6.6.2 Reset alarms

The alarms can be reset manually, automatically or automatically with retries:

• Manual reset: when the cause of the alarm has stopped, the buzzer must first be reset using the

ALARM

button and then the

ALARM

button pressed a second time for a true reset. At this point, even

the specific alarm action is reset and the device can restart.

• Automatic reset: when the alarm condition stops automatically, the buzzer is silenced and the alarm

reset.

• Automatic reset with retries: The number of interventions per hour is checked. If that number is less

than the set maximum, the alarm is on automatic reset, once the limit is exceeded it becomes manual.
