Alarm
The sensor of the gas alarm registers escaping gas. The device emits an alarm if the
sensor registers a gas concentration in excess of the sensitivity threshold set in the
factory: An evenly pulsing signal tone sounds and the red ALARM LED flashes. A signal
is fed to any other connected devices.
The alarm continues until the gas concentration falls below the preset sensitivity
threshold.
Do not disconnect the gas alarm in the event of an alarm!
What to do in the event of an alarm
Remain calm in the event of an alarm or if you smell gas. Carry out the following
measures in the sequence that makes the most sense to you:
Extinguish all open flames including all smokers' articles such as cigarettes, cigars,
pipes, matches, lighters, etc.
Turn off all gas applications.
Do not turn electrical devices on or off.
Do not, under any circumstances, disconnect the gas alarm from the power supply.
Interrupt the gas supply at the main shutoff valve or at the cylinder or storage
tank valve.
Open doors and windows to increase ventilation.
Do not use telephones in the building in which the presence of gas is suspected.
If the alarm continues and the source of the escaping gas is not obvious or cannot be
corrected, the building must be cleared and the gas supplier or the 24-hour emergency
service IMMEDIATELY informed so that the gas installation can be checked, secured
and repaired.
If the alarm stops and the cause of the alarm has been established and corrected
(e.g. the gas valve was open and the burner not in operation), the main gas supply
can be opened again once the escaping of gas has been stopped and it is sure that
all consumers have been shut down.
Please also proceed as outlined above when using the device's switching output to
close a solenoid valve in the gas line.
The gas alarm issues an output signal which can be used to trigger auxiliary equipment
such as a ventilation fan or a gas shutoff valve. Once it has been triggered, it may be
necessary to manually reset the equipment. The equipment should not be reset until
the source of the gas has been identified and the fault has been corrected. In the case
of gas-operated devices, if the gas supply was cut off by closing the solenoid valve, it
may only be opened by a qualified plumbing contractor or a specialist from the gas
supplier.
