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:

Power supply: 12 V DC mains adapter

connection to a 230 V~50 Hz socket, or

12 V DC on-board power supply system.

A crosstip screwdriver for installation with

the fastening screws.

A pen to mark the installation points.

A drill for the mounting holes.

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.

m

Do not under any circumstances install

the gas alarm in any of the following

places:

Outside buildings, e.g. to guard open

crates of bottled gas.

Enclosed spaces (e.g. in cupboards or

behind curtains), which could prevent the

alarm from responding in the event of a

gas leak.

Directly next to an oven.

Directly above a washbasin or drain.

 Nexttoadoor,window,ventilation,fan,air

conditioning unit, etc.

Areas in which the temperature can fall

below –10° C or rise above +50°C or in

which air humidity can rise above 95%.

Areas in which dust or dirt can clog the

sensor.

Any position in which it could accidentally

get damaged or pulled down.

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.

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.

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

Lead the bare cable ends (approx. 8 mm)

of the 12 V DC connecting cable

from

the 12 V DC mains adapter to the terminal

screws

in the cable guide

. The

cable guide provides strain relief.

Attach each cable end to a terminal screw

. The polarity is not important for this

connection.

12 V DC on-board power supply system

Remove the connecting cable of the mains

adapter from the terminal screws

Equip the connecting cable for the power

supply (12 V DC) in cars, caravans or

boats with a switch.

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

in the cable guide

. The

cable guide helps to prevent strain on the

connections.

Attach each cable end to a terminal screw

The polarity is not important for this con-

nection.

Important information regarding on-board

operation: only one power supply may be

connected to the terminal screws

even if the mains adapter is not plugged

in. The mains adapter will be damaged if
