This gas alarm is design
ed for the use in private apartments, caravans, and holiday homes. It is not to be
used in hazardous locations and is not suitable as a measure of primary explosion proofness within the
meaning of the guidelines of the employers’ liability insurance associ
ation.

For these gasses, the Gas Alarm should be mounted near (approx. 20 cm) above the floor and also near
the gas appliances, if possible. Escaping liquefied gas is heavier than air, therefore it
descends to the floor
and spreads there.
These gasses are lighter than air and therefore rise upwards. Mounting of the device on the wall, at 15
-
30 cm below the highest point of the ceiling.
The following places are
not suitable:
Directly at an appliance operated by gas
TECHNICAL DATA
PLACEMENT

−
In closed compartments and cupboards or in a place where a door, wall or divider impedes the gas
flow to the Gas Alarm
Places where the gas flow cannot reach the Gas Alarm on the grounds of draught
and wind
Rooms in which aerosols (hair sprays, deodorants, etc.) or ammoniac are used (e. g. bathrooms)
The appliance is fixed to the wall by means of two screws (see ill.) Please heed the mou
nting height
absolutely according to the chapter “Placement”. In case of the model 230 V, take into account the cable
length to the socket.
This appliance is delivered with a service cable and Euro p
lug. For this device, a Euro
socket with 230V AC (alternating current) has to be used.
Only use a 12
-
V
-
DC power supply. As a rule, this will be a power pack, a car or an on
-
board battery respectively or an alarm main frame, for example.
For
security reasons, the Gas Alarm is equipped with an electronic voltage regulator. This regulator will
equalize voltage fluctuations due to the standard tolerance of on
-
board battery or a power consumption’s
fluctuating violently. The tolerance zone is 12 V
olts DC
20 %. Please take into account the fact that in
case of many cheap transformers, there are big tolerance variations, especially fluctuating upwards. If
they exceed the admissible tolerance zone, there is the danger of both the voltage regulator an
d the
electronics of the device being destroyed.
For the connection, a service cable with wire marking be used. The cover of the right terminal
strip is removed by means of a small screwdriver, and service cables are guided through the marked
o
penings at the lower side of the appliance. Connect the wires of the service cable to the correct terminals
+12 V DC and
12 V DC. Refit the cover of the terminal strip.
In addition to the built
-
in siren, the Gas Alarm offers you sever
al output signals for the drive of other
signal proving devices or other appliances.
The terminals are under the left cover (see ill.). By of a small screwdriver, the cover can b
e
detached. The connecting lines are guided through the openings at the lower side of the housing
and screwed on to the terminal. Thereupon, the cover of the terminal strip is fitted on again.
There are two possibilities for signal transmission. In
both cases, the signal is activated during the
duration of the alarm:
1. Switched 12

2. Make

break contact free of potential. These contacts are used for the connection to e. g. an
alarm system, telephone dialling device, pilot light, the like. The relay contacts can be loaded with
max. 5 A (in case of 230 V
AC or 30 V DC).
A make contact (normally open
closes in case of alarm) is connected to the terminals N/O und COM.
A break contact (normally closed
opens in case of alarm) is connected to the terminals N/C und
COM.
The G
as Alarm is equipped with a green equipment
-
on indicator lamp (LED). As soon as the device is
connected electrically, the equipment
-
on indicator lamp “Operation” lights up.
After the connection, the sensor of the alarm needs a hort heat
ing
-
up time until it attains its operatability.
During the heating
-
up time, the lamp “Alarm“ shows red. At the same time, the acoustical signal (siren)
whines.
When the operatability is reached (approx. 1
–
4 minutes), the red lamp “Alarm” goes out and the
whining sound dies away.
With that, the appliance is operable.
The electrical working order is indicated by means of green light emitting diode. For the operation
checkout of the Gas Alarm S/2
-
P, use a gas lighter. Open it near the sensor openi
ng
the flame
burning. The device will immediately signal alarm by lighting up the red light emitting diode and the
whining of the siren. The whining will die away and the alarm lamp will go out as soon as the
concentration of gas has volatilized.
If the gas concentration at the device exceeds the sensitivity threshold adjusted by the factory, the device
will immediately signal alarm through the red alarm lamp and the siren
–
loudness level approx. 85 dB
(A)/3 m. A signal will be passed on to
other connected indicators or appliances, if necessary.
In this case, open all windows and doors without delay, avoid sparking (do not activate any electrical
switches), switch off all devices o
perated by gas and put out all open lighting points, make children and
sleeping persons leave the building or caravan immediately.
Try immediately to find out the cause of the alarm and remedy or neutralize the mistake.
Have your gas system checked and r
epaired by a specialist!
Correspondingly to its purpose, the Gas Alarm is adjusted to be very sensitive. Therefore, the sensor of
the system also responds to other gaseous media. The use of aerosolen (propellant in spray cans, etc.) but
also
thick tobacco smoke can lead to a false alarm.
The housing of the Gas Alarm can be cleaned with a duster or a slightly damp cloth. Please blow out the
opening of the sensor slightly from time to time
–
depending on the environmental condit
ions. The Gas
Alerter must never be sprayed with water. The warning containing sensitive electronic

If you open the housing, the warranty claim will expire.
