gas alarm.
Initial operation
Preparation and materials required:
The stated materials are not included in the
delivery scope. The information provided here
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 position that is as close as
possible to the gas appliance, but not farther
away than 4 m (liquefied 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, natural and methane gas, the instal-
lation 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.
c 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.
Power supply
c Danger! Ensure that no voltage is present
when connecting to the power supply and
during installation.
o Only operate the gas alarm connected to
a 12 V DC power supply. Connect it either
with the 12 V DC mains adapter (included
in the delivery scope) or to a 12 V DC on-
board power supply system of a car, cara-
van or boat.
o Check before connecting the 12 V DC
adapter to the mains that the electricity
supply to the device is protected by the
appropriate fuse or trip in accordance
with the applicable regulations.
12 V DC mains adapter
o Lead the bare cable ends (approx. 8 mm)
of the 12 V DC connecting cable f from
the 12 V DC mains adapter to the terminal
screws
i in the cable guide j . The
cable guide provides strain relief.
o Attach each cable end to a terminal screw
i . The polarity is not important for this
connection.
12 V DC on-board power supply system
o Remove the connecting cable of the mains
adapter from the terminal screws i .
o Equip the connecting cable for the power
supply (12 V DC) in cars, caravans or
boats with a switch.
o Lead the bare cable ends (approx. 8 mm)
of the 12 V DC connecting cable of the
12 V DC power source to the terminal
screws
i in the cable guide j . The
cable guide helps to prevent strain on the
connections.
o Attach each cable end to a terminal screw i .
The polarity is not important for this con-
nection.
o Important information regarding on-board
operation: only one power supply may be
connected to the terminal screws
i ,
even if the mains adapter is not plugged
in. The mains adapter will be damaged if
