OPERATION
SICURGAS is a device that uses a highly sensitive probe to detect the presence of dangerous concentrations of METHANE gas.
Sicurgas is complete with two internal alarms: one luminous and one acoustic.
SICURGAS intervenes with a pre-alarm when the gas concentration is well below the lower explosive limit (LIE), immediately turning on the red light and activating any signalling device (e.g. modem).
If the pre-alarm state persists and the concentration consequently increases as a function of the LEL, the alarm is triggered, which in addition to the visual signal also activates an acoustic signal to warn of the danger. At the same time, SICURGAS activates a relay to control a gas shut-off valve.

CHARACTERISTICS
Case made of shock-absorbing insulating material.
Internal light and sound alarm.
There are three warning lights on Sicurgas:
„„ Green LED indicates that the detector is working properly;
„„ Yellow LED indicates a fault in the detector;
„„ Red LED indicates the presence of gas in the environment (ARM ALARM).
Interchangeable semiconductor sensor for gas detection.
Sensor lifespan 5 years from installation.
The relay used is of the sealed type and filled with inert gas, which in any case allows for the absolute absence of sparks during the switching phases.
Internal selector (jumper) for choosing the relay operating mode: stable or pulsed.
Cord/Button for silencing the alarm in the event of intervention by alcohol vapours or some of the most common substances that can cause a false alarm.
