!
As soon as the alarm signal goes off, do not let
any more gas out of the lighter.
!
The alarm mutes automatically as soon as the
gas concentration at the sensor falls below the
preset sensitivity threshold.
The function test must be carried out regularly, at least
every 4 weeks.

Service life

When operating continuously under normal ambient
conditions, the expected service life of the sensor is
approx. 5 years. Replace the gas alarm after a service
life of 5 years!
Various chemicals can damage the sensor
permanently. Do not subject the sensor to the
following substances and environments:
!
Sprays and adhesives containing silicone
!
Aggressive environments in which hydrogen
sulphides, sulphur dioxide, chlorine or hydrogen
chloride is present (cleaning agents containing
chlorine, descaler sprays, bleach)
!
Moisture and condensation
!
Salt-laden atmospheres

Fault display

The gas alarm carries out a continuous self-test.
Flashing of the yellow FAULT indictor indicates the
presence of a fault. In addition, two short signal tones
are issued per minute.
° ° ° °
The fault display can either be triggered by the
surroundings or there is a defect in the device.
Please proceed as follows if a fault is indicated:
2 short signal tones every
60 seconds, yellow FAULT
indicator flashes
!
Check whether the ambient temperature lies
outside the permissible range of -10°C to
+40°C.
!
Check whether chemicals in the ambient air or
other substances could have triggered the fault
display, such as an excessive concentration of
acid or alcohol in the air, cleaning liquids, paints,
lacquers, sprays, polishing agents, cooking
vapours or tobacco smoke. Check the gas alarm in
another room if necessary. If an alarm is not
signalled in the other room, the cause of the fault
is in the original installation site.
If the fault display continues to be active, there is
either a contamination, a defect in the device or the
gas alarm has reached the end of it's service life of
approx. 5 years. The gas alarm must be replaced in
this case!
