3. INTENDED USE
The GAS ALARM GX-A1-CO is a combination of ext. CO sensor and control unit for carbon
monoxide and warns of CO concentrations that were specified in DIN EN 50291 (CO in
living spaces). This monitoring system is therefore set to be very sensitive in accordance
with its purpose. This CO gas warning device may only be used together with the enclosed
CO sensor.
An LCD display constantly informs you about the operating status. The alarm signal occurs
acoustically and optically, both on the control unit and on the sensor itself. At the same time,
a potential-free relay is switched to, for example, lock the gas supply line with a solenoid
shut-off valve so that no more gas is used in the event of a leak in the gas line or in the gas
boiler can emerge. Another relay switches if the control unit itself detects technical faults. The
device must not be used in potentially explosive areas. Control unit and sensor are matched
to one another.
Only operate the two devices together and exclusively in dry interior rooms with similar uses,
e.g. in living rooms, shops, shops, offices, in dust-free workshops, seminar rooms and much
more.
The device is not approved for any use other than that described above.
4. ASSEMBLY INSTRUCTIONS
4.1 Wall mounting GX-A1 +
The four housing screws must be loosened for wall mounting. Then the front panel is re-
moved and, if necessary, the ribbon cable is pulled off the connector. The lower shell of the
housing can now be mounted on a wall
(Mounting material is included).
Important! The connection cables that lead to the gas detector
must be permanently installed as surface-mounted cables.
The GAS ALARM GX-A1 + and the sensor may only be used in dry
Indoor rooms with similar use are installed,
so that the warning device functions properly.
4.2 Sensor installation
The sensor to be connected only detects carbon monoxide CO. While CO, which escapes
from gas boilers or similar, is initially heated and rises to the top, CO, which is at the same
temperature as the room air, is slightly heavier than air and sinks to the floor. In the DIN
Norm speaks of the average nose height of the people who are regularly in the room. If in
doubt, ask your master chimney sweeper.
Be sure to pay attention to the mounting height!
Include your master chimney sweeper in your planning
and we can advise you on the optimal installation height.
The assembly must be carried out by a qualified specialist.
Please note the five safety rules!
