Function Checks - Indexa GA90 Mode D'emploi

Operation
As soon as the gas alarm has been properly connected
to the power supply, an automatic self-test is
conducted: The green POWER LED flashes during this
self-test. The self-test takes approx. 20 seconds. The
three LEDs light up briefly when the self-test has been
successfully completed. A signal horn sounds at the
same time. The green POWER LED then indicates that
the alarm is operational.
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 given 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.

Function checks

Use a gas lighter to test that the gas alarm is
functioning. Please proceed in the following steps:
!
Release gas out of the lighter directly next to the
sensor opening of the gas alarm
!
The sensor will register the escaping gas. The
device emits an alarm if the sensor registers a gas
concentration in excess of the preset sensitivity
threshold: A pulsing signal tone sounds and the
red ALARM LED flashes.
