PERIODICAL TESTING
We recommend to contact the installer at least once a year
for a general inspection.
IMPORTANT: do not use pure gas, such as a lighter directly
on the sensor since the sensor could be damaged.
OPERATING CONTROLS
After the installation it is possible to check the correct use of
the instrument by pushing for at least 2 seconds the TEST
button on the SE230K/SE233K board, or by pushing the TEST
botton for at least 25 seconds on the SE296K.
Using this method all the leds will be lighted, also the acustic
alarm will
be active, and the exit relay for a period of five seconds.
The Electrovalve if connected, has to be manual rearmed.
ELECTRICAL CONNECTION -
POWER SUPPLY
Attention: The electrical connection has to be carried out by
specialized technical staff. The detectors are power supplied
230Vac through connecting terminal 1 and 2, or 12Vdc by
connecting terminal 3 (+) and 4 (-).
CONNECTION FOR VALVE AND REMOTE
The detector furthermore by connecting terminal (5-6) active
in shut-down for an remote sensor . If the connecting terminals
(5-6)are not used, they have to be left disconnected.
WARNING
For the clining of the instrument utilize a cloth to take away the
dust from the covering. Don’t try to open or disassemble the
detector, it could cause an eletric shock and damege the product.
Note that the sensor employed has a good resistance towards
products such as sprays, detergents, alcohol, glues and paints.
However, these products could contain substances which, if in
great quantity, could interfere with the sensor and cause false
alarms. We recommend to ventilate the room where products like
these can be used. Note that the detector is not able to detect gas
leaking outside the room where it is installed, neither inside walls
or under the floor. To make gas (methane and LPG) nose
identifiable, gas is added with a particularly disturbing smelling
substance.
Small gas quantities coming out from left open cookers for some
minutes do not cause the gas detector alarm signalling even if it is
clearly nose perceptible; in fact the quantity of gas presents in the
environment can be under the alarm threshold. Please remember
that the gas detector cannot work without power supply.

WARNING!
In case of alarm:
1) Turn off all naked flames.
2) Close the gas supply cock or L.P.G. container.
3) Do not turn lights on or off; do not use any electrical appliance
4) Open doors and windows to increase ventilation.
If the alarm stops, it is necessary to find and deal with the
cause.
If the alarm continues and the cause is not identificable and
cannot be eliminated, leave the buildings and notify the
emergency services immediately.
