In installations with multiple appliances which are BUS connected to a main unit, the
peripheral units, 15 seconds after the "gas presence alarm" state is activated, transmit
a signal to the main unit, which is placed in "gas presence alarm from BUS" state.
Warning: gas can be smelt in the environment before the
appliance signals alarm.

The appliance memorizes when an alarm

been an alarm in the environment (the 3 red

To clear the alarm memory, press the
" RESET " button and the appliance will
