The coding is as follows : 1 : Alarm detected
 Alarm Data Field: the signification of this field depends on the alarm type.
When the alarm is a leakage (extreme or residual) detection, this field corresponds to the consumption-rate
value. When the alarm is a sensor default, this field represents the type of default detected.
