Alarms: AD.A module
Logic on alarm management
•
The system checks the status of each alarm in every verification cycle identified in
the software.
•
The signal of alarm active state after a time to trigger, during which the alarm
condition should persist (the time to trigger is variable upon the type of alarm and
operative mode in use).
•
The alarm foresees a LED signal.
•
The alarm foresees an acoustic signal.
•
The alarm can be suspended or not by the ALARM RESET control (the interval of
suspension of acoustic signal is variable upon the type of alarm).
•
Only the power failure alarm can be inhibited by the user through the ALARM
RESET control; (an inhibited alarm remains in such a state until the trigger
condition persists, after that it comes back to the inactive state).
8-4
•
In case of concomitance of more than one alarm the level of
acoustic signalling will correspond to that with major priority; the
suspension is for all the alarms which are active in that moment.
•
If, on the contrary, the trigger condition is no more real, the
alarms come back to the inactive state prior suspension of the
alarm.
The power failure signal is evidenced by flashing led that changes
colour.
