Allows the action of the job to be selected as:

2. on becoming active, on becoming inactive or on acknowledgement

Figure 4.3.3g, below, shows the various actions graphically. For 'While unacknowledged' and 'on acknowledgement'
settings, two cases are shown, one where the alarm goes inactive before acknowledgement; the other where the alarm
is acknowledged whilst the alarm is still active. The coloured (shaded) areas show the duration for which continuous
jobs run; the down arrows show trigger points for 'one-shot' jobs. See
for details of how to acknowledge
alarms.
