector in difficult to access areas! The detector must be checked regularly
for its function!
Caution: Never test the smoke alarm detector with an open flame, e.g. by a candle or a
lighter! This will damage the built-in sensor!
Get rid of the smoke alarms regularly (at least every six months) of dust and other deposits of
dirt! Please use a paint brush or a slightly cloth moistened with water. In dusty conditions, the
smoke alarm detector should be cleaned monthly.
This product is only suited for indoor-use and not for outdoor-use. Protect it against humidity
and moisture, splashing or dripping!
Damaged smoke alarm detectors must be replaced immediately!
2. Mounting location in rooms of the smoke alarm detectors
2.1 Smoke alarm detectors should be installed in the following rooms:
Bedrooms: If several bedrooms are in the house, then the attachment of smoke alarm
detectors in each bedroom are advised.
Corridors and stairways: Because stairwells easily serve as chimneys for smoke and fire, they
contribute to the further spreading. Therefore it is recommended to install on each floor at
least one smoke alarm detector!
Living and working rooms as well as storage areas.
Cellar and attic space: With the attic space a distance should be kept to the roof point of at
least 50 cm (see Figure 1).
Figure 1: Mounting the smoke alarm detector on the roof slope
Rooms are equipped with electrical appliances.
For rooms that have sloping ceilings, the following must be considered: With the assembly a
distance of from 50 to 100 cm to the roof point must be kept.
If the horizontal ceiling is less than 1 m wide, then the smoke alarm detector must be installed in
rooms with sloping ceilings as shown in Figure 2. If the ceiling is greater than 1m, then the smoke
alarm detector is placed on the horizontal ceiling.

Figure 2: Mounting the smoke alarm detector on the ceiling ≤ 1m
Note: If you are unsure about the mounting of the smoke alarm detector in your rooms, please
advised by a qualified electrician!
The smoke alarm detector must be installed on the ceiling in the middle of the room, because
smoke rises to the ceiling of the room and spread horizontally. The smoke alarm detector should
be placed possible so that this is at least 50cm from the side wall and 61cm mounted away from
the corner of the room (see Figure 3).
Figure 3: Mounting the smoke alarm detector on the ceiling
On ceiling beams, which are thicker than 20 cm, no installation of smoke alarm detector
should be done. A minimum distance of 50 cm is urgently recommended.
The smoke alarm detector should be mounted at least 50 cm away from lamps and
fluorescent lamps.
An installation height of 6m maximum should not be exceeded. If the installation height is
more than 6m, the smoke alarm detector must be installed on several levels.
The smoke alarm detector can supervise a maximum area of 60m².
The maximum distance of smoke alarm detectors in extensive corridors can be up to 15 m. To
the end side of corridors the smoke alarm detectors should be applied in the distance of
maximum 7.5 m.
In small corridors and rooms which are not wider than 1m, the smoke alarm detector must be
mounted in the middle of the ceiling.

5
2.2 Rooms where no smoke alarm detector should be installed
Rooms which have a high air humidity - for example in the bathroom.
In garages or kitchens. A smoke alarm detector in the kitchen should only be installed, if the
distance to the stove is at least 4m.
Smoke alarm detectors should not be installed close to heaters, heating-, cooling- and
ventilation-shafts. Also, they may not be mounted on open fires or fireplaces.
In very dusty rooms.
With A-shaped roofs the smoke detectors may not be mounted at the highest point.
Rooms having a room temperature of below 5 ° C or above 45 ° C.
In caravan or similar rooms. In these living areas, the attachment to the inside of parts are
advised. The air in the upper part of these areas as well as the ceiling is strongly warmed up
by intense solar irradiation. This can result that the strongly warmed up air keeps the smoke
from reaching to the smoke alarm detector.
3. Installation and startup
Before starting up this product, please check for external damage. In case of visible external
damage we immediately dis-advise the start-up of this product! Please remove all packaging
material of this product before the first start-up.
Disconnect the mounting base by turning it counterclockwise from the case.
Break the safety pin carefully out of the mounting base (see Figure 4). To do this, take a
screwdriver for help.
You can attach the mounting base with the included screws to the ceiling. The drill-holes are
shownin figure 4.
Figure 4: Mounting base
1. Hold the mounting base to this position on the ceiling, where you want to mount the smoke
alarm detector. Draw with a pencil the holes for the bores to the ceiling.
2. Then drill two holes (Ø 5mm).
3. Now take the two in the scope of delivery supplied dowels and put them in the bores.

3.1 Activation of the smoke alarm detector
To activate the smoke alarm detector, hold down the TEST button for approx. 3s until the red
LED lights up. While the LED is red, release the TEST button. The smoke alarm is now
activated.
3.2 Temporary muting the Alarm
In a false alarm, which was not caused by a fire, the alarm can be switch off for about 10
minutes. However you must absolutely make sure that the alarm was not activated by a fire,
but rather e.g, by strong smoke during the cooking or by strong smoking of cigarettes or cigars
in small rooms! To temporarily turn off the alarm, press the TEST button. Then open doors and
windows to clean the air. Should the air still have a high number of combustion particles after
10 minutes, the alarm sounds again. By pressing the test button, the mute function can be
repeated as often as desired. The mute function can be simply deactivated by pressing again
the start button. At an excessively large amounts of smoke, this function is not adjustable.

3.3 Function Control of the smoke alarm detector
The TEST button (see Figure 5) is used to check the function of the smoke alarm detector.
After pressing the key a very loud alarm will sound! Keep the smoke alarm detector at least an
arm's length away from your body while pressing the TEST button. The activation of the alarm
takes place after approximately 4 seconds of pressing the button Afterwards the LED starts
flashing and the alarm sounds. In this case the function of the electronics, the alarm device of
the smoke detector and the battery is checked. After releasing the TEST button, the alarm will
turn off automatically.
Attention: Test the smoke alarm detector weekly to its function by pressing the test button. It
even beeps once and the alarm stops automatically after releasing the TEST button.
3.4 Recurrent self-test of the smoke alarm detector on its function
The smoke detector performs every 30-40 seconds a self-test. You can see this by a short
blink of the LED.
Note: In case of improper function of the smoke alarm detector, please contact the
manufacturer!
4. Technical Data

5. Information to the re-built battery
This heat detector is equipped with a non-replaceable lithium battery. The battery will last
approximately 10 years during normal operation. Should the battery will be weaker, every 40
seconds a clearly perceptible signal will be sent out from the smoke alarm detector. This signal is
audibly at least 30 days. As soon as the beep sounds, the smoke alarm detector must be
replaced.Batteries should never be exposed to extreme heat (for example, by strong sunlight or
fire). Never throw batteries into the fire. Risk of explosion!
6. Reasons for triggering a false alarm
The following may be causes of a false alarm:
Water and kitchen steam

8
high air humidity
dust
Strong drafts etc.
Usually the smoke of cigarettes does not trigger the alarm. If the alarm still be triggered, please
make sure that not a fire has activated the smoke alarm detector! If no fire is detected in one of
the rooms, you can set the alarm of the smoke detector temporarily mute (see chapter: "3.1
Temporary muting of the alarm").
7. Behavior in case of fire
The installation of a heat or smoke alarm detector is only one of many fire protection measures.
Other fire protection measures are e.g. the provision of a fire extinguisher or a fire blanket.
Another measure is the creation of an escape plan and the subsequent discussion with your
roommates or your family.
If the fire cannot be extinguished with a fire extinguisher or a fire blanket by yourself, then leave
the house immediately! Do not waste time to put clothes on or by transportation of personal
objects - because every second counts!
After leaving the house please inform the fire department immediately!
When leaving the burning room, please check first the surface of the door to its temperature.
Should the door be hot or under the door smoke rising up, do not open the door! If possibly please
use another door or a window to escape from the room. If the surface of the door is cold, then
brace yourselves with the shoulder against the door and open it a small gap. Be always careful
and ready to slam the door quickly, if heat or produced penetrates from the next door.
With strong production of smoke please keep close to the ground and breathe - if possibly -
through a cloth. Better still by a damp cloth!
You may enter the house again only after release or permission of the fire brigade!
8. Maintenance and cleaning
This device is maintenance free. Please remove the housing regularly from dirt, dust or spider
webs! For this, use the best vacuum cleaner with soft suction brush or a soft cleaning cloth.
Ensure that the housing and the air slots are free from contamination at all times, in order to
ensure proper functioning.
Note: Never open the housing to clean the unit from the inside. This can impair the functionality
and the warranty guarantee will be extinguished!
