2.u - INDICATION OF GAS WARNING AND GAS ALARM
When the gas concentration is reduced to values lower than the intervention
threshold the device comes back to the normal operation conditions, all the
alarm indications stop and the relay is de-activated
(fig. 3).
If the yellow LED is permanently ON and
is accompanied by short buzzer signals,
this indicates a breakdown or fault in the
appliance, detected by the self-

If the gas concentration in the air exceeds the intervention threshold, the appliance
indicates this situation by activating the red LED alarm and simultaneously emitting an
intermittent buzzer sound (fig. 4).
If the gas presence alarm situation lasts for longer than 30 seconds, the appliance relay is
activated and closes the solenoid valve, if connected (fig. 5).
