3.u - INDICATION OF GAS WARNING AND GAS ALARM
If the gas concentration in the air exceeds the intervention threshold, the appliance
indicates this situation by activating the red LED 1 alarm and simultaneously emitting an
intermittent buzzer sound (fig. 6).
If the gas presence alarm situation lasts for longer than 15 seconds, the appliance relay is
activated and closes the solenoid valve, if connected (fig. 7).

Where several units are BUS
connected, peripheral units in "gas
alarm level" status will transmit a
signal to the main unit, which
switches to "gas alarm level from
BUS" status.
This condition is indicated by red LED
1 only, which remains permanently
alight (Fig. 8).
