Alarm load
(rate of new alarms)
Desigo CC has been tested for the alarm loads
defined below. Do not exceed:
Constant load of 1 alarm per second on average
10 alarms per second on average over a period of 20
minutes
50 alarms per second over a period of 20 seconds
(alarm burst)

reduced depending on the complexity of the OPS.
