is non-binding and intended as a guide. The
material depends on individual local requirements.
You will need:
o Power supply: 12 V DC mains adapter
connection to a 230 V~50 Hz socket, or
12 V DC on-board power supply system.
o A crosstip screwdriver for installation with
the fastening screws.
o A pen to mark the installation points.
o A drill for the mounting holes.
o An in-line fuse holder (250 mA/slow-acting
fuse) – only for connection to on-board
supply system.
Selecting the installation position
When there is an escape of gas, the gas
detector can only give the alarm if it is
reached by the escaping gas. Anything which
prevents gas from entering the alarm housing
can result in the alarm being given only after a
delay or not at all. Select an installation posi-
tion that is as close as possible to the gas
appliance, but not farther away than 4 m (liq-
uefied petroleum gases) or 6 m (methane)
(see Fig. C). Make sure that the mains socket
for connection of the 12 V DC mains adapter
is located max. 2 m away from the installation
position of the gas alarm. To detect town, nat-
ural and methane gas, the installation position
should be as far up on the wall as possible.
The gas alarm should be mounted 15-30 cm
below the room ceiling and must be higher than
the highest door or window opening. The gases
in question are lighter than air and therefore rise.
To detect propane and butane gas, choose a
low installation position on the wall. It should
be 15-30 cm above the floor. Liquid gases are
heavier than air and therefore sink to the floor
and spread from there.
Do not under any circumstances install the
gas alarm in any of the following places:
o Outside buildings, e.g. to guard open
crates of bottled gas.
o Enclosed spaces (e.g. in cupboards or
behind curtains), which could prevent the
alarm from responding in the event of a
gas leak.
o Directly next to an oven.
o Directly above a washbasin or drain.
o Next to a door, window, ventilation, fan, air
conditioning unit, etc.
o Areas in which the temperature can fall
below –10 °C or rise above +50 °C or in
which air humidity can rise above 95%.
o Areas in which dust or dirt can clog the
sensor.
o Any position in which it could accidentally
get damaged or pulled down.
o Areas under the risk of explosion.
