Installation

c Danger: make sure that the gas alarm is

not powered during installation.

o

Remove the mounting ﬁxture

h

from the

rear side of the casing

g

by sliding it

downwards (see Fig. B).

o

Mark the installation position with the aid

of the two round holes in the mounting

ﬁxture

h

.

o

Install the mounting ﬁxture

h

in the cho-

sen and marked position using the fas-

tening screws and wall plugs supplied

with the gas alarm.

o

Push the gas alarm ﬂush from above onto

the mounting ﬁxture

h

.

Operation

Once the power supply has been connected

properly, an automatic self-test is carried out:

the gas alarm emits several loud alarm signals

and at the same time the red ALARM LED

c

on the front of the casing

a

ﬂashes. The green

POWER LED

then lights up to indicate that

the device is ready for operation (see Fig. A)

12 V DC mains adapter

Switching on:

o

Plug the mains adapter directly and fully

into a 230 V~50 Hz mains socket. Do not

use any type of tabletop socket or exten-

sion cable, since these can cause inter-

ruptions in the power supply.

Switching off:

o

Remove the mains adapter from the

mains socket.

12 V DC on-board supply system

Switching on:

o

Switch the 12 V DC on-board power supply

on.

Switching off:

o

Switch the 12 V DC on-board power supply

off.

Alarm in the event of a gas leak

The gas alarm detects a gas leak with the

sensor. If the concentration of gas at the sensor

exceeds the pre-set sensitivity threshold on

the gas alarm, the alarm responds: the red

ALARM LED

c

ﬂashes and the loud alarm

signal is emitted.

The alarm continues until the gas concentration

falls back to below the pre-set sensitivity level.

Follow the instructions in the section

„What to do in the event of a gas leak“

Function test

Use a gas lighter to test the function of the gas

alarm.

o

Allow gas to escape from the gas lighter

directly next to the lower or side sensor

opening

k

.

o

Make sure that there is no ﬂame on the

lighter. The gas alarm detects the gas

with the sensor. If the gas concentration

at the sensor exceeds the pre-set sensi-

tivity threshold, the alarm responds: the

red ALARM LED

c

ﬂashes and the loud

alarm signal is emitted.

o

Do not allow any more gas to escape

from the lighter once the gas alarm has

responded.

The alarm continues until the gas con-

centration falls back to below the pre-set

sensitivity level.

Fault indicator

The device carries out a self-checking routine

for your safety. Possible errors are displayed

by the FAULT LED

e

ﬂashing and a coincident

beeping noise from the device.

This fault indicator may also be triggered by

the gas alarm’s surroundings or by an internal

problem inside the device.

If a fault is indicated you must check ﬁrst:

o

Whether the ambient temperature is out-

side the speciﬁed range (-10° C to +40° C).

o

Whether chemicals present in the air may

have cause the fault, e.g. a high concen-

tration of acid or alcohol. If this cannot be

conﬁrmed, then try the device in another

room. If no fault is indicated there then

the problem lies in the surroundings.

If the fault indicator is still active then the

problem lies within the device itself:

o

The gas alarm has suffered internal damage.

o

The gas alarm can be used for approxi-

mately 5 years.

Then it should be replaced.
