Sicurgas P11 and P12 it is a device, that through
a sensitive sensor, detects methane gas
concentration (P11) and LPG concentration (P12) in
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.

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
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
