Alarm management
The standard alarm sequence includes three steps:
Case 1
: acknowledgement before the end of the alarm event
1.
Start of alarm event
:
input switches from normal to alarm condition.
Buzzer switches on and the corresponding alarm led becomes blinking,
indicating an unacknowledged alarm status.
2.
Alarm acknowledgement:
user pushes CANCEL HOOTER pushbutton.
Buzzer stops and alarm led switches from blinking to fixed, indicating an
acknowledged alarm status.
3.
End of alarm event:
input switches from alarm to normal condition.
Alarm led switches from fixed to off.
Case 2
: acknowledgement after the end of the alarm event
1.
Start of alarm event:
input switches from normal to alarm condition.
Buzzer switches on and the corresponding alarm led becomes blinking,
indicating an unacknowledged alarm status.
2.
End of alarm event:
input switches from alarm to normal condition.
Same signals continue, system remains in previous alarm status.
3.
Alarm acknowledgement:
user pushes CANCEL HOOTER pushbutton.
Buzzer stops and alarm led turns off.
The alarm management is “with memory”; namely, if the end of the alarm
event occurs before the acknowledgement, the equipment remains in
unacknowledged alarm status, until the acknowledgement.
Acknowledgement operation is effective over all the current alarms.
