Triggering and end of a high threshold alarm
‘Intermittent alarm’ type tests detect short but frequent overshoots. A time window and a number of
acceptable overshoots during this time window must be set. For instance, if we do not want more than 5
overshoots within 2 minutes, a counter will start at the 1
st
overshoot. At the 6
th
overshoot within the 2 minute
window, an alarm is sent. The state is reinitialized when the number of overshoots within a 2 minute period is
lesser than or equal to 5.
