Figure 2: Mounting the radio heat detector on the ceiling ≤ 1m
Note: If you are unsure about the mounting of the radio heat detector in your rooms, please
advised by a qualified electrician!
The radio heat detector must be installed on the ceiling in the middle of the room, because heat
rises to the ceiling of the room and spread horizontally. The radio heat detector should be placed
possible so that this is at least 50cm from the side wall and 60cm mounted away from the corner
of the room. If you attach the radio heat detector to the wall, attach it approx. 30cm from the
ceiling (see Figure 3).
Figure 3: Mounting the radio heat detector on the ceiling or wall
On ceiling beams, which are thicker than 20 cm, no installation of radio heat detector should
be done. A minimum distance of 50 cm is urgently recommended.
The radio heat 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 radio heat detector must be installed on several levels.
The radio heat detector can supervise a maximum area of 60m².
The maximum distance of radio heat detectors in extensive corridors can be up to 15 m. To
the end side of corridors the radio heat detectors should be applied in the distance of
maximum 7. 5 m.
In small corridors and rooms which are not wider than 1m, the radio heat detector must be
mounted in the middle of the ceiling.
2.2 Rooms where no radio heat detector should be installed
A radio heat detector in the kitchen should only be installed, if the distance to the stove is at
least 4m.
Radio heat detectors should not be installed close to heaters, heating-, cooling- and
ventilation-shafts. Also, they may not be mounted on open fires or fireplaces.

3.2 Function Control of the radio heat detector
To check the function, press and hold the TEST button. After pressing the key a very loud alarm
will sound! Keep the radio heat detector at least an arm's length away from your body while
pressing the TEST button. The alarm sounds at regular intervals 3 times in a row while the LED
flashed. In this case the function of the electronics, the alarm device of the radio heat detector and
the battery is checked. After releasing the TEST button, the alarm will turn off automatically. If the
alarm does not sound, replace the batteries! If the alarm does not sound even after replacing the
batteries, the radio heat detector must be replaced!
Attention: Test the radio heat detector weekly to its function by pressing the TEST button.
3.3 Activation and Deactivation of the mute mode
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! To temporarily
turn off the alarm, press the TEST button. While the radio heat detector is in mute mode, the LED
will flash every 8 seconds. Then open doors and windows to cool down the room. If the room
temperature is still too high 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 heat development, this function is
not adjustable.

3.4 Recurrent self-test of the radio radio heat detector on its function
The radio heat detector performs every 32 seconds a self-test. You can see this by a short blink of
the LED.
Note: In case of improper function of the radio heat detector, please contact the manufacturer!
4. Networking
For networking, you need at least two networked devices. Each device is provided with a code by
the manufacturer. There are a total of over 60,000 encodings. If one device is connected to
another one, it will accept the code of the other. An already networked device, which is to be
connected to a new device, takes over the code of the new device. Please note that devices may
only be interlinked within an apartment or a family home! Note: Please connect only devices that
are not more than 35 meters apart! Please note that only devices from the same manufacturer can
be networked with each other!
Note: To prevent damage to your hearing, keep the device at least one arm's length away from
your body while pressing the TEST button!
1. Take a device that you want to network with another device and put it in the transmission
mode. Press the TEST button 3 times in succession. The LED lights up red for about 10
seconds continuously.
2. While the first device is in transmission mode for approximately 10 seconds (LED lights
continuously red), take another device and press the TEST button 3 times in succession. If a
short beep sounds and the LED flashes briefly, networking was successful.
3. In order to network additional devices with the first device, repeat steps 1 and 2 until all
devices are networked together.
4. Afterwards, check whether the devices are properly networked by carrying out a functional
check. Press and hold the TEST button on any networked device. If the alarm sounds on all
networked devices while you hold down the TEST button, the networking was successful. To
stop the function check, release the TEST button. The other devices stop beeping after a
maximum of one minute.
Attention: If the alarm sounds not on all devices, repeat the first two steps with the affected
device, and repeat the function check.
5. If the function check is unsuccessful again, perform a RESET (see chapter 5) of the device
and check the batteries. Then repeat the first two steps.

11.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

11
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!
12.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.
