11. CHARACTERISTICS AND INTERPRETATIONS

Automatic control of the siren 17 and of the remote alarm B by means of the water level control float.

Manual control for silencing the siren 17 and the remote alarm B by means of the button 16 on the front of
the panel.

Automatic control for switching on the independent feed device of the control unit in the event of lack of
supply voltage.

Automatic control for excluding the acoustic alarm 17 and the remote alarm B which holds the warning
light 18 in the event of low battery charge.

Automatic control for excluding the control unit in the event of the battery charge being below the limit.
