1WALL MOUNTING
Sicurgas P11 and P12 it is a device, that through
a sensitive sensor, detects methane gas
concentration (P11) and LPG concentration (P12) in
domestic environments.
Sicurgas P11 and P12 are operating when the gas
concentration in the air is much below of the lower
explosion limit (L.E.L.).
In case of alarm, interferes as well an acoustic
and light alarm that is going to prevent the danger.
Simultaneously Sicurgas is making the relay to
interfere to control the gas interception valve.
EXISTS THE POSIBILITY THAT YOU FEEL THE
GAS SMEL BEFORE THE DEVICE GIVES AN
ALARM SIGNAL.
Gas detectors Sicurgas P11 and P12, when are
connected to a normally closed (NC) valve with
manual reset are giving positive safety.This
means that the gas interception valve is closing to
interrupt the inflow, as well in case of line voltage
absence.
For having the maximum security can be used
more gas detectors Sicurgas, connected to the
same gas interception valve.
For e.g. can be mounted a P11 (P12) in the place
where is installed the boiler and another one in the
kitchen to control the stoves.
Sicurgas is supplied with a base suitable for
mounting in built-in boxes with 3 modules or in
round boxes.
Remove the base/cover retaining screw and ease off
the cover.
Fix the base on the wall (see paragraph 3) or in a
built-in box using rear entry for the entries of the
connection cables.
ATTENTION!
DO NOT OPEN THE DEVICE, BECAUSE
THIS MAY CAUSE ELECTRICAL SHOCKS OR
MALFUNCTION.
ATTENTION
gas detector installation is not released
from compliance with all rules regarding
features, installation and use of the gas
appliances, ventilation of the rooms and the
discharge of the combustion products prescribed
by the EN norms, implementation of the Art. 3 of
the law 1083/71 and of the national legislation
in force. Before installing the device, it is
recommended to read carefully this instruction
manual.

After executing the mounting and the connections (see paragraph 4) replace the cover on the base ensuring
the two cover pegs are correctly located on the two latching tabs. Screw again the fixing screw and apply in
the corresponding place the provided adhesive label indicating the replacement date.

SICURGAS PLACEMENT
EXAMPLES OF CONNECTION
ELECTRICAL CONNECTIONS
Sicurgas P11 must be fixed on the wall, about 30
cm from the ceiling and at a distance from gas
user device, between a minimum of 1 meter and a
maximum of 4 meters, in such position as to allow
natural air circulation.
Sicurgas P12 must be installed approximately 2
meters (minimum 1m maximum 4m) from the gas
user device and about 30 cm from the floor.
Sicurgas P11 is already equipped with two internal
alarms: one visible and one acoustic.
Just connect the line 230V c.a. 50Hz to the
terminals 4 and 5 to ensure the gas presence
signaling in the environment.
It is recommended to use a valve with manual
reset to stop the gas supply when there is an alarm
situation.
The internal relay can control all kind of power
supplied valves with manual reset:
normally closed (NC), always power supplied,
which require a commutating stable relay;
normally opened (NO), which require an
impulse relay.
Example of connection with stable relay, always
power supplied, to control a normally closed valve
with manual reset (down switch).
The system guarantees maximum safety, the gas
inflow will be stopped in case of:
gas concentration threshold exceeding;
power supply lack of the valve only or of the
detector;
connection breakdown between the detector
and the valve. For device power supply, connect
the terminals 4 - 5 to the circuit
230V-50Hz.
Relay operating mode can be chose in the
installation moment, by moving a switch (JP6) on
the printed circuit, normally supplied for functioning
with stable relay for NC valves (down switch).

FOR METHANE AND LPG
ATTENTION!
DO NOT place the device behind or under
cabinets or shelves that are not allowing the
natural air circulation in environment.
DO NOT place it near aerators (minimum distance 2
meters).
DO NOT place it on the vertical bakery surfaces,
steam sources, in places where can be achieved by
splashing water, near sinks, etc.
DO NOT place where environmental conditions are
different from the prescribed operation conditions.

OPERATION

IMPULSE RELAY, WITH CURRENT ACTIVATION,
TO CONTROL A NORMALLY OPENED VALVE WITH
MANUAL RESET (SWITCH IN UP POSITION)
The connection will ensure the interruption of the
gas inflow in case of gas concentration threshold
exceeding.
Sicurgas is provided with a TEST/SILENCING key, that allows to check the installation or to inhibit the
alarm. This key is activated through a cord for P11 methane gas (installed about 30 cm from the ceiling) or
through a button located on the body of P12 LPG (installed about 30cm from the floor).
To test the installation press the TEST/SILENCING key for 10 sec. In this way will be activated a control
procedure of about 30 sec., during which will be checked installation components.
Alarm inhibition is used instead to avoid an involuntary intervention of the detector, in fact Sicurgas sensor,
as all available on the market sensors, while being very selective can also participate for other substances,
for example: alcohol vapors, wine etc.
For example, during the use of wine while preparing food is possible, that the detector will enter in alarm
situation. To avoid this inconvenience press the TEST/SILENCING key for approx. 3 sec.
After having pressed the silencing key, for 10 minutes we will have a non-alarm situation: the buzzer
does not emits acoustic signaling, the relay returns in non-alarm position and the red and green led, are
flashing alternately to indicate the silence period; acting again on the switch during 10 minutes of the

OPERATION
At the first detector switch-on and after any power
supply failure, Sicurgas enters into pre-heating
and a sensor stabilization phase that continues
maximum 3 minutes. During this period will flash
alternately the red and green led indicating that the
device is not ready yet for gas detection. After this
period just the green led will remain switched on.

OPERATION
Sicurgas
silence period, the detector will immediately resume the normal operation.
After 10 minutes, the detector resumes automatically the normal operation.
Here is possible, knowing that can be used substances which can cause a false alarm, to reduce in advance
detector’s sound to prevent the signalizations and gas shut off of the stoves (due to gas valve intervention).
ATTENTION! in case of alarm:
1. turn off all opened flames in the room.
2. close the tap of the gas meter or of the L.P.G. gas cylinder.
3. do not switch on or off lights, do not operate electrical equipments or other electrically operated
devices.
4. open the windows and the doors to raise the ventilation inside the room.
5. do not use telephones in the room where you suspect gas presence.
If the alarm stops it is necessary to identify the matter that caused it and act accordingly.
If the alarm continues and the gas leak cannot be identified or cannot be eliminated leave the room and
from outside call the emergency services.
SOME OF THE MOST COMMON SUBSTANCES THAT CAN CAUSE FALSE ALARM ARE THE FOLLOWING:
wine - liquors - alcohol - deodorants - stain-removers - varnish thinners - hair spray - excessive steam.
Sicurgas also allows to set the type
of the acoustic alarm, see picture on
the side.

7MAINTENANCE AND CLEANING
Pay attention to temperature values or to the extreme humidity.
To give the maximum security the detector must be constantly powered.
For routine maintenance and for the temporary closing-down of the device, it is recommended to contact
an authorized technician.
Regularly check the correct operation using the appropriate button or a gas test.
OTHER TEST METHODS MAY DAMAGE THE EQUIPMENT.
To clean the unit, use a soft cloth without using chemical cleaners or solvents.
